of the Philippines”
a De La Salle University Project under the PCIEERD-DOST
PROGRAM FOR REHABILITATION AND RESTORATION
OF MINING AREAS THROUGH PHYTOTECHNOLOGIES
with Ateneo de Manila University and
The University of the Philippines Los Banos
This document describes a project to identify plant species in the Philippines that can be used as bio-indicators of heavy metal contamination from mining. The project involves surveying plants found in metal-rich and non-metal rich soils at six study sites across the country. The objectives are to create a database of metal-accumulating plants and study their potential use for restoring mined areas. Implementing agencies will collect and analyze plant and soil samples to classify species based on their ability to extract and store heavy metals.

Three major biozones are identified from micropalaeontological analysis of formations from the late Jurassic to early Cretaceous in Kuwait. The Makhul Formation contains a radiolarite assemblage indicative of restricted muddy limestones. The Minagish Formation and Ratawi Limestone Member contain calcareous algae and foraminifera assemblages representing shallow shelf carbonates. The Ratawi Shale Member contains a foraminifera assemblage representing a mixed clastic and carbonate environment. Within these three biozones, a number of subsidiary biofacies divisions are also identified, allowing recognition of vertical stacking patterns and depositional cyclicity in this important hydrocarbon-bearing interval.
This project aims to (1) study the cycling of natural and anthropogenic carbon in Ireland's marine environment and (2) examine chemical and biological processes at cold seeps in Irish waters. Advanced molecular and analytical techniques will be used to characterize the source and fate of organic compounds like hydrocarbons in sediments and identify the microbial communities involved in degradation. Specifically, the project will analyze carbon cycling in the Irish Sea mudbelt and at cold seep sites, and seek to understand the controls on organic compound distribution and the microbes breaking them down.

The document discusses soil health and its assessment. Soil health refers to the biological, chemical, and physical features essential for sustainable agriculture with minimal environmental impact. It cannot be directly measured but can be inferred by measuring specific properties like organic matter content and observing soil status. There is interest in studying soil microorganisms and their relationship to soil structure and function. Determining soil health indicators that can evaluate current status helps develop sustainable agriculture systems. Modern techniques now enable rapid measurement of soil microbial communities and analysis of microbial diversity and activity.
The document provides information on soil classification systems including genetic and modern systems. It discusses orders, suborders, and great groups within these systems. It also covers various soil properties like texture, minerals, pH, and nutrients. Primary minerals discussed include feldspar, mica, silica, and iron/aluminum oxides. Secondary minerals include carbonates, phosphates, zircon, pyrites, and clay minerals. Soil pH and its effect on nutrient availability is also summarized.
This document summarizes research on monitoring and modeling nitrate and metolachlor fate in the Choptank River watershed in Maryland. Key findings include:
1) Nitrate and its metabolite MESA showed a strong linear correlation in subwatersheds and throughout the Choptank River estuary, indicating nitrate is conserved during transport.
2) The ratio of nitrate to MESA in subwatersheds correlated with the percentage of cropland on hydric soils, suggesting these areas are a primary nitrate source.
3) Preliminary analysis of the Greensboro and Tuckahoe sub-basins found the Tuckahoe exports twice as much nitrate despite similar
The document discusses a study analyzing soil samples from the Catholic 40 Superfund site in Oklahoma, which was contaminated by extensive lead and zinc mining. Soil samples were tested to determine heavy metal concentrations and compare them to EPA thresholds. Results found zinc concentrations exceeding toxicity thresholds, suggesting amendments by the EPA to remediate the site were not fully effective due to shallow soil, lack of vegetation cover, and other factors. The study recommends further analysis, continued pH monitoring, and planting of zinc-tolerant plants to stabilize the soil.

Limited acid soil fertility is caused by a high concentration of H+ and Al3+, some organic acids and heavy metals, but also by a small accessibility of some nutrients (P, Ca, Mg, B, Zn, particularly Mo) and a small microbiological activity. This study has been conducted to determine the effect of three levels of liming (partial – 1/3 Y1, half – 1/2 Y1, and complete liming) on the neutralization of the acid reaction, a high content of mobile Al3+, and changes in the concentrations of available forms of Fe, Zn, and Cu in Dystric cambisol soil. The complete liming has almost completely neutralized the acid reaction, and decreased the level of mobile Al3+ below 1.0 mg kg-1. There
has been a satisfactory degree of decrease in pH and Al3+ in partial (1/3 of Y1) and half (1/2 of Y1) liming. No level
of liming has had a significant influence on the content of available forms of Fe and Cu, while the content of Zn
has decreased in accordance with the level of entered lime material and has been the lowest at the maximum doses of CaO applied. The level of changes caused by partial and halh-liming has justified these levels of acid repairing, which can be a great ecological and economic importance.

