Nanoplastics – Effects on Human Liver and Lung Cells Studied

The abstract of an August 25, 2022 ACS Environmental Science and Technology article by researchers in China with the Hong Kong Baptist University, Chinese Research Academy of Environmental Sciences, The Education University of Hong Kong and Southern University of Science and Technology reports that “… nanoplastic (NPs) toxicity in humans is far from being understood ... In this study, we investigated the effects of 80 nm NPs on mitochondrial functions and metabolic pathways in normal human hepatic (L02) cells and lung (BEAS-2B) cells. NP exposure did not induce mass cell death; however, transmission electron microscopy analysis showed that the NPs could enter the cells and cause mitochondrial damage … These alterations were observed at NP concentrations as low as 0.0125 mg/mL, which might be comparable to the environmental levels ... This study identifies NP-induced mitochondrial dysfunction and metabolic toxicity pathways in target human cells, providing insight into the possibility of adverse outcomes in human health …” #PlasticWaste #SingleUsePlastic #MicroPlastics #NanoPlastic @hkbaptistu
