广西北部湾典型水产品中有机磷酸酯的生物富集特征和食用风险评估
Accumulation and dietary risk assessment of organophosphate esters in typical aquatic products of the Beibu Gulf
摘要
Abstract
This study aims to investigate the bioaccumulation characteristics and dietary risks of organophosphate esters(OPEs)in aquatic products from the natural environment of the Beibu Gulf.A total of 65 samples from six species were collected from nearshore and estuarine areas during summer and winter.The concentrations of OPEs were quantified using gas chromatography-tandem triple quadrupole mass spectrometry(GC-MS/MS).The results revealed the presence of 11 OPEs in aquatic products,with concentrations significantly higher in winter[(127±101)ng/g dw]compared to summer[(38.5±28.6)ng/g dw].Fish exhibited lower concentration of OPEs than benthic organisms across both seasons.Seasonal compositional patterns were consistent,dominated by tris(2-chloroisopropyl)phosphates(TCIPPs)and tris(2-chloroethyl)phosphate(TCEP).Chlorinated OPEs(Cl-OPEs)exhibited higher bioaccumulation potential than Alkyl-OPEs,with tris(1,3-dichloroisopropyl)phosphate(TDCIPP)and trihexyl phosphate(THP)obviously bioaccumulated in all aquatic products.Key factors influencing bioaccumulation included metabolic capacity,feeding habits,and habitat conditions.Dietary risk assessment showed hazard quotients(Qh)below 1 for all age and gender groups,indicating low dietary risk.This study advances the understanding of OPEs contamination in the Beibu Gulf aquatic products and provides a scientific basis for ecological protection and food safety management.关键词