This document discusses the transformation of nitrogen, phosphorus, potassium, and sulfur in soils. It describes the key processes involved in each transformation, including mineralization, nitrification, denitrification, immobilization, solubilization, and oxidation/reduction. It notes that microorganisms play a critical role in transforming organic forms of nutrients into plant-available inorganic forms through the secretion of enzymes and organic acids. Specific microbes involved in each transformation are also outlined, such as nitrifying bacteria, phosphate solubilizing bacteria and fungi, potassium solubilizing bacteria, and sulfur oxidizing bacteria.
Giant freshwater microbialites up to 3 meters in diameter and height are found along a 10 km stretch of Laguna Bacalar lagoon in Mexico. The microbialites are composed primarily of low-magnesium calcite precipitated by the metabolic activity of cyanobacteria and diatoms. Elevated carbonate concentrations in the lagoon waters, derived from dissolution of limestone in the underlying karst system, support carbonate precipitation. The microbialites grew between 9,000-8,000 years ago but appear to no longer be actively forming due to grazing by abundant molluscs. The Laguna Bacalar microbialites represent one of the largest known occurrences of freshwater microbialites worldwide.

The document discusses the development of an Ecosystem Health Monitoring Program (EHMP) for streams and rivers in southeast Queensland, Australia. It outlines the process used to design a cost-effective monitoring program, including developing conceptual models, classifying waterways, pilot testing indicators, and a major field trial to evaluate the response of indicators to disturbance gradients. Key indicators were selected for the EHMP based on their ability to detect various types of disturbance and their association with catchment characteristics.
This document summarizes a study characterizing a landfill in Mohammedia, Morocco. Samples were taken from 5 stations around the landfill and near the El Maleh river to analyze physical and chemical properties. Heavy metals like lead and chromium were found in high concentrations in leachates from the landfill and sediments near the river. Pollution from the landfill's discharge was impacting the river water quality. The aim was to evaluate the physico-chemical quality of El Maleh river water in relation to leachate from the converted clay quarry landfill and identify a rehabilitation plan.
Potassium is an essential mineral that regulates important bodily functions in humans and plays a key role in plant growth and photosynthesis. It is obtained through foods like fruits, vegetables, dairy products, and meat or through fertilizers and soil. In plants, potassium is necessary for carbohydrate metabolism, enzyme activation, osmotic regulation, and protein synthesis. It is also essential for photosynthesis and nitrogen fixation in legumes. The potassium cycle involves potassium moving between soil, plants, animals and decomposing matter through processes like leaching, runoff, erosion and existing in soil solution.
2011_Important Determinants for Fucoidan Bioactivity A Critical Review of Str...Marcel Tutor Ale, PhD
This document reviews important determinants for the bioactivity of fucoidan, which are fucose-containing sulfated polysaccharides found in brown seaweeds. It discusses how the extraction method used to obtain fucoidan from seaweed is crucial for retaining structural features that influence its biological activity. A historic overview of early fucoidan extraction methods shows they often co-extracted contaminants. More focus on extraction procedures is needed to understand structure-function relationships and standardize fucoidan for applications.
The document presents information on phosphate fixation in soils. It discusses how phosphorus is an essential nutrient for plant growth but is limited in about 40% of the world's soils due to fixation reactions. These reactions reduce the solubility and availability of phosphorus by adsorbing phosphate ions onto soil particles like iron, aluminum, and calcium compounds. The degree of fixation depends on soil properties like mineral composition, pH, and calcium carbonate content. Phosphate can be temporarily or permanently fixed depending on the reaction conditions, reducing phosphorus efficiency in soils to 10-20%.
The document analyzes phosphorus speciation in dairy-manure amended soils in Idaho through various methods including sequential extraction, NMR spectroscopy, and XAFS. The key findings are:
1) Phosphorus in the soils is primarily found as calcium-phosphate minerals, though some adsorbed and organic phosphorus species are also present.
