Ecotoxicity of Microplastics

Summary

Tiny plastic particles called microplastics—smaller than 5mm, often invisible to the naked eye—are turning up everywhere in our environment, from oceans to soil, and this review paper pulls together what scientists currently know about the harm they can cause to living things. While much of the research so far has focused on wildlife and ecosystems, these findings matter for us too, since the same plastics contaminating fish, water, and food chains can end up on our plates. The takeaway: microplastic pollution is a growing concern worth watching, even though scientists are still working out exactly how much risk it poses to human health.
