Article Preview

The human risks of As and heavy metals (Cu, Ni, Cr, Pb, Cd and Hg) in fine particulate matter (PM2.5) in Xining, China is investigated here in this study. Cu, As and Pb are the most abundant elements in stationary monitoring station for atmospheric pollution and mountain Najia. As, Pb and Cr are the most abundant elements in the park of organisms and Xining Special Steel between the studied metals and metalloids in PM2.5. Pb and As showed a higher bio-accessibility. It has been shown that the carcinogenic risks of As, Cd, Cr and Ni in PM2.5 via dermal contact and inhalation exposure are within the acceptable level (<1×10-4) for both children and adults, but there is a potential carcinogenic risk posed by Pb via ingestion. As for non-carcinogenic health risks, the hazard index values for all the studied elements suggested no health risks via ingestion and dermal contact, but a potential one via inhalation of adults. Values of hazard quotient and hazard index indicated the non-carcinogenic risks from the studied metals and metalloids to children via ingestion, dermal contact and inhalation pathways during heating period in Xining given the present air quality .
