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.

Ecological risk assessment classified the estuary as facing medium to high risk, highlighting the urgent need for waste reduction policies and regular monitoring of coastal waterways in India.
The estuarine plastics menace: Insights into prevalence, characterization and polymeric risk assessment of microplastics in the Mahi River Estuary, Gujarat, India
Researchers assessed microplastic contamination along 30 sites of the Mahi River Estuary in Gujarat, India, characterizing particle abundance, morphology, polymer type, and ecological risk. Microplastics were found at all sites with concentrations and polymer risk indices reflecting the estuary's proximity to urban and industrial sources.
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.

Researchers conducted the first study of microplastics in Vembanad Lake, Kerala, India, finding plastic particles across sampled sites and documenting the types and polymer composition of contamination in this important freshwater ecosystem.
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.
Ecological assessment of microplastic contamination in surface water and commercially important edible fishes off Kadalundi estuary, Southwest coast of India
Researchers documented microplastic contamination in both the surface water and 12 commercially important fish species from the Kadalundi estuary in India. Fibers were the most common type of microplastic found, with contamination levels varying across fish species. The findings are significant because this estuary is Kerala's first community reserve, and the contaminated fish are widely consumed by local populations.
Distribution and characterization of microplastics and ecological risks in Vellayani Lake, Kerala, India
Researchers surveyed Vellayani Lake in Kerala, India, for microplastic contamination and found particles in both water and sediment samples across the lake. The most common types were fibers and fragments, primarily from polyethylene and polypropylene, likely originating from household waste, fishing activities, and agricultural runoff. The ecological risk assessment indicated moderate contamination levels, raising concerns for this freshwater lake that serves local communities.

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.

Ecological footprint of microplastics in coastal and estuarine environments of India: Sediment-water interface analysis
This study mapped microplastic pollution across 16 coastal and estuarine sites along India's coastline, finding contamination everywhere with concentrations varying based on local human activities like port operations, tourism, and fishing. The microplastics were mostly small fibers and fragments under 500 micrometers, and certain plastic types were especially good at absorbing heavy metals. This means microplastics in coastal waters serve as carriers that can transport toxic metals into the seafood chain and ultimately into human diets.
