摘要:近海环境中的微塑料污染问题已成为全球性的环境问题，引起了世界范围内的广泛关注。微塑料不仅能够对生物造成物理损伤，而且塑料中的添加剂如邻苯二甲酸酯、双酚A、多溴二苯醚等也会随着塑料的风化而浸出进入环境，对生物产生毒害，同时，微塑料还能吸附海洋环境中的其他污染物，从而对生物产生联合毒性作用。本文综述了微塑料与持久性有机污染物的联合作用，结果表明聚苯乙烯微塑料能够吸附海水中的持久性有机污染物如多环芳烃、多氯联苯、有机氯农药滴滴涕，从而可能导致这些污染物在海洋生物组织中富集，对人类健康存在直接或间接危害。最后本文在总结前人研究的基础上，对未来微塑料与农药污染联合毒性作用的研究方向做了简要分析和展望。

Abstract:Microplastic pollution has become a global environmental issue. Besides the direct toxicity of microplastics to marine organisms, the additives in microplastic such as phthalate, bisphenol A, polybrominated diphenyl ethers，can leach from the plastics and cause toxicity to the organisms. Moreover, microplastics can result in combined toxicological effect to marine organisms due to interactions between microplastics and persistent organic pollutants (POPs). Therefore, this paper summarized the combined effect of microplastics and POPs in marine environment. The results showed that polystyrene derived microplastic can adsorb polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and organochlorine pesticides (such as dichlorodiphenyltrichloroethane) in seawater, resulting in bioaccumulation of these additives in marine organisms and posing risks to human health. Furthermore, more studies are needed to understand the combined toxicological effect of microplastics and pesticides in oceans.
