This research report examines heavy metal contamination from a gold mining plant in Oman. Samples were collected from soils, stream waters, and crop plants near the mining site. The samples were analyzed for 13 heavy metals. Water from an acid evaporation pond showed high iron concentrations and trace amounts of other metals. Surface water samples exceeded WHO standards for several metals. Soil and plant samples near the gold pit contained elevated levels of manganese, aluminum, nickel, iron, and zinc. The mining and ore processing activities, which use cyanide leaching to extract gold, introduce heavy metals into the environment that can accumulate in the food chain and pose health risks to humans and other organisms.

This work contributes to the monitoring of water pollution of some selected Dams in Katsina
State, North western Nigeria by assessing the degree of heavy metal pollution in the Dams sediment samples.
The study was conducted in the year 2017 within some selected Dams in the State (Ajiwa, Zobe,
Sabke/Dannakola) that are beehives of fishing and Agricultural activities in Katsina State. Analysis for the
concentration of these heavy metals; Cr, Cd, Fe, Ni, Mn, Pb and Zn was conducted by the use of AAS (by
Atomic Absorption Spectrophotometry) method. Several indices were used to assess the metal contamination
levels in the sediment samples, namely; Geo-accumulation Index (Igeo), Enrichment Factor (EF),
Contamination Factor (CF), Degree of Contamination (Cd), Pollution Load Index (PLI) and Potential
Ecological Risk Index (PERI). The result of this study has shown that generally among the heavy metals
evaluated, the highest concentration was observed for Fe (range: 2.6718-4.2830 ppm), followed by Zn (range:
0.4265-0.7376 ppm), Cr (range: 0.1106-0.1836 ppm), Cd (range: 0.1333-0.1273 ppm) and Mn (range: 0.1136-
0.1271 ppm). While Pb has the lowest concentration (range: 0.0472-0.0598 ppm). For all the site sampled the
heavy metal Ni was below detection level (BDL). From the results of heavy metals I-geo values, according to
Muller’s classification, all the sediment samples from the selected dams were unpolluted (class 0). The result for
the enrichment factor has shown that for all the selected dam sediment samples the heavy metals show
deficiency to minimal enrichment. Also based on the contamination factors for all sediment samples the heavy
metal Cd has a CF values range of 0.5430-0.6665 (~1), indicating that the sediment samples are moderately
contaminated with Cd. In contrast, the rest of the heavy metals exhibit low contamination in general. The value
of PLI ranges from 0.2408 to 0.4935, indicating unpolluted to moderate pollution. The Eri values for all
samples are all < 40, presenting low ecological risk. The results suggest that the sediment samples from the
selected dams in Katsina state has low contamination by the heavy metals evaluated.

In the present paper, the sodic soil samples were collected from the salt production area of Thakhauttaw, Hanlin, Sataung Gyi and Paline, Shwebo District, Sagaing Region. These samples were studied on the elemental analysis using the energy dispersive x ray fluorescence EDXRF spectroscopy. In order to evaluate the contamination status of metals, assessment indices such as metal pollution index MPI and enrichment factors EFs have been calculated by using the metal concentrations from the EDXRF results. The values of metal pollution index MPI for all samples were less than 1. This indicating the sodic soil was no significant of metal pollution. The results of enrichment factors show that Ca and Mn considerable enriched levels in the soil. According to health physics point of view, the overall study suggests that the sodic soil from salt production area were not metal contaminated and long term consumption cannot be cause potential health risks to consumers.

