Occurrence, characterization, and source delineation of microplastics in the coastal waters and shelf sediments of the central east coast of India, Bay of Bengal
This study characterized microplastics in surface water and shelf sediments along 1,200 km of India's east coast, finding average concentrations of 5.3 million particles per square kilometer in surface water and 209 particles per kilogram in sediments. Fibers dominated surface water while fragments dominated sediments, with riverine inputs and fishing activities identified as primary sources.
Spatiotemporal distribution of microplastics in the catchment of lake akkulam-veli, kerala, india
Researchers quantified and characterized microplastics in seasonal surface water samples from the Akkulam-Veli lake catchment in Kerala, India, finding highest concentrations during pre-monsoon (5100 particles/m3) and lowest during post-monsoon (1838 particles/m3), indicating seasonal and hydrological drivers of microplastic distribution.
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.
Morphometric characteristics and spatiotemporal heterogeneity of microplastics on the north-east coast of India
Survey of surface waters along the northeast coast of India found microplastics present in all sampled water masses, with higher concentrations during the monsoon season than the post-monsoon period, and fragments and fibers making up the vast majority of particles. The seasonal pattern suggests land-based runoff is a major delivery pathway, with implications for the many coastal communities in the region that depend on these waters for fishing and livelihoods.
Deciphering the seasonal dynamics of microplastic morphotypes and associated co-contaminants along the northwest coast of India
Researchers studied seasonal variations in microplastic abundance along the northwest coast of India bordering the Arabian Sea. The study found dramatically higher microplastic concentrations during monsoon season compared to pre- and post-monsoon periods, with polypropylene and high-density polyethylene as the dominant polymer types.
Seasonal microplastic variations in estuarine sediments from urban canal on the west coast of Thailand: A case study in Phuket province
Researchers investigated seasonal variations in microplastic contamination in estuarine sediments from an urban canal in Phuket, Thailand. They found microplastic abundance was higher in the dry season than the rainy season, with rayon and polyester being the most common polymer types, suggesting that seasonal hydrological patterns and human activities both influence microplastic distribution in urban estuaries.

Microplastic pollution and its implicated risks in the estuarine environment of Tamil Nadu, India
Researchers investigated microplastic pollution across 19 estuaries in Tamil Nadu, India, measuring contamination in water, sediment, and marine organisms. They found microplastic levels were higher during monsoon season due to stormwater discharge, and estimated that local residents may ingest approximately 781 microplastic items through fish and 2,809 through shellfish annually. The study suggests that estuarine microplastic pollution poses meaningful human exposure risks through seafood consumption.
Insights into the seasonal distribution of microplastics and their associated biofilms in the water column of two tropical estuaries
Researchers tracked microplastic levels and the bacterial communities growing on them in a tropical estuary in southwest India across wet and dry seasons. Microplastic concentrations were about seven times higher during the wet season due to increased runoff, and the biofilms on these plastics included potentially harmful bacteria. The study shows that seasonal weather patterns influence how much microplastic contamination reaches coastal waters where local communities fish and collect seafood.
