Toxic metal(loid) speciation during weathering of iron sulfide mine tailings under semi-arid climate
Toxic metalliferous mine-tailings pose a significant health risk to ecosystems and neighboring communities from wind and water dispersion of particulates containing high concentrations of toxic metal(loid)s (e.g., Pb, As, Zn). Tailings are particularly vulnerable to erosion before vegetative cover can be reestablished, i.e., decades or longer in semi-arid environments without intervention. Meta...
Two soil sample series were collected from 7 contaminated sites situated along a transect from the pollutant source, Zlatna copper ore-processing plant, and analyzed using different analytical methods. The soils collected in 1998 were analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after extraction with DTPA for trace metals and those collected in 1999 were analyze...
Lung cancer mortality was examined in a cohort of 4393 men employed at a zinc-leadcadmium smelter. There was an excess oflung cancer (overall SMR = 124-5, 95% confidence interval 107-144) which was particularly evident for those employed for more than 20 years. A statistically significant trend in SMRs with increasing duration of employment was apparent. Quantitative estimates of exposure to ca...
An approach for assessing the inhalation bioaccessibility of Pb in the PM10 size fraction is presented, using an in vitro simulated epithelial lung fluid to represent the extracellular environment of the lung. The developed inhalation bioaccessibility method (IBM) is applied to a range of urban surface soils and mining wastes obtained from Mitrovica, Kosovo, a site where impacts upon human heal...
Abstract Indonesia’s copper ore has a contribution of 3% in the world’s needs and rank 5th largest export mining materials after briquette, kerosene, coal, crude oil. According to Mineral Coal Mining Law Number 4 2009 that raw products have been prohibited be exported including due increasing value mineral products. Thus, it would affect current shipment, which should firstly processed by smelt...
