Effects of polystyrene nanoplastics and copper on intestinal tissue structure, biochemical indexes, and intestinal microflora of the Chinese mitten crab (Eriocheir sinensis)

Effects of polystyrene nanoplastics and copper on intestinal tissue structure, biochemical indexes, and intestinal microflora of the Chinese mitten crab (Eriocheir sinensis).This study indicates that Eriocheir sinensis may regulate the combined toxicity of NPs and Cu through alterations in the intestinal microbiota, providing a potential reference for elucidating the mechanisms of joint toxicity of NPs and Cu in aquatic species.
