The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants

Microplastics act as mobile carriers for persistent organic chemicals, altering their distribution and toxicity in ecosystems and the organisms, including humans, that consume them.
Interactions between polyaromatic hydrocarbons and microplastics: Environmental mechanisms and ecotoxicological impacts
This review examines how microplastics interact with polycyclic aromatic hydrocarbons, a class of toxic organic pollutants found throughout the environment.