2) With increasing manure addition, more phosphorus adsorbs to iron oxides in the soil rather than forming calcium-phosphate phases, likely due to inhibition by organic matter in the manure.
3) The research provides insights into phosphorus behavior in manure-amended agricultural soils and implications for managing dairy waste and nutrient cycling.
Removal of nitrogen and phosphorous in soilVinoth Sugumar
This document summarizes nitrogen and phosphorus removal processes in soil. It discusses that nitrogen and phosphorus are essential nutrients for plants and animals. The key nitrogen removal processes are plant uptake, gaseous loss through ammonia volatilization and denitrification, immobilization, leaching, runoff, and erosion. The phosphorus removal processes covered are plant uptake, sorption and desorption, precipitation and dissolution, mineralization and immobilization, and leaching and runoff. Factors that influence different removal processes like soil properties, climate, and management practices are also outlined.
Potassium is essential for many plant and biological functions. It makes up 2.6% of the Earth's crust and 0.2% of the human body. Potassium was first isolated in 1807 and comes from minerals like feldspar and mica in the soil. Plants accumulate potassium, making fresh fruits and vegetables a good dietary source. Potassium is lost from soil through erosion, runoff, leaching, and harvesting of plants, so fertilizers are needed to replenish potassium in agricultural production.
This document discusses potassium (K) in soils. It covers the following key points:
- K exists in soils in various forms including solution, exchangeable, fixed, and structural/mineral forms. Exchangeable K is the most plant-available.
- K is essential for plant growth and plays important roles in processes like photosynthesis and enzyme activation. Deficiency causes burn symptoms on older leaves and reduced yields.
- Common fertilizers containing K include potassium chloride, potassium sulfate, and potassium magnesium sulfate. Fertilizer K can increase various forms of K in soils.
- Factors like clay content, soil pH, wetting/drying, and freezing/thawing can influence K
There are seven identified prioritized abandoned mine sites: Philippine Pyrite Corporation - Bagacay, Hinabangan, Western Samar; Basay Mining Corporation - Brgy. Maglinao, Basay, Negros Oriental, Thanksgiving Mine, Benguet Exploration Inc. - Camp 6, Kennon Road, Tuba, Benguet, Black Mountain Inc. - Tuba, Benguet, Consolidated Mines, Inc. - Ino & Capayang, Mogpog, Marinduque, Palawan Quicksilver Mines - Tagburos, Puerto Princesa, Palawan, Western Minolco Corp. - Atok, Benguet The Bagacay Mine in Western Samar ranks first for remediation. The Bagacay site, which was formerly worked for the recovery of pyrite/copper, is located at the border of a nature reserve. It exhibits many environmental problems, including the formation of Acid Mine Drainage (AMD) and the related spread to nature of potential toxic metals. MGB has conducted a preliminary investigation into the environmental impacts at Bagacay Mine and developed some initial rehabilitation plans including some revegetation trials. These plans are insufficient for final closure and rehabilitation but can be identified as interim remediation measures...
The nitrogen cycle involves the circulation of nitrogen between the atmosphere, biosphere, lithosphere and hydrosphere. Nitrogen is essential for life but is biologically unavailable in its atmospheric form. Certain bacteria are able to fix nitrogen by converting it to ammonia. This ammonia can then be converted to nitrites and nitrates through nitrification or incorporated into living things through assimilation. Upon death and decomposition, nitrogen is returned to the soil through ammonification. Denitrification returns nitrogen to the atmosphere, completing the cycle. Human activities like fossil fuel combustion and excessive fertilizer use have disrupted the nitrogen cycle, contributing to issues like acid rain, eutrophication and algal blooms.
Potassium is an essential nutrient for plant growth. It is involved in many important plant processes like photosynthesis, enzyme activation, and water regulation. While total potassium content in soils is usually high, most of it is unavailable to plants. Only a small portion in the forms of exchangeable and water soluble potassium is readily available. Maintaining adequate available potassium levels through fertilization is important for optimal plant growth, yield, quality and stress resistance. Deficiency can cause various symptoms like chlorosis and stunted growth. Proper soil testing and balanced fertilizer management practices are required to supply potassium needs of crops and minimize losses and environmental impacts.

