Fig. 2From: Toxic effects on enzymatic activity, gene expression and histopathological biomarkers in organisms exposed to microplastics and nanoplastics: a reviewPercentage of studies under the effects of MPs/NPs on enzymatic activity/gene expression/histopathology of organisms in 2016 to 2021. Different types of microplastics enumerated include PS, polystyrene; PE, polyethylene; PA, polyamide; PVC, polyvinylchloride; LDPE, low-density polyethylene; PET, polyethylene terephthalate; PHB, polyhydroxybutyrate; HDPE, high density polyethylene; PP, polypropyleneBack to article page
