Summary

This meta-analysis examines how micro- and nanoplastic particles affect the growth of microalgae, which form the base of aquatic food chains. The results show mixed outcomes, with some studies finding growth inhibition and others finding stimulation. Understanding how microplastics affect algae is important because disruptions at the base of the food chain can cascade up to the fish and seafood we eat.

Study Type Review

Background: Ecological impacts of micro-and nanoplastics particles (MNP) are among the most discussed environmental concerns. In algae, MNP are commonly hypothesized to reduce growth, which is a standard ecotoxicological endpoint. However, the reported test outcomes vary, with both growth inhibition and stimulation being observed. Due to this conflict of information, a data synthesis for MNP potential to cause growth inhibition in toxicity testing is needed.
