Summary

Researchers studied how UV-B radiation affects the toxicity of nanoscale polystyrene particles to water fleas (Daphnia magna). They found that UV-B exposure reduced the overall toxicity of the nanoparticles but caused them to release small toxic molecules into the surrounding water. The findings suggest that sunlight-driven degradation of nanoplastics may alter their environmental risks in unexpected ways.

Models

UV-B irradiation on 53 nm amine modified polystyrene nanoparticles lowers the toxicity to Daphnia magna and releases small toxic molecules.