The document summarizes comparative genomic analyses of the human pathogenic fungi Coccidioides immitis and Coccidioides posadasii. Genomes from 13 strains of the two Coccidioides species were sequenced and analyzed to reconstruct their evolutionary history and population structure. Phylogenetic analysis of the strains supported the distinction of the two species and identified potential introgression between species. Comparative genomics was also used to search for genetic differences underlying variations in virulence and distribution between strains that may provide insight into the molecular basis of Coccidioides pathogenesis.
The document discusses using bio-indicators to monitor pollution levels. It focuses on using lichens and pond ecosystems to test for air and water pollution. Lichens can indicate air quality, with more elaborate lichens found in cleaner air. Nitrates from farm fertilizers can pollute ponds if washed by rain, with potential effects including increased nitrate levels. Samples will be taken from ponds near farms to analyze nitrate levels and determine the impacts.

This document summarizes research on developing an orthogonal fatty acid biosynthesis system in E. coli for oleochemical production. Key findings include:
- Several type I fatty acid synthase (FAS) enzymes from Corynebacterium glutamicum and Mycobacterium tuberculosis were cloned and expressed solubly in E. coli.
- The activity of several type I FAS enzymes was demonstrated in vivo, and C. glutamicum FAS was used to produce fatty alcohols and methyl ketones.
- This represents the first example of a heterologous FAS pathway in E. coli and lays the groundwork for further optimizing renewable oleochemical production.
Neurospora is a genus of fungi that includes the species N. crassa, which is used as a model organism in biology research. It has septate, branched mycelium and reproduces asexually through macroconidia and microconidia. Sexually, it produces female ascogonia which receive nuclei from conidia via plasmogamy and develop into perithecia containing asci with ascospores. Pleurotus mushrooms are edible fungi that grow on wood. They reproduce asexually through arthroconidia produced on coremia. Sexually, dikaryotic mycelium form the fruiting bodies after karyogamy and meiosis within basidia

Gene interactions can modify Mendelian ratios expected from monohybrid and dihybrid crosses. There are several types of gene interactions:
1. Complementary gene interaction results in a 9:7 ratio when two genes work together to produce a trait.
2. Duplicate gene action occurs when genes encode redundant functions, resulting in a 15:1 ratio.
3. Dominant gene interaction yields a 9:6:1 ratio when dominance of one gene masks the other.
4. Epistatic interactions alter Mendelian ratios by one gene modifying another's expression. This includes recessive epistasis (9:3:4 ratio) and dominant epistasis (12:3:1 ratio).
This document discusses environmental monitoring and various methods used for it. It covers the following key points in 3 sentences:
Environmental monitoring involves systematically sampling air, water, soil, and biota to observe the environment and gain knowledge. It is undertaken for reasons such as identifying pollution levels, sources, and effects on health. Common monitoring methods include ground-based sampling, modeling, and satellite-based monitoring of various environmental aspects such as atmosphere, land, water quality, and natural hazards.
The document provides an overview of microbial monitoring in a manufacturing area. It discusses:
1) The purpose of an environmental monitoring program is to provide crucial information on the quality of the aseptic processing environment during manufacturing and to prevent the release of contaminated batches.
2) Microbial monitoring tests for viable and non-viable particles in critical areas like cleanrooms, tank rooms, and packaging areas to demonstrate control of microorganisms.
3) Sources of contamination can come from air, personnel, equipment, cleaning agents and more. Monitoring must meet regulatory standards from agencies like FDA, ISO, and USP.
Bioindicators are organisms that can be used to monitor environmental health. Different types of bioindicators like plants, animals, and microbes indicate different types of pollution or environmental changes. Scientists observe changes in bioindicator populations to assess environmental conditions. This document provides examples of various bioindicator species and how they are used, including lichens for air quality, earthworms for soil toxicity, and diatoms for water acidity. It also outlines classifications of bioindicators and criteria for selecting effective bioindicator species.
Value chain analysis is a tool used to identify sources of competitive advantage. It examines a firm's activities and how they interact and affect costs and performance. Michael Porter developed the value chain model which divides a firm's activities into primary and support activities. Primary activities directly involve creating and delivering a product. Support activities provide inputs for primary activities. Tata Motors' value chain includes long-term supplier contracts, efficient manufacturing processes, a large dealer network, and investments in research and development. Analyzing a firm's value chain can reveal opportunities to lower costs or differentiate products compared to competitors.

