TL;DR: The hazard model indicates that much of the Indus Plain is likely to have elevated arsenic concentrations, although the rest of the country is mostly safe, and there is an urgent need for verification and testing of all drinking water wells in the Indu Plain, followed by appropriate mitigation measures.

TL;DR: In this paper, the authors evaluated the groundwater quality of Sialkot, an industrial city of Pakistan, using water samples collected from 25 localities during October-November 2005 and compared the results with standard guidelines of World Health Organization (WHO) and Pakistan Standard Quality Control Authority (PSQCA) for groundwater quality.

TL;DR: The spatial patterns of selected dust-borne trace elements alongside the river Indus Pakistan, their relation with anthropogenic and natural sources, and the potential risk posed to human health are assessed to contribute towards the environmental management of trace metal(s) with potential risk for human health throughout Pakistan.

TL;DR: The relationship of paired dust and nail samples was investigated and associations were found for As-nail and soil organic carbon density and SCC in each studied zone, evidencing the dust exposure as an important source of arsenic contamination in Pakistan.

TL;DR: The acute ecological risks for fish associated with the levels of OCPs are considered as negligible and more studies are recommended to evaluate the chronic ecological risks to other riverine-associated aquatic and terrestrial species as well as human health risks to the POPs exposure through food chain transfer in forthcoming years.
