Submicron-size-dependent toxicity of microplastic-antibiotic mixtures in Chlorella pyrenoidosa.
As an emerging contaminant, the co-presence of microplastics (MPs) of multiple sizes can exacerbate ecological risks. This study investigated the individual and combined toxicity of three-sized MPs (0.2, 0.3, 0.4 μm) and three macrolide antibiotics on Chlorella pyrenoidosa. In a single exposure scenario, 0.4 μm polysty...
