Seasonal and spatial variations in the distribution pattern, sources and impacts of microplastics along different coastal zones of Tamil Nadu, India
Surveys of four coastal zones in Tamil Nadu, India found microplastics in both sediments and water at all sites, with the highest concentrations during the monsoon season when river runoff carries more plastic waste into the ocean. The researchers identified 16–23 different polymer types per season and found that weathered particles were carrying hazardous heavy metals on their surfaces. The study provides one of the most detailed spatiotemporal profiles of coastal microplastic contamination in India, underscoring the need for urgent pollution control measures in heavily populated coastal regions.

A survey of microplastic contamination at 25 sites along the Tamil Nadu (Chennai) coastline of India found widespread contamination from multiple sources. The findings document the scale of microplastic pollution in a major coastal region and highlight the need for local management interventions.
Microplastics pollution in tropical estuary (Muttukadu Backwater), Southeast Coast of India: Occurrence, distribution characteristics, potential sources and ecological risk assessment
Scientists surveyed microplastic contamination in the water and sediments of a tropical estuary on India's southeast coast. They found moderate to high levels of microplastic pollution, with common polymers like polyethylene and polystyrene contributing the most to ecological risk. The presence of trace metals on microplastic surfaces suggests these particles may also serve as carriers for heavy metal contamination in coastal ecosystems.
