Polystyrene Microplastics Found to Cause Fish Toxicity at Environmentally Relevant Concentrations

According to the abstract of a September 8, 2023 ACS Environmental Science & Technology article https://pubs.acs.org/doi/10.1021/acs.est.3c02769 by researchers with Guangzhou University in China who “… investigated the mechanism underlying the perturbation of hepatic lipid metabolism in response to micro/nanoplastic (MP/NP) exposure at environmentally relevant concentrations ... Polystyrene (PS) MPs/NPs with different sizes (0.1, 0.5, and 5.0 μm) … showed that PS MPs/NPs were readily internalized and accumulated in various internal organs/tissues, especially in fish liver and muscle. Smaller-sized NPs caused more severe toxicity than larger MPs, including hepatic steatosis, inflammatory response, and disturbed liver function ... These findings highlight the potential adverse effects of environmental MPs/NPs on aquatic organisms, raising concerns about their ecotoxicity and food safety …” #PlasticWaste #SingleUsePlastic #MicroPlastics #NanoPlastics #FishToxicity
