Characteristics of microplastics in the beach sediments of Marina tourist beach, Chennai, India
Researchers conducted the first baseline study of microplastic pollution in beach sediments at Marina and Pattinapakkam beaches in Chennai, India. They identified an average of 459 and 297 microplastic particles at the two sites respectively, with polyethylene being the dominant polymer type. The study suggests that both human activities and natural coastal processes contribute to microplastic accumulation at these popular tourist beaches.
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.
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.
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.
Distribution 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.
Impact of flooding events on microplastic distribution from rivers to coastal areas: a case study from Tuticorin, Southeast India
Researchers compared microplastic abundance in river, estuarine, and coastal water and sediment before and after a 2023 flood event in Southeast India. Flood events tripled microplastic abundance in surface water (from 28 to 95 items/L) and increased sediment concentrations 1.5-fold, demonstrating that flooding is a major driver of microplastic redistribution.
Abundance, characteristics and surface degradation features of microplastics in beach sediments of five coastal areas in Tamil Nadu, India
Microplastic abundance and surface weathering features were characterized in beach sediments from five coastal areas in Tamil Nadu, India, with concentrations reaching up to 439 particles per kg and polyethylene and polypropylene dominating.
Micro-plastic pollution along the Bay of Bengal coastal stretch of Tamil Nadu, South India
Researchers quantified microplastic particles in water column, wet sediment, and dry sand samples from Marina Beach, Chennai, India — one of the world longest urban beaches — using optical microscopy. Fibrous microplastics were dominant across all matrices (52-79%), with concentrations indicating significant pollution along this heavily urbanised coastline.
Contamination and characterization of microplastics in different sediments of the river estuaries (the inner Gulf of Thailand)
Researchers measured microplastic contamination in river estuary sediments in the inner Gulf of Thailand, finding widespread contamination at all sites. The study characterizes the types and abundance of microplastics in a highly trafficked coastal region of Southeast Asia.
Abundance and distribution of subsurface microfibres and seabed macrolitter in Thoothukudi, Gulf of Mannar, South-east coast of India
This study measured the abundance and distribution of microfibers and larger plastic litter in coastal waters and seafloor sediments off Thoothukudi, India, finding widespread contamination. Microfibers were present throughout inshore waters, contributing to the growing body of evidence for plastic contamination along India's coastlines.
Sampling and Analysis of Microplastics in the Coastal Environments of Sri Lanka: Estuaries of Kelani River to Mahaoya

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.
Type and Distribution of Microplastic Contamination in Beach Sediment Along the Coast of the Lower Gulf of Thailand
Microplastic contamination was surveyed at five beaches along Thailand's lower Gulf Coast, with Talo Kapo showing the highest abundance and fragment-type particles being most common. The findings document baseline plastic pollution levels and polymer types across different coastal settings.
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.
Microplastic prevalence in the beaches of Puducherry, India and its correlation with fishing and tourism/recreational activities
A survey of six beaches on India's Puducherry coast found microplastic concentrations averaging 72 particles per 100g of sediment, with a strong positive correlation between fishing activity and microplastic abundance, but no significant relationship with recreational tourism. The findings suggest that fishing-related plastic waste is a more important local source of beach microplastic contamination than tourism activities.
Occurrence and distribution of microplastics at selected coastal sites along the southeastern United States
Researchers quantified microplastics in beach sand at 18 U.S. National Park beaches in the Southeast and built a model to predict how ocean currents transport plastic debris.

Anthropogenic particle abundance and characteristics in seawater and intertidal sediments of the Tonkin Bay Coast (North Vietnam)
Researchers measured microplastic contamination in seawater and intertidal sediments at four sites along the northern Vietnam coast, finding fiber particles as the dominant type in both compartments. Higher microplastic levels were recorded during the rainy season, suggesting rivers are a primary transport route carrying plastic from inland sources to the sea. The study provides rare baseline data for a developing-country coastal zone and emphasizes that even smaller polymer fragments below the measured size range likely represent a significant unquantified hazard.
