Characteristics, Contamination Levels, and Ecosystem Risk Assessment of Microplastics in Surface Water of a Highly Urbanized River from a Developing Country

Researchers characterized microplastic contamination in an urban river near a megacity in a developing country, finding concentrations of 350 to 660 particles per cubic meter of water. Polyethylene and polypropylene from household and municipal waste were the most common types, and a risk assessment found concerning contamination levels at several sampling sites. The study highlights how rivers in developing nations can serve as major pathways for microplastics to reach the ocean and enter the food chain.

Microplastics in freshwater ecosystems: what we know and what we need to know

This review examines the state of knowledge on microplastic contamination in freshwater ecosystems, which have received far less scientific attention than marine environments despite being major pathways for plastic transport. Researchers found that freshwater microplastic concentrations can be extremely high near urban areas and that organisms from insects to fish readily ingest these particles. The study identifies key research gaps including the need for standardized detection methods and better understanding of how microplastics move through and affect freshwater food webs.
