ClearDistribution and characterization of microplastics in beach sand from three different Indian coastal environments
Beach sands from three locations on the Indian coast were analyzed for microplastics, finding concentrations of 45–220 particles/kg dry sand with polyethylene (43%) as the dominant polymer, followed by PET and polystyrene. The study establishes baseline contamination data for Indian beaches and demonstrates consistent polymer profiles across geographically distinct coastal environments.

Researchers quantified microplastic contamination across 25 beaches along the Maharashtra coast of India, finding widespread pollution with significant variation between sites. They identified microplastic concentrations correlated with anthropogenic activities near each sampling location. The study provides baseline data on coastal microplastic pollution in this densely populated region and highlights the connection between human activity and beach contamination levels.
Microplastic profile and ecological risk assessment of emerging estuarine contaminants in two tourist hotspots of northern Kerala backwaters
Researchers investigated microplastic pollution in sediments and water of two tourist-heavy estuarine systems in northern Kerala, India. They found average concentrations of 187 to 259 particles per kilogram in sediments and 251 to 284 particles per liter in water, with polyamide as the dominant polymer type, indicating high ecological risk driven by tourism, fishing, and poor waste management.
The distribution, characteristics, and potential impacts of microplastics in sediments from two tourist beaches along the northern Bay of Bengal
This study characterized microplastic contamination in sediments from two popular tourist beaches along the northern Bay of Bengal in Bangladesh, finding between 56 and 137 microplastic items per kilogram at both sites. Fibers and foam dominated, polyethylene was the most common polymer, and most particles were under 0.5 mm. The results point to tourism, industrial discharge, fishing, and river runoff as the main local sources, and provide the first baseline contamination data for this coastal region.
Distribution and characterization of microplastics in beach sediments from Karnataka (India) coastal environments
Researchers surveyed five beaches along the Arabian Sea coast in Karnataka, India, and found microplastic concentrations ranging from 264 to 1,002 particles per kilogram of dry sand. The majority of particles were small fragments less than 1 millimeter in size, and microscopy revealed signs of extensive environmental weathering. The study provides important baseline data on microplastic contamination along India's western coastline.
Microplastic distribution patterns in Kappil Beach sediments, Kerala
Beach sediment samples from Kappil, Kerala in India revealed 766 microplastic particles dominated by nylon fibers (78%), along with polyethylene and polystyrene, with the majority smaller than 1 mm. Risk assessments classified contamination as moderate to high, suggesting active fragmentation of larger plastic debris is ongoing. This baseline data is valuable for tracking pollution trends in Indian coastal ecosystems where fishing and tourism create significant plastic inputs.
Microplastics' occurrence, distribution, and chemical toxicity in backwater sediments from Puducherry Coast, Southeast India
Researchers measured microplastic concentrations in sediment cores from three sites along India's Puducherry coast, finding over 100 microplastic particles per square centimeter near the surface — with fibers and fragments made of PE, PP, and PET being most common — and high pollution risk scores at all sites.
Quantitative assessment of microplastic in sandy beaches of Gujarat state, India
Researchers quantified microplastic contamination across 20 sandy beaches on the Gujarat coast of India, finding average abundances ranging from 1.4 to 26 MPs per kilogram of sediment, with higher concentrations at beaches under greater anthropogenic pressure. Thread/fiber morphologies were the most abundant type, and the spatial distribution reflected local population density and tourist activity.
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.
