Microplastic pollution in aquatic ecosystems

Overview

Research has highlighted the pervasive impact of microplastic pollution on aquatic life and environments. In the United States, a study published in Environmental Chemistry and Ecotoxicology found that biodegradable polylactic acid (PLA) microplastics affect the blood cells of rainbow trout. Researchers observed changes in the activity of immune defense cells and potential interference in cell communication, noting that risks may increase when particles are aged under simulated sunlight.

In Bangladesh, studies published in ‘Environmental Pollution’ identified microplastic contamination in commercial freshwater fish farming ponds. Researchers found microplastics in the sediment of all tested ponds and in the digestive tracts of various fish species, including Rui, Katla, Pangas, Mrigal, Common Carp, and Sarputi. The findings indicate a transfer of particles from sediment to fish, raising concerns for both aquatic ecosystems and public health.
