ClearNanoplastics toxicity in aquatic organisms: a review of effects on selected marine and freshwater species
This review synthesizes findings from 128 studies on the effects of nanoplastics on five representative freshwater and marine species, from microalgae to fish. Researchers found that even at low concentrations, nanoplastic exposure can cause oxidative stress, membrane damage, developmental disorders, and reproductive impairment across species. The study highlights significant knowledge gaps around chronic, environmentally realistic exposure levels and calls for standardized testing methods.
Nanoplastics toxicity in aquatic organisms: a review of effects on selected marine and freshwater species
This review analyzed 128 studies on the effects of nanoplastics on five representative freshwater and marine species, including microalgae, bivalves, crustaceans, and fish. Researchers found that even low concentrations of nanoplastics can cause oxidative stress, membrane damage, developmental disorders, and immune and nervous system dysfunction. The study highlights that particle size, concentration, aging status, and the presence of co-contaminants all influence toxicity, and calls for more research at environmentally realistic exposure levels.
