Pollution Characteristics of PBDEs in Indoor Dust and Human Exposure: Prospects of Research
Abstract：Polybrominateddiphenyl ethers (PBDEs) have been widely used in commercial products as flame retardants.They can be released from a variety of commodities through volatilization and abrasion,and high brominated congeners can transformed into low brominated congeners through debromination in indoor environment.Thus PBDEs have been widely detected in various environmental media and led to long-term low-dose human exposure,becoming one of the major threats to human health.Based on the recent research of PBDEs in indoor dust,this paper summarized the pollution characteristics of PBDEs in indoor dust and the corresponding human exposure.Results suggested that PBDEs contamination varied greatly in different types of indoor environmental,and even in the same indoor environment,spatial variation were apparent;data for temporal distribution of PBDEs in indoor dust were limited;the influence of particle size on distribution of PBDEs in indoor dust and human exposure was causing more and more attention,and the effect of dust fraction selection on determination of PBDEs in indoor dust and its function mechanism was in urgent need to be discovered.Furthermore,prospects of further research were reviewed in terms of PBDEs pollution control and management.
