Researchers surveyed microplastic pollution in the Chapora River in Goa, India, finding concentrations ranging from 0.1 to 0.47 particles per liter across sampling stations. Fibers were the dominant shape, accounting for over 77% of particles, with polyethylene and polypropylene as the most common polymers. The study suggests that both urban activities and fishing contribute to microplastic contamination in this tropical river system.

Researchers characterized microplastics in surface waters of India's Chalakudy River, finding an average of 55.81 particles per liter dominated by fragments and low-density polyethylene, with smaller particles posing particular risks of accidental ingestion by aquatic organisms.
Textural characteristics and abundance of microplastics in the Nethravati river estuary sediments, south-west Mangalore beach, India
This study characterized microplastics in sediments from the Nethravati River estuary and adjacent beach in southwest India, finding that fibers made up 96% of all particles and polyamide (nylon) was the dominant polymer type at 60%. Secondary microplastics — fragments from the breakdown of larger plastic items — were far more common than primary microplastics. The study highlights how rivers funnel microplastic pollution into coastal zones where it accumulates and threatens marine biodiversity.
