Nanoplastic exposure impairs host fitness and parasite transmission with transgenerational maternal reproductive costs in the Daphnia-fungal parasite system

Summary

Scientists found that tiny plastic particles (nanoplastics) harmed water fleas (a small aquatic creature used to study environmental health), making them less healthy overall and affecting how diseases spread among them—and these harmful effects even carried over to their offspring's ability to reproduce. While this study was done in water fleas, not humans, it adds to growing evidence that nanoplastics—now found in our water, food, and even our bodies—can disrupt biological systems across generations, which is a good reason to keep researching their effects on human health too.