Determination of Heavy Metals in Boreholes, Hand Dug Wells and Surface Water ...Premier Publishers
Drinking water Quality is one of the most important concerns. The heavy metals level up to ppb levels in drinking water quality may cause severe health problems. In this study attempt was made to determine the concentrations of eight heavy metals in water samples taken in August 2016 from boreholes, hand dug wells and streams in some selected areas of Mubi North local government Adamawa state. These samples were subjected to analysis for eight elements (Zn, Fe, Ca, Na, Mg, Mn, Pb and Cd using Atomic Absorption Spectrophotometer (AAS). The concentrations of these metals in the study areas were compared with drinking water quality limits given by the World Health Organization (WHO). Na, Mg, Fe, Mn, Zn and Ca concentrations were found to range from 4.80-5.0, 0.06-2.6, 0.03-3.05, 0.04-0.80, 0.02-0.17, 20.49-35.6Mg/L respectively. The concentrations of Na, Mg, Ca, and Zn found in this study were lower than the permissible limit of WHO. While that of Fe in water sample from stream were found to be higher as compared with the WHO standard. Similarly the concentration of Mn in stream and borehole water samples were also higher.Cd and Pb were not detected in all the samples.
HEAVY METAL POLLUTION AND REMEDIATION IN URBAN AND PERI-URBAN AGRICULTURE SOILSchikslarry
Throughout the world, there is a long tradition of farming intensively within and at the edge of cities (Smit et al., 1996). However, most of these peri-urban lands are contaminated with pollutants including heavy metals, such as Cu, Zn, Pb, Cd, Ni, and Hg. The major sources of heavy metal contamination in agricultural soils are discharge of effluents from domestic sources, coal-burning power plants, non-ferrous metal smelters, iron and steel plants, dumping of sewage sludge and metal chelates from different industries. Once the heavy metals are released into soils, plants can absorb and bio-accumulate these heavy metals and thereby affect humans and animals’ health upon consumption (Seghal et al., 2014). Hence, there is a great need to develop effective technologies for sustainable management and remediation of the contaminated soils. There are conventionally physicochemical soil remediation engineering techniques, such as soil washing, incineration, solidification, vapour extraction, thermal desorption, but they destroy the plant productive properties of soils. Moreover, they are usually extremely expensive, limiting their extensive application, particularly in developing countries and for remediation of agricultural soils (Kokyo et al., 2014). Phytoremediation has been increasingly receiving attentions over the recent decades, as an emerging, affordable and eco-friendly approach that utilizes the natural properties of plants to remediate contaminated soils (Wang et al., 2003). Phytoremediation includes phytovolatilization, phytostabilization, and phytoextraction using hyper-accumulator species or a chelate-enhancement strategy. The future of this technique is still mainly in the research phase, and many different Hyperaccumulators and crops that can be cultivated in heavy metal contaminated are still being tested.
Opportunities and constraints of using the innovative adsorbents for the remo...Dr. Md. Aminul Islam
The presence of cobalt(II) in wastewater is an emergent concern because of its toxicity at elevated concentration.
Co(II) is a non-biodegradable, carcinogenic and mutagenic pollutant released from natural, industrial and
manmade sources. In recent years, the control of water that has been polluted with Co(II) has been an emergent
issue. The release of Co(II) into waterways is undesirable because ingestion of high levels of Co(II) may cause
severe health issues including cancer. The current review discusses the different adsorbents such as carbonaceous and activated carbon materials, nanosized metal oxides, low-cost natural materials, clay minerals and
nanocomposites employed by researchers to treat Co(II)-polluted water. The systems used have been assessed in
terms of overall Co(II) sorption capacity. Special emphasis has been given to the environmental conditions such
as contact time, solution pH, initial Co(II) concentration, temperature, and mineral dosage. Moreover, empirical
and surface complexation modeling (SCM) of the sorption systems is summarized. Natural materials, agricultural
waste materials, and bio sorbents exhibited outstanding Co(II) sorption performance. The current investigation
provides an overview of the state of the Co(II) removal studies performed by using various adsorbents.

Why Mining is an Environmental Evil.pptxNeutralWeeb
A presentation on how mining proves to be hazardous for our natural as well as human resources. In this presentation we explain underground mining, open pit mining etc with various case studies supporting the data.
This document discusses the environmental impacts of soil and sand mining. It notes that sand mining is increasing to meet demand but can cause significant environmental damage. Key impacts include degradation of water quality through acid mine drainage, heavy metal contamination, and increased turbidity. Groundwater levels also decline due to mining. Air quality and noise levels are negatively impacted by dust and machinery. Mining disturbs land use and soil quality through removal of vegetation and changing topography. The document provides examples of these issues occurring in various regions of India and discusses regulatory challenges of unchecked illegal sand mining.
International journal of science technologyMiftahur Rizqi
Sand is an important mineral for our society in protecting the
environment, where this practice of sand and soil mining is becoming an
environmental issue as the demand for sand increases in industry and construction.
Mining and its associated activities can be responsible for considerable
environmental damage. In this article we are discussing about the direct and indirect
impacts due to soil and sand mining to the environment in Indian regions. Pollution
of the water is evident by the colouration of water which in most of the rivers and
streams in the mining area varies from brownish to reddish orange. Low pH (between 2-
3), high electrical conductivity, high concentration of ions of sulphate and iron and toxic
heavy metals, low dissolved oxygen (DO) and high BOD are some of the physicochemical
and biological parameters which characterize the degradation of water quality.
Contamination of Acid Mine Drainage (AMD) originating from mines and spoils,
leaching of heavy metals, organic enrichment and silting by sand particles are major
causes of degradation of water quality.
1) Acid mine drainage from exposed sulfide minerals in mines poses serious threats to water resources, dissolving heavy metals and lowering pH levels severely impacting aquatic life.
2) Uncontrolled sand and soil mining degrades the environment through water pollution, loss of habitat, depletion of groundwater, and damage to agriculture and livelihoods.
3) Studies in India found mining-impacted areas had heavy metal concentrations in soil exceeding limits and acid mine drainage contaminating groundwater for long distances.
This document discusses geochemical applications for environmental monitoring and metal mining management. It summarizes that metal mining produces various solid wastes that can impact the environment if not properly managed, such as waste rocks and tailings. Acid mine drainage is a major environmental concern, as the oxidation of metal sulfides during mining can produce sulfuric acid and leach heavy metals. Geochemical analysis of mining wastes can help identify potential sources of contamination and inform appropriate prevention and monitoring plans to minimize environmental impacts from metal mining.
An analytical study of heavy metal concentration in soil of an industrial reg...Manoj Kumar Tiwari
Major generators of the industrial solid wastes are coal based thermal power plants and integrated iron and steel industries. A large amount of industrial solid wastes like fly ash and slag are yet to be utilized and still remains in the form of uncontrolled dumping sites in the study area. Leachate pollution should get appropriate attention as it may be a source of heavy and toxic metal in soil and it is possible to percolate and may lead to water pollution in the surroundings water sources. In the present investigation the soil samples were collected from the identified area for heavy metal analysis. The heavy metal pollution of the soil samples resulted that, concentration of certain heavy metals is above permissible limit. The heavy metals like Cr, Cd, Fe, Mn, and Pb, shows highest concentration, while metals such as Cu, Cd and Pb shows low concentration. The heavy metal pollution indicates that leachate produced by uncontrolled and unscientific disposal of industrial solid wastes contaminates soil samples of the identified area.

