ClearOrganic Pollutants Associated with Plastic Debris in Marine Environment: A Systematic Review of Analytical Methods, Occurrence, and Characteristics
This systematic review summarizes research on organic pollutants that attach to plastic debris in marine environments. The findings are concerning for human health because microplastics in the ocean can absorb and carry toxic chemicals like pesticides and flame retardants, and when marine life ingests these contaminated particles, the pollutants can move up the food chain to our seafood.
Plastic pollution in the marine environment
This review provides a comprehensive overview of plastic pollution in coastal and marine environments, covering everything from how plastics enter the ocean to their effects on marine life. Researchers compiled global data showing microplastic concentrations ranging widely across different water bodies and sediments, with marine organisms accumulating significant amounts. The study underscores that plastic pollution causes ecological damage through entanglement, ingestion toxicity, and the transport of invasive species.

Removed Due to Policy Violations
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.
Enrichment of Persistent Organic Pollutants in Microplastics from Coastal Waters
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.