Iron acquisition and mineral transformation by cyanobacteria living in extrem...Sérgio Sacani
Iron is an essential micronutrient for most living organisms, including cyanobacteria. These microorganisms have
been found in Earth's driest polar and non-polar deserts, including the Atacama Desert, Chile. Iron-containing
minerals were identified in colonized rock substrates from the Atacama Desert, however, the interactions be-
tween microorganisms and iron minerals remain unclear. In the current study, we determined that colonized
gypsum rocks collected from the Atacama Desert contained both magnetite and hematite phases. A cyanobacteria
isolate was cultured on substrates consisting of gypsum with embedded magnetite nanoparticles. Transmission
electron microscopy imaging revealed a significant reduction in the size of magnetite nanoparticles due to their
dissolution, which occurred around the microbial biofilms. Concurrently, hematite was detected, likely from the
oxidation of the magnetite nanoparticles. Higher cell counts and production of siderophores were observed in
cultures with magnetite nanoparticles suggesting that cyanobacteria were actively acquiring iron from the
magnetite nanoparticles. Magnetite dissolution and iron acquisition by the cyanobacteria was further confirmed
using large bulk magnetite crystals, uncovering a survival strategy of cyanobacteria in these extreme
environments.
Speciation of heavy metals in the soil and the tailings, in the zinc lead sid...Alexander Decker
This document summarizes a study on the speciation of heavy metals in soil and tailings samples from the abandoned Sidi Bou Othmane zinc-lead mine in Morocco. Total metal concentrations and sequential extractions were performed to determine the chemical forms and potential mobility of cadmium, copper, lead and zinc. The tailings had much higher metal levels than the surrounding soils. Most soils near the mine exceeded thresholds for zinc, lead and cadmium, indicating high pollution. The study aimed to evaluate the contamination risk posed by the abandoned mine wastes.
Program for the rehabilitation and restoration presentation2 Maricar Onggon
This document outlines a program to rehabilitate mined out areas in the Philippines using phytotechnologies. It describes 3 projects, each led by a different project leader and focusing on: 1) conserving native metallophytes and testing phytostabilization in Palawan, Surigao, and Zambales, 2) identifying metal bioindicator species in 6 sites and creating a database, and 3) identifying copper and arsenic hyperaccumulators for potential post-mining metal recovery. The overall objectives are to study indigenous metallophyte species for phytotechnologies and develop protocols for their propagation and use in phytoremediation and post-mining activities.
The copper isotope ratios were measured in 42 mineral separates from the Cañariaco Norte porphyry copper deposit in northern Peru. Isotopic ratios ranged from -8.42‰ to 0.61‰, with near-surface iron oxides having the most depleted values and deeper chalcocite, covellite, and chalcopyrite having more typical hypogene ratios. The data indicate that most of the chalcocite and covellite formed from high-temperature hypogene processes, with only a minor portion resulting from supergene enrichment. The lack of an enriched isotopic signature suggests little potential for an extensive supergene enrichment blanket at depth due to the weathering history.
This document summarizes a talk given at the Geological Survey Technical Talks on June 1st, 2016 in Orange, NSW.

This included an overview of recently completed metallogenic maps of the Bathurst and Broken Hill areas at 1:250,000 scale, which updated deposit information and incorporated mineral system models. Future work discussed included mineral potential studies and metallogenic syntheses of the Cobar, New England, and Macquarie Volcanic Province areas at 500,000 scale. The talk concluded with preliminary work on the new Cobar metallogenic project,
The document discusses mineral resources in the Philippines. It begins by defining mineral resources and describing how they are extracted from the earth's crust through surface and subsurface mining methods. It then discusses the various impacts of mineral extraction, including environmental impacts like pollution, habitat destruction, and social impacts like human displacement. The document emphasizes that while mining is important for the economy, it also causes significant environmental degradation that requires preventive measures and remediation.
This document discusses a study that examined the potential for three species of aquatic macrophytes (Pista stratiotes, Spirodela intermedia, and Lemna minor) to simultaneously remove several heavy metals from water. In laboratory experiments, the macrophytes were exposed to varying concentrations of iron, copper, zinc, manganese, chromium, and lead over 15 days. High removal percentages for all three species and metals were observed. However, L. minor did not survive the experimental conditions. The rate of metal uptake by the macrophytes was dependent on the initial metal concentration. Overall, the study evaluated the macrophytes' ability to remove multiple heavy metals from water to help treat naturally polluted environments.
The document describes geochemical and geochronological analyses of volcanic rocks in the Barby Formation in southern Namibia. Key findings include:
1) The Barby Formation contains basaltic trachyandesites, trachydacites, and rhyolites with calc-alkaline geochemistry, suggesting emplacement in an active continental margin setting.
2) U-Pb dating of zircons from four samples yielded ages of 1213.7 ± 4.8 Ma for the Barby Formation and 1217 ± 3 Ma for the coeval Spes Bonasyenite.
3) Lu-Hf isotopic analyses indicate the units formed from a mixture of younger and older

