This paper discusses how microplastics released into the sea environment accumulate organic pollutants and increase their concentration relative to the surrounding water, amplifying exposure risks for marine life. The review highlights microplastics as vectors that concentrate and transport toxic chemicals through marine food webs.
Today, the production of plastic materials has multiplied with the growth of the population and the development of industry in the world. Microplastics are released into the sea environment as a result of the decomposition of plastic materials and are carried into the water by wind or waves. Unlike small inorganic particles in seawater, microplastics increase the concentration of organic pollutants by splitting. Microplastics are ingested by marine life and have adverse effects on them. The potential degradation of these substances in the marine ecosystem is still being quantitatively evaluated and modelled. Due to the increasing levels of pollution by plastics in the seas, a better understanding of the effects of microplastics in the ocean food web is of great importance.

Enrichment of Persistent Organic Pollutants in Microplastics from Coastal Waters
AI summary Read the abstract
Researchers quantified how microplastics concentrate persistent organic pollutants compared to suspended particulate matter in coastal seawater. They found that the concentrating effect of microplastics on these pollutants was one to two orders of magnitude greater than that of natural suspended particles. The study provides precise measurements of enrichment factors, suggesting that microplastics may serve as significant carriers of toxic organic chemicals in marine environments.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
AI summary Read the abstract
This review summarizes how microplastics in the environment interact with organic pollutants—adsorbing, carrying, and releasing them. Microplastics act as mobile carriers for persistent organic chemicals, altering their distribution and toxicity in ecosystems and the organisms, including humans, that consume them.
The Dual Role of Microplastics in Marine Environment: Sink and Vectors of Pollutants
AI summary Read the abstract
This review examines the dual role of microplastics in the marine environment as both accumulators of persistent organic pollutants and vectors that transport these chemicals and other contaminants including heavy metals, pharmaceuticals, and pathogens. The study highlights how microplastics can concentrate toxic substances from seawater and then release them when ingested by marine organisms, creating additional exposure pathways.
Role of Microplastics in the Biomagnification of PBTs in Marine Organisms
AI summary Read the abstract
This paper reviews how microplastics may facilitate the biomagnification of persistent, bioaccumulative, and toxic (PBT) chemicals in marine food webs, given that plastic particles can adsorb and concentrate pollutants. The work highlights microplastics as a potential new vector for introducing toxic chemicals into marine organisms and up through the food chain.
