Advantages

Micron-sized microplastics combined with phenanthrene reduced CAT, GST, and SOD activities in T. tubifex

Microplastics and phenanthrene decreased the abundance of Proteobacteria, Fusobacteriota, and Bacteroidetes in the gut of T. tubifex

Microplastics reduced the abundance of Bacteroidetes, Acidobacteria, and Proteobacteria in sediment

Phenanthrene addition increased the abundance of salicylate hydroxylase enzyme related to PAHs metabolism