MICROPALEONTOLOGY : Introduction and its importance.pptxSurajKumarThakur1
Micropaleontology involves the study of microscopic fossils or microfossils to understand Earth's geological history. Microfossils can be indicators of certain minerals based on the environmental conditions they lived in and the rocks they are found in. For example, foraminifera are often associated with limestone due to their calcium carbonate shells contributing to carbonate-rich sediments. Diatoms and radiolarians frequently indicate siliceous minerals like chert because of their silica cell walls and skeletons. Integrating microfossil analysis with other geological data helps identify the minerals present in a sample and reconstruct paleoenvironments.
Drinking water quality assessment in lead affected communities in zamfara sta...Dogara Bashir
An assessment was conducted of drinking water quality in four communities in Zamfara State, Nigeria affected by lead poisoning from gold mining and processing activities. Water samples from 18 sources were tested for 22 parameters. Results showed high levels of lead, turbidity, and bacteria in many sources, likely due to mining waste contamination. A geochemical analysis found lead and other heavy metals in rocks from mining sites. Community members process mining materials within households, exposing adults and children to dust. Recommendations included providing new water sources, sensitization on hygiene, and monitoring to address contamination issues.
Otoliths are bony structures in fish that record chemical signatures from the surrounding environment over time. Analysis of otolith microchemistry can be used to identify fish stocks, determine habitat use and migration patterns. Elements like strontium and barium deposited in otoliths vary between freshwater, estuarine and marine environments. This allows distinguishing anadromous fish that migrate between habitats and tracking their movements. Studies have used this technique to study life histories of species in Amazonian rivers and identify nursery areas of herring. Otolith microchemistry is a valuable tool for answering ecological questions about fish.

World class hydrocarbon accumulations are often found in ancient basins containing evaporites. The distribution of carbonate and evaporite facies provides important seals and traps for hydrocarbon storage. Evaporites are deposited during sea level lowstands, forming thick basin-center deposits that later provide regional seals. Large evaporite deposits occur when tectonic, climate, and basin conditions restrict marine waters and enable net evaporation. Saline giants are found in continental interior sag basins, post-orogenic foreland basins, and late-stage rift basins. Facies transitions between carbonates and evaporites within sequences can also generate hydrocarbon traps and seals.
Considering the importance of the healthy coral reef ecosystems to Langkawi’s economy as well as to the global coral reef biodiversity, the present study provided the baseline database regarding on distribution of heavy metals concentration (Cd, Cu, Pb) and the trend of heavy metals accumulation in Diploria Labyrinthiformis and Favia Pallida corals at Pulau Langkawi region. This report showed the level of heavy metal contamination in each of 5 years growth rate bands in both coral specie susing AAS. The averages of heavy metals concentration in Diploria Labyrinthiformis were 0.018±0.002 mg/L, 0.044±0.11 mg/L, and 0.120±0.01 mg/L for Cd, Cu, and Pb respectively. Meanwhile the concentrations of heavy metals for Favia Pallida were 0.017±0.02 mg/L, 0.088±0.004 mg/L, and 0.218±0.14 mg/L for Cd, Cu, and Pb respectively. Both species showed the low concentration and not exceeding the MPI safety level that indicated that the corals were not impacted by pollution. The trend and correlationships of the Cd, Cu, and Pb in the bands coral slab showed the increasing trend of concentration which were increased gradually from the surface (youngest) to bottom (oldest) layer for the samples.
Mineral prospecting and exploration involves searching for mineral deposits through various stages and techniques. It begins with initial prospecting through field research, mapping, and sampling. If results are promising, more detailed exploration is conducted including additional mapping, geochemical testing, geophysical surveys, and drilling. The goal is to accurately define mineral deposits and determine their economic potential to guide decisions on mineral extraction. Prospecting requires qualified individuals with geological and engineering backgrounds who can perform tasks like mapping, sampling, and using exploration equipment in various terrains and conditions.

