Summary

This paper discusses the environmental and health concerns raised by micro- and nanoplastics, with a focus on nanoplastics that can breach biological barriers due to their very small size. The authors note that insufficient analytical tools make it difficult to understand the full extent of nanoplastic hazards.

Micro-nano plastics originating from the prevalent usage of plastics have raised increasingly alarming concerns worldwide. However, there remains a fundamental knowledge gap in nanoplastics because of the lack of effective analytical ...Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm in length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, nanoplastics are believed to be more toxic since their ...
