Summary

Microplastic characterization in surface sediments of the Kayamkulam estuary in southwestern India found fibers and fragments dominated by polyethylene and polypropylene, establishing a pollution baseline for this ecologically important wetland.

Polymers
Study Type Environmental

The present study aims to formulate the characterization and distribution of microplastic in the estuarine surface sediments of Kayamkulam estuary, southwest coast of India. The sediments were dominated by fibre and film shaped microplastic substances. The surface sediments were dominated by <1000 μm microplastics. The composition of microplastics in descending order was as follows: polyester > polypropylene > polyethylene. The distribution of microplastics was significantly higher than that observed in the other study regions, except for Pearl river estuary and Guanabara Bay. The distribution of microplastics was chiefly controlled by estuarine inundating water and the distance of the sampling site from the open sea.
