由于苯系物对海洋生态系统的毒性作用,且在生物体内的代谢存在物种差异,为探索典型苯系物在贻贝体内潜在的代谢解毒途径及其代谢物,本文通过室内模拟苯系物暴露实验,采用UPLC-Q-TOF-MS技术,结合 Waters UNIFI数据信息系统,对苯、甲苯和二甲苯研究在贻贝体内产生的代谢物进行质谱分析.结果表明,苯、甲苯和二甲苯在贻贝体内分别产生了 6种苯代谢物、9种甲苯代谢和8种二甲苯代谢物,代谢途径有水合、还原、去饱和、氧化、硫酸化、二氢二醇、甲基化、葡醛酸结合反应等.其中二甲苯代谢物X-7是DPMA的同分异构体,其他苯系物的代谢产物为首次报道.本研究获得的苯系物在贻贝体内的代谢解毒途径和产生的代谢产物信息、开发的苯系物代谢物UPLC-Q-TOF-MS分析方法,丰富了海洋生态环境监测体系,并为我国近岸海洋生态环境安全评估提供理论依据和数据参考.
Identification of Benzene Series Metabolites in Mussels by UPLC-Q-TOF-MS
Due to the toxic effect of benzene series on marine ecosystem and species differences in the metabolism of organisms,in order to explore the potential metabolic detoxification pathway and metabolites of typical benzene series in mussels,the metabolites produced by benzene,toluene and xylene were identificatied by UPLC-Q-TOF-MS with Waters UNIFI data information system.The results showed that benzene,toluene and xylene produced 6 benzene metabolites,9 toluene metabolism and 8 xylene metabolites in mussels,respectively,with metabolic pathways of hydration,reduction,desturation,oxidation,sulfation,dihydrodiol formation,methylation,glucuronidation,etc.Among them,the xylene metabolite X-7 is the isomorphism of DPMA,and the metabolites of other benzene series are the first report.The metabolic detoxification pathway and metabolites of benzene series obtained in mussels,and the developed UPLC-Q-TOF-MS analysis method,have enriched the Marine ecological environment monitoring system and provided theoretical basis and data reference for the safety assessment of offshore Marine ecological environment in China.
