Status of Microplastic Accumulation in Water and Sediments of Selected Estuarine Ecosystem of Southern Kerala, India
Researchers measured microplastic levels in water and sediment from estuaries in southern Kerala, India, finding significant contamination in both habitats. The study identifies these coastal estuaries as accumulation zones for microplastic pollution, posing risks to local aquatic life and fishing communities.
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 pollution in tropical estuary (Muttukadu Backwater), Southeast Coast of India: Occurrence, distribution characteristics, potential sources and ecological risk assessment
Scientists surveyed microplastic contamination in the water and sediments of a tropical estuary on India's southeast coast. They found moderate to high levels of microplastic pollution, with common polymers like polyethylene and polystyrene contributing the most to ecological risk. The presence of trace metals on microplastic surfaces suggests these particles may also serve as carriers for heavy metal contamination in coastal ecosystems.
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.
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.
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.
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.
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.
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.
Seasonal variation of microplastics in tropical mangrove waters of South-western India
Researchers measured seasonal variations in microplastic contamination within tropical mangrove waters in South-Western India. They found that post-monsoon concentrations were highest at 1.42 microplastics per liter, while monsoon season had the lowest levels at 0.19 per liter. Fibers were the most common particle type, with polymers including polypropylene, PET, and polyethylene identified, likely originating from local tourism, aquaculture, and marine industries.
