Microplastics Found in Pune's Freshwater Fish

Microplastics have been detected in freshwater fish commonly consumed in Pune, raising concerns about their entry into the human food chain. Researchers at MIT-WPU are investigating the presence, characteristics, and sources of these microplastics in popular fish like Rohu and Tilapia.

The study mapped Pune's fish supply chain, surveying wholesalers and distributors. It revealed that approximately 37-40 tonnes of freshwater fish, including Rohu and Tilapia, enter the city's market daily. This supply originates from aquaculture and is transported from various states, indicating an extensive interstate fish trade.

Laboratory analysis confirmed microplastic presence in fish samples, with particles including fibres, fragments, and pellets. The research estimates that regular consumption of freshwater fish over 50 years could lead to the ingestion of 93,600 to 124,800 microplastic particles. Further quantitative analysis is ongoing to understand the full health implications.

This research aims to provide crucial data on freshwater microplastic pollution in Pune. The findings are expected to inform policies on waste management, ecosystem conservation, and food safety, contributing to solutions for plastic pollution in freshwater environments.
