[Elemental Characteristics and Health Risk Assessment of Heavy Metals in Atmospheric PM in a Suburb of Zhuhai City].

To investigate the characteristics, sources, and health risks of trace heavy metals in fine particles, PM samples were collected at a suburban site of Zhuhai in the Pearl River Delta Region. Fifteen elements in the PM were analyzed by an X-ray fluorescence method. The results showed that the total mass concentrations of crustal elements (Al, Si, Ca, Fe, and Ti) in a typical month during spring, summer, autumn, and winter were (708±213), (645±269), (1155±503), and (1466±492) ng·m, respectively, while the total mass concentrations of the rest of the trace elements (Ba, Co, Cr, Cu, Mn, Ni, Pb, Sb, V, and Zn) were (271±124), (163±87.

Legacy and Currently Used Organic Contaminants in Human Hair and Hand Wipes of Female E-Waste Dismantling Workers and Workplace Dust in South China.

Legacy organic contaminants, such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), and several currently used organic contaminants, such as novel brominated retardants (NBFRs), organophosphate flame retardants (OPFRs), and Dechlorane Plus (DPs), were measured in the segmented hair and hand wipes of e-waste dismantling workers and in the dust from their workplace in an e-waste recycling site in South China to assess the accumulation and sources of organic contaminants in the hair shaft. The median concentrations of DPs, PBDEs, NBFRs, PCBs and OPFRs in hair samples were 23.5, 154, 156, 349, and 371 ng/g, respectively.
