摘要

微塑料是多种污染物，它们通过海洋生物的转移会影响健康。然而，尽管进行了大量研究，但跨多个营养水平的微塑料量化尚不完整。在这里，摄入，保留，净化和转移的环境相关聚酯（PEST）微塑料，与增塑剂邻苯二甲酸双（2-乙基己基）（DEHP）作为一种共污染物，报告了三种珊瑚礁物种。暴露的桡足类（Parvocalanus crassirostris）、粘壳虾（Mysida）和月濑鱼（Thalassoma lunare）摄入（21.33±15.94个PEST个体−1）、保留（48 h）和清除（5.77±1.27个PEST个体−1）PEST。从桡足类到虾类分别增加14.6倍和4.3倍。所有生物均表现出PEST生物富集，但PEST生物放大仅发生在对虾中。DEHP对桡足类动物对PEST的摄取有正向影响，但对PEST的转移没有影响。害虫在整个食物链中的转移，加上物种特异性的生物浓度和生物放大动力学，增强了对微塑料命运的理解，并为生态影响评估提供了信息。

Trophic transfer of polyester microfibres across a multi-level marine food web

Microplastics are multifarious contaminants and their transfer by marine organisms can impact health. Yet, despite considerable research, microplastic quantification across multiple trophic levels is incomplete. Here, ingestion, retention, depuration and transfer of environmentally relevant polyester (PEST) microplastics, with plasticising bis(2-ethylhexyl) phthalate (DEHP) as a co-contaminant, is reported for three reef species. Exposed copepods (Parvocalanus crassirostris), mysid shrimps (Mysida) and moon wrasse fish (Thalassoma lunare) ingested (<21.33 ± 15.94 PEST individual⁻¹), retained (<48 h), and depurated (<5.77 ± 1.27 PEST h⁻¹) PEST. Trophic transfer was observed as a 14.6-fold (copepods to shrimps) and 4.3-fold (shrimps to fish) increase of PEST. All organisms demonstrated PEST bioconcentration, PEST biomagnification only occurred in shrimp. DEHP positively influenced PEST intake by copepods, yet had no impact on PEST transfer. Demonstrated PEST transfer across this food chain, coupled with species-specific bioconcentration and biomagnification dynamics, enhances understanding of microplastics fate and informs ecological impact assessments.

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
