Microplastic exposure studies should be environmentally realistic

Summary

Researchers argue that many laboratory studies on microplastic effects use concentrations far higher than what is actually found in the environment, which can lead to misleading conclusions about real-world risks. They call for experiments that better reflect environmental conditions, including realistic particle sizes, shapes, and concentrations. The study emphasizes that more environmentally relevant research is needed to accurately assess the true ecological threat of microplastic pollution.