2. Micropaleontology is useful in petroleum exploration for chronostratigraphy, identifying paleoenvironments, and reservoir exploitation. It is also applied in mineral exploration, engineering geology, environmental geology, and archaeology.
3. Microfossils can indicate environmental conditions and be used to study phenomena like global warming, ocean acidification, and their impacts on ecosystems.
The document describes a study characterizing a polymetallic concentrate from mining residuals in Portovelo, Ecuador and testing bioleaching using native microorganisms. The concentrate contained high levels of pyrite as well as gold, silver, and other metals. Native microorganisms isolated from mining sites were enriched and identified as Acidithiobacillus ferrooxidans. In bioleaching experiments, the microorganisms effectively solubilized sulfides at low pulp densities, releasing high concentrations of iron and sulfate. However, microbial activity and metal extraction decreased sharply at higher pulp densities, likely due to inhibition. The study suggests bioleaching could help process mining residuals in Portovelo but microbial adaptation to higher densities would be

1. “Metal Bio-indicator Plant Species
of the Philippines”
a De La Salle University Project under the PCIEERD-DOST
PROGRAM FOR REHABILITATION AND RESTORATION
OF MINING AREAS THROUGH PHYTOTECHNOLOGIES
with Ateneo de Manila University and
The University of the Philippines Los Banos
2. OBJECTIVES OF PROGRAM ARE:
To identify and study the biology-ecology and
chemistry of indigenous metallophyte
species that can be used in phytotechnologies
to restore mined-out areas
To develop a protocol for propagating
metallophyte species for use as metal bio-
indicators, phytostabilization and post-mining
metal recovery
3. SURVEY OF PLANTS IN METALLIFEROUS SOILS
AND MINED OUT AREAS
Collection and taxonomic identification of plants that are metallophytes
(or those plants that thrive even in metal-rich soil conditions); and within
the metallophyte species, identify those that are obligate or facultative
and those that are hyperaccumulators - these plant species can be used
as bio-indicators of heavy metal contamination and used for restoring
mined-out areas (in phytostabilization) as well as recovery of the metal.
DETERMINATION OF THE METAL CONTENT OF PLANT
(ROOT, STEM AND LEAVES) AND SOIL SAMPLES
Measurement of the heavy metal concentration of samples collected
from metalliferous soils compared with those collected from non-
metalliferous soils using Atomic Absorption Spectrometry (AAS)
CLASSIFICATION OF PLANT SPECIES BASED ON
CAPACITY TO EXTRACT METAL FROM THE SOIL AND
ACCUMULATE METAL IN THEIR TISSUES
Determining which plant species are capable of bio-indication, phyto-
extraction, and phyto-stablization using the ratio of metal content in soil
to plant tissue to determine capacity to “take away” metal from soil
4. THE GOAL OF THE PROJECT
is to develop an easy-to-use
and cheap technology, using
plants, to detect the presence
of heavy metals in soils, to
make detection, monitoring and
the clean-up of mining areas
easier for the mining sector and
citizens, to accomplish.
5. ALSO,
provide the mining sector and
citizens the capacity to recognize
and identify plant species that can
ONLY survive in the presence of
heavy metals (or obligate metal-
lophytes) and recognize the
CHANGES (adaptations) that occur in
the morphology of plants that can
survive in the presence or absence of
heavy metals (or those that are
facultative metallophytes).
6. PROJECT OBJECTIVE 1: Create a database of metal
hyperaccumulator plant species naturally occurring in
metal rich or ultramafic soils
Specifically:
1.1 Conduct a taxonomic survey, with gross morphological descriptions, of
metallophyte species (both hyperaccumulators and non-
hyperaccumulators) and other associated vascular plant species thriving in
metal rich and adjacent non-metal rich soils in six sites.
These include: 1) Kalinga, 2) Marinduque Island, 3) Rapu-Rapu Island,
Albay 4) Cebu, 5) Negros, and 6) Compostela Valley which are
representative of phytogeographic regions following the distribution of
ultramafics (metal rich or metalliferous substrates) in the Philippines
7. Specifically…
1.2 Compare the species found in metal rich soils with the species found in
adjacent non- metal rich soils and relate the distribution of
hyperaccumulator, non-hyperaccumulator and non-metallophyte (metal
tolerant or non-tolerant) species to soil chemistry.
1.3 Determine the distribution of the metals in the roots, stem and leaves
of hyperaccumulator plant species; identify the ligands; and compare the
protein profiles of selected hyperaccumulators with other metallophytes
and non-metallophytes.
2.1 Identify the obligate metallophytes (which may also be
hyperaccumulator) species, or those that are found thriving only in metal
rich soils; and facultative species , or those that are present in both metal
rich and non-metal rich soils.
2.2 Describe and compare the gross morphological, morphometric and
physiological characteristics of obligate, facultative metallophyes including
hyperaccumulator species and non-metallophyte species..

