Liquid-dominated hydrothermal reservoirs, which contain saline fluids at high temperatures and pressures, have a significant potential for contamination of the environment by heavy metals. The design of the power conversion cycle in a liquid-dominated geothermal plant is a key factor in determining the impact of the installation. Reinjection of the fluid into the reservoir minimizes heavy metal...

INTRODUCTION: This paper describes selected findings from an interdisciplinary research project funded by the UK Department for International Development (January 2000 to April 2003) which was carried out in Delhi and Varanasi by Imperial College, London in partnership with Srishti; Delhi University; Banaras Hindu University, Varanasi; Development Tracks, New Delhi and the Indian Agricultural R...

During the last few decades, heavy metal contamination of biotic component of environment has attracted the attention of many investigators. The main reason of these researches based on the heavy metal concentration may have a potential hazard in our food chain after a long period of procrastination. Using biological materials in the determination of environmental pollution as indicators is a c...

The phenomenon of metal distribution and redistribution due to contamination is becoming interesting in the literature. In this study, the distribution of Cd, Cu, Pb and Zn were determined in different parts (root, byssus stem, two regions of byssal threads [proximal and distal] and attachment plaque) of the byssus of the green-lipped mussel Perna viridis collected from a metal-contaminated sit...

Background: The effects of trace elements on human health and the environment gives importance to the analysis of heavy metals contamination in environmental samples and, more particularly, human food sources. Therefore, the current study aimed to predict arsenic and heavy metals (Cu, Pb, and Zn) contamination in the groundwater resources of Ghahavand Plain based on an artificial neural network...

1 www.ijeas.org  Abstract— Soil contamination from industrial effluents and mining activities is a widespread concern all over the world. Generally soil act as the buffer zone between atmosphere and underground water, thus soil contamination creates a serious threat to soil and to the surrounding biosphere. This research program is aimed to make an in-depth investigation about the remediation ...

this study was carried out to 1. determine spatial variations of heavy metal deposition in agricultural soils of two rural communities (ouledbouaicha and tazakourte) of about 5790 ha in a mining area near marrakech city in morocco; 2. to assess the extent of metallic pollution generated by the mining activity and; 3. to identify the key mechanism responsible for this contamination and its relat...

SUMMARY Though cadmium has come into widespread use only relatively recently it is quite likely that for many countries this highly toxic metal has been causing food poisoning. Even minute amounts of cadmium are sufficient to cause poisoning and since the metal is soluble in organic acids; It easily enters food stuffs. The extreme danger resulting from ingestion of cadmium in food was high lig...
