Abstract

Microplastics (MPs) have unique toxicokinetic (TK) processes that differ from those of soluble pollutants. This study investigated the ingestion, migration, accumulation, and clearance of environmental aging MPs in the Japanese swamp shrimp (Macrobrachium nipponense). The concentrations of plastic additives and personal care products adsorbed onto MPs in natural river water were determined, and TK models for MPs and MPs-loaded pollutants were developed. Results showed that the formation of surface biofilms and alterations in the distribution of MPs in waters caused by environmental aging affect MPs bioavailability, which is mainly related to the feeding habits of shrimp. The decrease in MPs particle size caused by biological digestion and the increase in the number of oxygen-containing functional groups caused by environmental aging affect the TK process of MPs. The TK model of MPs-loaded pollutants revealed the cleaning effect of shrimp on pollutants adsorbed onto MPs during swallowing and spitting MPs. This cleaning effect significantly increases the bioavailability of MPs-associated pollutants in aquatic environments. This study provides a new perspective for understanding the interactions between environmental MPs and their associated pollutants in aquatic ecosystems.

日本鲭体内微塑料的毒物动力学及其对所含污染物生物利用率的影响。
微塑料(MPs)具有不同于可溶性污染物的独特毒物动力学(TK)过程。本研究调查了日本沼虾(Macrobrachium nipponense)对环境老化微塑料的摄取、迁移、积累和清除。研究测定了天然河水中吸附在 MPs 上的塑料添加剂和个人护理产品的浓度,并建立了 MPs 和负载 MPs 的污染物的 TK 模型。结果表明,环境老化导致的水体表面生物膜的形成和 MPs 分布的改变会影响 MPs 的生物利用率,这主要与对虾的摄食习性有关。生物消化引起的 MPs 粒径减小和环境老化引起的含氧官能团数量增加会影响 MPs 的 TK 过程。MPs负载污染物的TK模型揭示了对虾在吞咽和吐出MPs过程中对吸附在MPs上的污染物的清洁作用。这种清洁效应大大提高了 MPs 相关污染物在水生环境中的生物利用率。这项研究为了解水生生态系统中环境 MPs 及其相关污染物之间的相互作用提供了一个新的视角。
