A field of growing interest in environmental health is that of lead speciation, the study of the various chemical forms of lead. Different lead compounds have different solubilities, which in turn affect bioavailability. Descriptions of lead exposure such as concentrations in air or settled dust are telling quantities, but can only relate part of the story. A variety of biological and geochemic...

this study was aimed to investigate the effects of environmental pollution with heavy metals from ferro-nickel smelter on aminolevulinic acid dehydratase (alad) activity, and to analyze the blood lead level of feral pigeon ( columba livia ) in ferro-nickel smelter courtyard in drenas city, republic of kosovo. for this purpose, twenty specimens of feral pigeon (20 birds, males and females), were...

Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around pointsources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna. This thesis focuses on the effects on pied flycatcher populations o...

Process modeling today is an integral part of process development and design, operation optimization, process control, business evaluation and decision-making. This paper reviews the application of process modeling and simulation in copper metallurgy and discusses its further development, i.e. an intelligent system for smelter. A concept of future smart smelter that is an integration of intelli...

There are over 3,000 sites across the United States contaminated wtth lead. Techniques to remediate these sites include standard stabilization/disposal technologies, reclamation of lead using secondary lead smelters, soil washing, and biological removal technologies. Through a Cooperative Agreement with the U.S. Environmental Protection Agency’s Risk Reduction Engineering B secondary Laboratory...

An increased mortality from lung cancer, cardiovascular disease, haematolymphatic malignancy and cirrhosis of the liver has been reported among smelter workers and others exposed to arsenic. This study uses the case-referent (case-control) technique and is concerned with workers in a copper smelter in a complex work environment, characterised by the presence of trivalent arsenic in combination ...
