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.
Urbanization increases microplastic pollution in beach sediments along the Chennai Coast, South India
Surveys of beaches in China found that microplastic concentrations rise with proximity to urban areas, with higher urbanization correlating with more fragments and pellets in sediments. The findings underscore how human population density directly drives coastal microplastic pollution levels.
Prevalence of microplastics in the sediments of Odisha beaches, southeastern coast of India
This first study of microplastic prevalence on beaches of the Odisha coast in southeastern India documented widespread contamination, with fiber and fragment types dominated by polypropylene and polyethylene across multiple beach sites.
Macro-, meso- and microplastic debris in the beaches of Tuticorin district, Southeast coast of India
Researchers surveyed eight sandy beaches along the Tuticorin district coast in southeast India for macro-, meso-, and microplastic debris. The study found microplastic concentrations ranging from 25 to 83 items per square meter, with contamination levels varying by site depending on the intensity of fishing and other human activities, confirming widespread plastic pollution along India's southeastern coastline.
Estimation of microplastics in sediments at the southernmost coast of India (Kanyakumari)
This study estimated microplastic abundance in beach sediments at Kanyakumari, the southernmost tip of India, finding higher concentrations at harbors and tourist areas compared to residential fishing communities. The results indicate that both recreational activity and harbor operations are significant sources of microplastic accumulation on Indian beaches.
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.
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.

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.
Assessment of Microplastic Pollution Across the Malabar Coast, India
Researchers assessed microplastic contamination in water, sediment, and commercially important fish along the Malabar coast in India. They found microplastics in all sample types, with the highest concentrations in fish gastrointestinal and gill tissues, predominantly consisting of fragments and fibers of common plastics like HDPE, PET, and nylon. The study points to direct discharges, runoff, and poor wastewater management as key sources, underscoring the need for regulatory measures to protect both marine ecosystems and the people who consume seafood from the region.
