Article
Microplastics (MPs) have been shown to act as sorbent phases and thus carriers of organic chemicals in the aquatic environment. Therefore, concerns exist that MP ingestion increases the uptake and accumulation of organic chemicals by aquatic organisms. However, it is unclear if this pathway is relevant compared to other exposure pathways. Here we c...
Article
Microplastic (MP) ingestion has been shown for various organisms; however, knowledge of their potential adverse effects on freshwater invertebrates remains limited. Here we assessed the ingestion capacity and the associated effects of polyester fibers (26‐5761 µm) and car tire particles (25‐75 µm) on freshwater invertebrates under acute and chronic...
