摘要 为评估有机磷酸酯(organophosphate esters, OPEs)类阻燃剂污染引起的水产品质量安全风险,以广东汕尾红海湾海域近岸养殖和捕捞水产品为研究对象,采用气相色谱三重四级杆串联质谱法(Gas Chromatography-Tandem Mass Spectrometry, GC-MS/MS)对水产品中10种OPEs含量进行测定。结果表明:红海湾海域养殖水产品中∑10OPEs含量为(55.8±24.2)ng/g(干质量),显著高于捕捞水产品中的含量(20.5 ng/g±20.6 ng/g,干质量)(P<0.05);捕捞水产品中,底栖水产品中∑10OPEs含量(28.4 ng/g±22.6 ng/g,干质量)显著高于中上层水产品中的含量(7.4 ng/g±4.3 ng/g,干质量)(P<0.05);磷酸三(2-丁氧基乙基)酯[tris (2-butoxyethyl) phosphate, TBOEP]、磷酸三正丁酯(tri-n-butyl phosphate, TNBP)、磷酸三(2-氯异丙基)酯[tris (2-chloroisopropyl) phosphate, TCIPP]、磷酸三(2-氯乙基)酯[tris (2-chloroethyl) phosphate, TCEP]和磷酸三苯酯(triphenyl phosphate, TPHP)是红海湾海域水产品检出频率最高的OPEs化合物;养殖水产品和捕捞底栖水产品中主要OPEs污染物组成基本一致,含量最高的OPEs污染物依次为TCEP、TBOEP、TCIPP,而捕捞的中上层水产品中含量最高的OPEs污染物依次为TBOEP、TCIPP、TPHP,暴露评估显示,红海湾海域水产品中OPEs对不同年龄段男性和女性的非致癌风险和致癌风险均低于潜在风险阈值,健康风险可接受。研究表明,OPEs污染在养殖和捕捞水产品中普遍存在,所引起的健康风险水平尚在安全范围内,但随着OPEs消费量的持续增加,由其引起的水产品质量安全风险会越来越高,建议对水产品中OPEs污染情况进行持续跟踪调查。 In order to evaluate the quality and safety of fishery products caused by the contamination of organophos-phate esters(OPEs),contents of 10 types of OPEs were determined in fishery products including 7 species of fish cultured in cages and 16 species of wild fish collected from fishing ports in Honghai Bay by Gas Chromatography-Tandem Mass Spectrometry(GC-MS/MS).The results showed that the average contents of∑10OPEs were(55.8±24.2)ng/g(dry weight)in cultured species,significantly higher than those in wild fish(20.5 ng/g±20.6 ng/g,dry weight)(P<0.05).There was significantly higher content of∑10OPEs in demersal fish(28.4 ng/g±22.6 ng/g,dry weight)than in pelagic fish(7.4 ng/g±4.3 ng/g,dry weight)in the wild fish(P<0.05).Tris(2-butoxyethyl)phosphate(TBOEP),tri-n-butyl phosphate(TNBP),tris(2-chloroisopropyl)phosphate(TCIPP),tris(2-chloroethyl)phosphate(TCEP),and triphenyl phosphate(TPHP)were the organophosphate compounds with the highest frequency detected in the fishery products of Honghai Bay.The composition profiles of OPEs in cultured species were consistent with that in the demersal species,with the maximal levels of TCEP,TBO-EP,and TCIPP,while the main OPEs in captured pelagic fishery products were TBOEP,TCIPP,and TPHP,in that order.The results of the exposure assessment showed that the non-carcinogenic risks and carcinogenic risks of OPEs in fishery products in the Honghai Bay for males and females in different age groups were below the potential risk thresholds and the health risks were acceptable to date.The finding indicates that OPEs is prevalent in farmed and wild caught fishery products,and that the level of health risk posed is still within the safe range.However,as the usage of OPEs continues to increase,it is recommended that the contamination of fish products with OPEs be continuously monitored.
