Soil Carbon Sequestration Potential of Mangroves at Katunggan it IbajayASU-CHARRM
The Katunggan it Ibajay (KII) Eco Park is home to one of the most diverse mangrove forests in the Philippines. It is a 44.22 hectares protected park in the town of Ibajay in Aklan which boasts a total of 28 true species of mangroves or 80 percent out of the total 35 Philippine mangrove species. The forest is also a home to some species of birds and other wildlife like mud lobsters, fiddler crabs, mudskippers and other fauna. Recent studies have been conducted in the area which includes the identification of mollusk species, behaviours and activities of fiddler crabs. However, there is a lack of information on studies regarding Carbon storage and sequestration potential of mangrove species in KII.
Therefore, considering the vital role of mangrove species there is a need to conduct this study to provide a wide array of information about the total C-stock and sequestration potential of selected mangrove species in KII. Likewise, it will help local folks, LGU-officials and future researchers to increase their awareness to protect and preserve KII Eco-Park; to help reduce increasing negative impact of global warming in the environment.

The carbon regeneration in the water column of
the Cariaco Basin (Venezuela) was investigated
using a regression model of total alkalinity (TA)
and the concentration of total inorganic carbon
(TCO2
). Primary productivity (PP) was determined
from the inorganic carbon fraction assimilated
by phytoplankton and the variation of the 22 and
23°C isotherm was used as an indicator of coastal
upwelling. The results indicate that CO2
levels were
lowest (1962 µmol/kg) at the surface and increased
to 2451 µmol/kg below the oxic-anoxic redox
interface. The vertical regeneration distribution of
carbon was dominated (82%) by organic carbon
originating from the soft tissue of photosynthetic
organisms, whereas 18% originated from the
dissolution of biogenic calcite. The regeneration
of organic carbon was highest in the surface layer
in agreement with the primary productivity values.
However, at the oxic-anoxic interface a second more
intense maximum was detected (70-80%), generated
by chemotrophic respiration of organic material
by microorganisms. The percentages in the anoxic
layers were lower than in the oxic zone because
aerobic decomposition occurs more rapidly than
anaerobic respiration of organic material because
more labile fractions of organic carbon have already
been mineralized in the upper layers.
This is an introduction to Maggie Ziriax\'s project on the stable isotope analysis of the teeth from Necropolis 6. Hopefully we can find out more about this population\'s diet and geographical origins from this analysis. Good luck Maggie!

Abstract
Soil organic carbon is one of the important elements and the major component of the soil. A complex biogeochemical cycle in the soil mostly dependent on the soil organic carbon (SOC). However, this experimental method measure the soil organic carbon in the Chandpai range, Sundarbans. The research has been found the soil organic carbon at very low portion in the study area and the different diversity index of different study plots of the forest. The sampling area contaminated with oil spill and affected by different human activities. Most of the studied focused on the different parameters of the forest soil such as soil pH, soil water holdings capacity, soil moisture etc. However, this study analyzes the soil to measure the soil organic carbon and calculate the biodiversity index in the Sundarbans

Environmental risk assessment of Macabalan creek water in Cagayan de Oro, Phi...Innspub Net
Creek water carries both domestic and commercial wastewater consequently draining organic and inorganic pollutants to coastal water. The present study dealt on the environmental risk assessment of creek water stretching in Macabalan-Cagayan de Oro, Philippines. Selected physicochemical analyses of water samples were carried in both temporal and spatial variations. Risk quotient (RQ), water quality index (WQI), and brine shrimp lethality test (BSL) was employed to draw environmental risk estimate. Overall, dissolved oxygen (DO) concentrations were below the standard set regardless of temporal and spatial variations. Both RQ and WQI showed good statuses on creek water quality despite the low DO. The BSLT similarly indicated a higher concentration for LC50 to be established. The study was preliminary and further monitoring may be essential.

Bioaccumulation of Lead (Pb) content in three species bivalves in Jakarta Bay...Open Access Research Paper
Environmental pollution by heavy metals has become a serious problem in Jakarta Bay. Mobilization of heavy metals as a result of anthropogenic activities has caused the release of heavy metals into the environment, one of which is Pb. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. In addition heavy metal pollutans in the waters are very stable and tend to be persistent. Recently, bioaccumators is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective using bivalves. These study objectives to analyzed the Pb content of three species of Jakarta Bay bivalves. The results showed that Pb content in the Eastern and Western Season bivalve tissue was significantly lowest in P. viridis (0,166 ± 0,016μg/g dan 0,161 ± 0,155μg/g) compared the Pb concentration in A. antiquata (0,264 ± 0,015μg/g dan 0,247±0,044μg/g), and M. meretrix (0,270 ± 0,016μg/g dan 0,240 ± 0,053μg/g). In this study also showed that the concentration of heavy metal Pb in the bivalve shell of P. viridis was significantly lower than that of two species (A. antiquata and M. meretrix). Pb content in the Eastern Season bivalves did not significantly different from that in the Westerrn Season. This is caused by a weather anomaly where the rainy season occurs almos throughout year of 2020. The Pb content in the bivalves shell was significantly higher than in the body tissues. It is because Pb can replace calcium ions in the formation of animal bones or bivalve shells.

New "research" by anti-drilling researchers at Johns Hopkins University that purports to show a connection between fracked shale wells in PA and an increase in radon in PA homes. Johns Hopkins Bloomberg School of Public Health researchers rather simplistically say that levels of radon in PA homes have been going up since 2004--when the first Marcellus Shale well was drilled in the state. They also say prior to 2004 levels of radon in PA homes was pretty much steady-state--that it did not increase. Since the "big thing" that's happened over the past decade is a lot of Marcellus drilling, voila, must be those nasty frackers are the source.

Aims of Project
To conduct a detailed chemical and physical
characterisation of the sediment in Dublin Bay.
The initial results will enable an investigation of
the type and abundance of organic pollutants and
biomarkers in Dublin Bay. These pollutants
include all 16 poly aromatic hydrocarbons (PAH’s)
and the biomarkers faecal sterols and
phospholipid fatty acids (PLFA’s).
Polyaromatic Hydrocarbons & Biomarkers
16 priority EPA PAH compounds will be
analysed along with faecal sterols and PLFA
biomarkers. PAH’s are significant due to their
environmental impact and their toxicity to
humans and other organisms (Tian et al.
2013). Bioaccumulation of these chemicals in
sediments occurs in sediments and benthic
organisms (Yates et al. 2011).
Extraction and analysis
PAHs, PLFAs and faceal sterols will be extracted
by SPE and analysed via GC-MS separation.
Optimisation of methodology is necessary to
produce highest yield of sample and lowest
background noise.
Funding
This project is joint funded by the GSI and Irish Research
Council through the Enterprise Partnership Scheme (EPS).
Previous Results
Geostatistical & Geospatial Approach
Mapping and sampling protocols will be
conducted with the use of statistical and
geographical tools. This process aims to
minimise sampling points whilst maximising
the knowledge of the sampled area.
Application of kriging and interpolation of the
sampled results will aid the development of
accurate maps.
There is a dearth of information both chemically and
physically on the area of Dublin Bay to be
investigated. However, this work is very much a
continuation of previous work conducted further out
in Dublin Bay which was recently published (Fig. 3)
(Murphy et al, 2016).
Preliminary work and results
Sampling of the bay was conducted at low tide in
March 2016. A sandy sediment, mud sediment and
salt marsh soil sample were taken from Dublin Bay
and Bull Island. An initial characterisation was
conducted but is currently ongoing.
