The occurrence of polybrominated diphenyl ether (PBDE) contamination in soil, water/sediment, and air
2019
As a kind of brominated flame retardants (BFRs), polybrominated diphenyl ethers (PBDEs) are extensively used in different types of electronic equipment, furniture, plastics, and textiles. PBDEs are ubiquitous environmental contaminants that may impact human health and ecosystems. Here we highlight recent findings on the occurrence, contamination status, and transport of PBDEs in soil, water/sediment, and air. Four aspects are discussed in detail: (1) sources of PBDEs to the environment; (2) occurrence and transport of PBDEs in soil; (3) PBDEs in aquatic ecosystems (water/sediment) and their water–sediment partitioning; and (4) the occurrence of PBDEs in the atmosphere and their gas–particle partitioning. Future prospects for the investigation on PBDEs occurrence are also discussed based on current scientific and practical needs.
