Summary

This review summarizes how microplastics enter freshwater ecosystems from sources like industrial runoff, urban waste, and agriculture, and how they accumulate in sediments where aquatic organisms ingest them. Researchers found that microplastics reduce feeding efficiency, inhibit growth, and harm reproduction in freshwater species, while also acting as carriers for toxic chemicals that build up through the food chain. The study highlights the need for better waste management and further research to understand the full scope of risks to both aquatic life and human health.

Study Type Environmental

Microplastics (MPs) are widespread pollutants in freshwater ecosystems, originating from industrial runoff, urban waste, and agriculture. These particles, ranging from nanometers to millimeters, accumulate in sediments and pose risks to aquatic life. Freshwater organisms ingest MPs, leading to reduced feeding efficiency, growth inhibition, and reproductive toxicity. MPs also act as vectors for toxic chemicals, contributing to bioaccumulation and biomagnification, raising human health concerns. Potential impacts include inflammation, oxidative stress, and chemical exposure. This review explores MP sources, transport mechanisms, and ecotoxicological effects, highlighting the need for further research and effective waste management to mitigate their risks.
