Abstract: The pollution of microplastics in the environment has attracted global attention.Reports and studies on microplastics emerge one after another, especially the impact of microplastics on the water environment.As a new persistent pollutant in water environment, microplastics will inevitably affect the environmental behavior of microalgae.Microalgae, as a primary producer, plays an important role in aquatic ecosystem.In this paper, we systematically summarized the domestic and foreign research progress on microplastic's effect on microalgae, and briefly analyzed of the impact of different concentration, size and surface charge of microplastic on the environment behavior of microalgae.Then we analyzed joint toxicity of microplastic and other toxic pollutants to microalgae, and summarized the study path on impacts of microplastics on microalgae.

Key words: microplastics; microalgae; primary producer; ecotoxicology;