70. Training Protocol
through lectures and hands-on training
methods
• Introduction of the Project and the
Program
• Discussion of levels of participation
• Plant collection Techniques
• Field and Laboratory Safety
• Plant Identification Techniques
• Field Work and Field Documentation
• Sample Processing
71. TRAINING AND STARTER KIT PROVIDED PARTNERS CONTAIN:
• Books on Plant Identification; or pictorial guide books for the initial
identification of the plant collected in their vicinity / area
• Basic plant collecting equipment like pruning shears
• Basic Herbarium sheet preparation supplies like standard size Bristol
Board
• Plastic box / container for all the items and to serve as an example
storage container (correct size) for herbarium sheets (properly preserved
identified plants used as reference.
72. TRAINING OBJECTIVES
The ultimate goal is to:
help build the partner institution’s capacity to establish its own research (and
teaching) collection (herbarium and living) of local plants in the area. Going
beyond the project time horizon, these institutions become the “go to”
authority on the plants within their biogeographic or geopolitical areas. Any
future questions on the identity of plants (non-ornamental or non-food plant,
especially metallophytes) can then be resolved in consultation with experts
from national or international plant collection centers (like the Philippine
National Museum).
The practical goal is to:
help institutions develop their own herbarium, or at the very least,
learn to collect and preserve plants in a manner that renders the specimens
“identifiable” or in a way that plant taxonomists at the Philippine National
Museum or the DLSU System can identify
73. LESSONS LEARNED
• people request for plant to be identified by sending
photographs or sending plants improperly collected
(missing important parts) or those not properly
dried/preserved (decomposing or crumbling in
plastic bags)
• unless hands-on training and actual field collections
are conducted, little of the information on proper
plant collection and identification is retained
• details of simple techniques/procedures on scientific
plant collection and vegetation analysis can be taught
more effectively through experiential learning
74. LESSONS LEARNED
• questions on where to buy supplies used in
collecting, drying and preserving plant
specimen (herbarium preparation) always
arise
• Feedback from trainees is that on their own,
procedures and details of procedures for
collecting plants can easily slip their minds
without any guidebook or, even more useful,
a reference video (like a how-to cooking video
for scientific plant collection)

IN POTS) DETERMINE THE RESPONSE OF SELECTED
PLANT SPECIES TO KNOWN CONCENTRATIONS OF
HEAVY METALS UNDER CONTROLLED CONDITIONS
AND PREPARE FOR GOAL IN YEAR 3 TO:
DETERMINE HOW TO PROPAGATE BIO-INDICATOR
SPECIES FOR POTENTIAL USE IN THE FIELD FOR

FOR CLEAN – UP (PHYTOREMEDIATION)
82. OBJECTIVE 3: Determine the plasticity in the
morphological and physiological responses and
adaptations (or tolerance) of selected facultative
species exposed to varying concentrations of heavy
metals through a pot experiment. More specifically to:
3.1 Monitor selected facultative species to determine reproductive
phenology in order to collect seeds or cuttings to propagate them.
3.2 Expose test plants to varying levels of metals to determine tolerance
(germination, survival and growth) to increasing concentrations of heavy
metals.