The effect of gas flaring on the rate of corrosion of metals within Egi kingdom was investigated
in this work. Surface water which has been exposed to gas flares, was taken from Ogbogu flow station in the Egi
kingdom of Ogba/Egbema/Ndoni Local Government Area of Rivers State Nigeria, and was used for this
experiment. The procedure involved soaking one set of the coupons of mild steel and copper in the water taken
from the gas flow station and another set in distilled water and kept for 14 days; after which the metals were
removed and weighed for weight loss as a result of the corrosive effect of both water. This process was repeated
for 56 days and various data obtained was analyzed using empirical correlation. Matlab was used for
computation and simulation. At day 42, corrosion rate for the flare zone water and distilled water were for mild
steel 3.332cm/days and 2.666cm/days and copper 2.562cm/days and 2.277cm/days respectively. The result
obtained showed a higher rate of corrosion for water taken from within the flare zone of Ogbogu Flow station

Health risks of heavy metals in selected food crops cultivatedAlexander Decker
This document summarizes a study that assessed heavy metal levels in soils and two commonly consumed food crops (cassava and plantain) in small-scale gold mining communities in Ghana. Soil samples contained heavy metals within permissible limits, though pollution load indices revealed significant metal loading. Heavy metal levels were higher in the food crops than soils. Lead, cadmium, zinc and copper levels in plantain, and lead, cadmium and zinc levels in cassava exceeded international safety standards. Analysis showed local inhabitants were at risk of long-term health effects from dietary exposure to these heavy metals.
Mining has several negative environmental impacts. It can cause acid mine drainage which releases toxic water. Mining also decreases air quality by releasing gases and particulate matter which impact human health. Heavy metals from mining contaminate soil and water sources. Mining activities like surface mining can cause erosion and disrupt habitats. Overall, mining disturbs the landscape and natural environment while also posing health risks to nearby communities.
This document summarizes the environmental impacts of mining. It discusses surface mining techniques like strip mining and mountaintop removal mining that remove soil and rock to access buried minerals. Underground mining is also covered. Key impacts include acid mine drainage that pollutes waterways, air pollution from mining emissions, heavy metal contamination of water and soil, erosion, and damage to wildlife habitats. Social impacts on communities like displacement and health effects are also outlined. The conclusion states that without proper remediation, the long-term costs of environmental damage from mining can be devastating.

The metals, which are required in a very minute amount and are considered toxic, are
termed as heavy metals. Researchers have widely investigated and studied these metals
due to their dangerous and harmful influence on health and the environment. Due to their
ability to accumulate and toxic nature these are addressed to be a vital source of environmental
contamination. Heavy metals have critically polluted the environment and its components.
This has severely damaged its abilities to promote life and provide its intrinsic
values. These are naturally available compounds and because of their anthropogenic origin
they are commonly found in various environmental domain. This results in deterioration of
the environment competence to support life and health of human, animals and plants
becomes threatened. This takes place because of bioaccumulation of these heavy metals in
the food chain which is a direct consequence of nondegradable state of the heavy metals.
The surroundings within which the human life exists is referred as the environment. It basically
comprises of the water, land, microorganisms, animal and plant life and the atmosphere
of the earth.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.
