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.
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.
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.
Microplastic in the coral reef environments of the Gulf of Mannar, India - Characteristics, distributions, sources and ecological risks
Microplastic surveys in the coral reef environments of the Gulf of Mannar, India found that polyethylene and polypropylene were the dominant polymers, with land-based sources being the main contributor and pollution load indices indicating moderate to high ecological risk.
The extent of microplastic pollution along the eastern coast of India: Focussing on marine waters, beach sand, and fish
Researchers assessed microplastic contamination across water, sand, and fish from seven major beaches along India's eastern coast, finding widespread pollution dominated by polyethylene and polystyrene with hazard indices indicating potential ecological risk.
Potential Ecological Risk Assessment Studies Based on Source and Distribution of Microplastics from the Surface Sediments of Tropical Backwaters, Kerala, India
Researchers characterized microplastic pollution in surface sediments of three tropical estuaries along the southwest coast of Kerala, India, finding 407 total particles and conducting ecological risk assessment to evaluate hazard levels from microplastic accumulation.
Distribution and characterization of microplastic from reef associated surface sediments of Vembar group of Islands, Gulf of Mannar, India
Researchers collected reef sediment samples from three islands in the Vembar group in the Gulf of Mannar and found microplastic contamination dominated by polypropylene (most abundant), nylon (32.3%), polyethylene (19.6%), and polystyrene (5.7%), with irregular and fiber shapes predominating and Upputhanni Island showing the highest particle count at 154 particles.
Assessment of micro and macroplastics along the west coast of India: Abundance, distribution, polymer type and toxicity.
This study assessed the abundance and types of micro- and macroplastics on ten beaches along India's west coast, finding plastic in all locations with fragments being the most common form. Polymer analysis revealed polypropylene, polyethylene, and polystyrene as the dominant types, and toxicity testing indicated the plastic-contaminated sediments posed ecological risks.
Microplastic pollution in surface sediments of Coromandel coastline, South-East Coast, India: Diversity index, carbonyl index, pollution load index, risk fraction and MPs inventory
Researchers surveyed microplastic pollution across a 1,076-kilometer stretch of India's Coromandel coastline, using multiple indices to assess abundance, degradation, and ecological risk. They found that microplastic levels varied significantly between wet and dry seasons, with dry season samples showing higher concentrations. The study provides a comprehensive baseline assessment of microplastic contamination along one of India's most extensive coastal regions.
