Evaluating heavy metals contamination in campus dust in Wuhan, the university cluster in Central China: distribution and potential human health risk analysis

The potential health risk of heavy metals (HMs) in campus dust may threaten the thousands students, teachers, and their families Wuhan, university cluster Central China every day. In this research, pollution characteristics with HMs was first time presented from canteen, playground, dormitory, school gate to date. average concentration dusts ranked Pb (83.5 mg kg−1) > Cu (70.2 Zn (47.2 Cr (46.0 Ni (22.7 As (15.2 Cd (3.38 kg−1). would more likely accumulate dormitory canteen dust. downtown area, Zn, As, had been preliminarily identified fossil fuel combustion natural geochemical processes. source cooking traffic transportation. reflect contributions soil weathering. No significant non-carcinogenic risks were found students or teachers Their children exposure when eating playing on walking around gate.
