Study Reveals High Microplastic Contamination in Goa’s Estuarine Fisheries and Potential Human Risks
A study by CSIR-NIO and the Academy of Scientific and Innovative Research found significant microplastic contamination in fish along the Goa coast. Researchers identified 4,871 particles of 19 different types of polymers in 251 fish samples. Microplastics, primarily from fishing gear, tires, and wastewater, accumulate in the food chain through bioaccumulation. The study warns that human consumption of contaminated fish may lead to immune dysfunction, increased cancer risk, and neurotoxicity. The findings underscore the urgent need for better waste disposal and research into biodegradable alternatives to protect marine ecosystems and public health in coastal regions.
Key Points
- Microplastics enter the food chain and accumulate in higher organisms, a process known as bioaccumulation.
- The study found higher contamination on the sea floor and in benthic organisms compared to the water column.
- Common polymers found include those from fishing gear, textiles, and road residue.
- Human health risks include oxidative stress, reproductive impairment, and reduced growth.
Exam Facts
- Research institute: CSIR-National Institute of Oceanography (NIO)
