Human Arsenic exposure via dust across the different ecological zones of Pakistan.

The present study aims to assess the arsenic (As) levels into dust samples and its implications for human health, of four ecological zones of Pakistan, which included northern frozen mountains (FMZ), lower Himalyian wet mountains (WMZ), alluvial riverine plains (ARZ), and low lying agricultural areas (LLZ). Human nail samples (N=180) of general population were also collected from the similar areas and all the samples were analysed by using ICP-MS. In general the higher levels (p<0.

Arsenic levels from different land-use settings in Pakistan: Bio-accumulation and estimation of potential human health risk via dust exposure.

The present study aims at assessing arsenic (As) levels in outdoor dust and human exposure risks at different land use setting (i.e., rural, industrial, urban) from Punjab, Pakistan.
