Objective : The purpose of this study was to estimate the levels of Suspended Particulate Matter (SPM) in ambient air within Mukula mine and the potential risks to mineworkers and inhabitants of the adjoining Mukula community's health. Methods : An SPM was used to measure the levels of particulate matter (PM10) in and around the mining site. One-way Analysis of Variance (ANOVA) was used to dete...

To develop a quantitative exposure-response relationship between concentrations and durations of inhaled diesel engine exhaust (DEE) and increases in lung cancer risks, we examined the role of temporal factors in modifying the estimated effects of exposure to DEE on lung cancer mortality and characterized risk by mine type in the Diesel Exhaust in Miners Study (DEMS) cohort, which followed 12,3...

This study was designed to investigate heavy metal (Cu, Zn, Pb, and Cd) contamination levels of soils, vegetables, and rice grown in the vicinity of the Dabaoshan mine, south China. The concentration of Cu, Zn, Pb, and Cd in paddy soil exceeded the maximum allowable concentrations for Chinese agricultural soil. The heavy metal concentrations (mg kg(-1), dry weight basis) in vegetables ranged fr...

Hydrographically Bolivian Poopó Lake is located in the basin of Desaguadero River and it has over a dozen main tributary rivers and other smaller rivers with lower flow. The mine water discharge from the abandoned and current mining activities polluted these rivers by carrying heavy metals, dissolved and suspended solids which in turn polluted the Poopó Lake which is considered as an important ...

METHODS Mines were divided in four geographic zones, and participants were selected by stratified cluster sampling technique. A total of 513 subjects were included in final study which were alienated among the four a...

a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...

over Population movement has long been identified as a factor in the spread of HIV throughout southern Africa. Today, migrant workers remain a key population to target for HIV prevention efforts not only because of their role in its transmission, but also because of their own vulnerability to the disease as a result of high-risk sexual behavior.1 In South Africa, mine workers comprise a large n...
