Abstract:In order to evaluate the contamination and health risk of heavy metals from atmospheric deposition in Anqing, samples of atmospheric deposition were collected from 48sampling sites respectively and their concentrations of heavy metals were determined. The results showed that the average contents of Cu, Zn, Pb, Ni, Cr, As, Cd were 134.1, 640, 128.9, 55.4, 128.7, 63.9, 2.98mg/kg, respectively. According to the results, the enrichment factor score of Ni, Cr was close to 1, belonged to slightly enriched, while the enrichment of Cu, Pb, As was more serious, and Zn, Cd were extremely enriched, each enrichment factors were reach 10.25 and 29.53. The assessment results of geo-accumulation index of potential ecological risk indicated that the pollution of Cd in the atmospheric deposition of Anqing was classified as extreme degree and the average geo-accumulation index was 5.07, and that of Cu, Pb, As were between moderate and extreme degrees, and Ni, Cr as slightly uncontaminated, and Zn belonged to moderate pollution, some areas reach serious pollution. Health risk assessment indicated that the heavy metals in atmospheric deposition were mainly ingested by human bodies through hand-mouth ingestion. The order of non-cancer hazard indexes of heavy metals was As > Cr > Pb > Cu > Cd > Ni > Zn. The hand-mouth ingestion of As has reached 2.72 significantly exceeded the limits 1, easy to affect children's health. Other metals didn’t exceed the limit of risk, and were not harmful for people's health. Elements such as Ni, Cr, As, Cd content in dust do not cause any cancer risk by inhalation.
