lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. in this paper, the environmental problems of lead and zinc production in calcimin plant are expressed and life cycle assessment of this plant is assessed. the data regarding the amount of induced global warming and pollution, acidification, and depletion...
Lead (II) ion adsorption capacity of clinoptilolite from artificial polluted tap water was investigate in this study. For the experimental studies, Clinoptilolite mineral which is 25-140 mesh size was used by activating with HCl, and lead ion removal efficiencies were examined. Experiments were studied under laboratory batch conditions were run at different pH values, temperatures. The highest ...
Aerosol samples of PM10 particulates were examined with particle-induced X-ray emission (PIXE and micro-PIXE ), inductively coupled plasma-mass spectrometry, and X-ray absorption fine structures (XAFS) to investigate atmospheric Pb concentrations and its chemical species and to decide the source assignment. From the elemental analyses, lead concentrations were averaged at 369 and 237 ng.m-3 in ...
Frank lead poisoning was found in some inhabitants of houses in the Scottish Highlands, exposed to soft water and lead-lined drinking water tanks. Further investigations were carried out on the clinical and metabolic effects of lead acquired by drinking soft domestic water from lead plumbing systems in 23 Glasgow households. The lead content of water from cold taps was up to 18 times the upper ...
OBJECTIVE To determine the blood lead levels and trace elements (copper and manganese) in traffic police constables in Islamabad in order to assess the effects of environmental pollution on the levels of metals in body fluids. METHODS Blood samples were collected from 47 male traffic police constables, 21 to 45 years of age, posted in different areas of Islamabad and controlling traffic from ...
