“…Other species used were unicellular algae, freshwater crabs and snails, bacteria, protozoa, and vascular plants [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ] ( Figure 2 B). As for the polymer type, polystyrene (PS) is the most studied polymer (70%), as it also stands as the third most abundant polymer in the environment, after polyethylene (PE) and polypropylene (PP) ( Figure 2 C) [ 36 ], which gives it an environmental relevance. Following PS, PE is the second most used polymer (15%) for investigating the influence of NMPs on the bioaccumulation of contaminants.…”
