英文摘要	Trophic transfer of hexabromocyclododecane (HBCD) was investigated in both the terrestrial and aquatic food webs from an e-waste dismantling region in East China. The mean Sigma 3HBCD concentrations in the terrestrial species varied from 0.91 (0.16-1.85) ng g(-1) lipid weight (lw) in dragonflies (Pantala flavescens) to 40.3 (22.1-51.1) ng g(-1) lw in rats (Rattus norvegicus). The isomeric profile indicated that alpha-HBCD presented a decreasing trend along the trophic level (TL) (from 97.2% to 16.3% of Sigma(3)HBCDs), while gamma-HBCD showed a reverse trend (from 2.8% to 73.6% of Sigma(3)HBCDs). The trophic magnification factor (TMF) derived from the slope of the regression line between TLs and ln-transferred Sigma(3)HBCDs was 0.10, suggesting a trophic dilution of HBCD in the terrestrial food web. By contrast, in the aquatic species, Sigma 3HBCD concentrations varied from 5.02 (3.5-6.55) ng g(-1) lw in apple snails (Ampullaria gigas spix) to 45.9 (14.9-67.8) ng g(-1) lw in grass carps (Ctenopharyngodon idellus). alpha-HBCD was the dominant isomer, followed by gamma-HBCD in the majority of species. A positive linear relationship was observed in the plots of ln Sigma(3)HBCDs versus TLs (R-2 - 0.81, p - 0.06). The TMF for Sigma(3)HBCDs was 6.36, indicating a trophic magnification of HBCD in the aquatic food web. Although these results demonstrated the distinct trophic transfer of S3HBCDs in different ecosystems, further research is needed to eliminate the uncertainty of the tendencies, due to the non-significant relationship and limited species.
