英文摘要:
The concentrations and spatial distributions of hexabromocyclododecane (HBCDD) and tetrabromobisphenol A (TBBPA) were measured in tree bark from different functional areas of Shanghai. Sigma HBCDD (sum of alpha-, beta-, and gamma-HBCDD) concentrations ranged from 1.2 x 10(2) to 6.6 x 10(3) ng g(-1) lw (median 5.7 x 10(2) ng g(-1) lw) and TBBPA concentrations ranged from 48 to 7.2 x 10(4) ng g(-1) lw (median 2.8 x 10(2) ng g(-1) lw). The concentrations of Sigma HBCDD and TBBPA all followed the order of industrial areas > commercial areas > residential areas. The mean percentage of alpha-HBCDD in bark samples (44%) from Shanghai was higher than that in technical HBCDD products, but comparable with that in air. The concentrations of TBBPA and individual HBCDD diastereoisomers between industrial areas and commercial areas were correlated. Based on the concentrations of HBCDD in the bark, the corresponding atmospheric HBCDD concentrations were estimated. Compared with the published data for HBCDD in urban air, the estimated atmospheric HBCDD concentrations in Shanghai had a relatively high level, and more attention should be paid to the pollution status of HBCDD in Shanghai.
