摘　　要：Benzothiazoles(BTHs)and benzotriazoles(BTRs)are an important group of industrial chemicals.Due to large scale and long-term applications,they have been released to various environmental media,including indoor dust,and subsequently elicited a variety of toxic effects.In this study,the concentrations and composition profiles of BTHs and BTRs in indoor dust from Suizhou and Beijing,China,were investigated.The median concentrations ofΣ_(6)BTHs in indoor dust samples from Suizhou and Beijing were 133 and 439 ng/g dw,respectively,whereas theΣ5BTRs concentrations from Suizhou and Beijing were 28.4 and 40.1 ng/g dw,respectively(dw=dry weight).BTH,2-OH-BTH,1-H-BTR,and 5-Me-1-H-BTR were the predominant compounds in the dust.Human exposure to such chemicals was further evaluated.The intake for the population in Suizhou(0.163–0.939 ng/kg bw/day)and Beijing(0.0347–0.200 ng/kg bw/day)was minor(bw=body weight).The obtained results in this study will be able to add insight into human exposure to BTHs and BTRs.This study will help to identify the behavior and fate of BTHs and BTRs in the environment,and thus to scientifically assess their risk of exposure.
