英文摘要	Microplastics have aroused great concern for their potential threats to marine organisms. This study investigated the interaction between three sizes of microplastics (0.5, 2, and 10 μm) and the marine copepod Pseudodiaptomus annandalei under two different microalgae concentrations (1 × 103 and 1 × 105 cells/mL). The results revealed that low microalgae supply increased microplastic ingestion through enhancing the encounter rates, and moreover increased the retention time of 0.5 μm microplastics. When the microalgae concentration was 1 × 103 cells/mL, 0.5 μm microplastics could be observed in the copepods after depuration in clear seawater for 24 h, but almost totally excreted at 1 × 105 cells/mL of microalgae. In addition, 0.5 μm microplastics induced significant effects on the ingestion of microalgae by P. annandalei both after 24 h of exposure and depuration. These results suggest that low microalgae availability may increase the ingestion and retention of microplastics in marine copepods, which might increase the ecological risk of microplastics. © 2020 Elsevier Ltd
