Researchers examined the distribution, composition, and abundance of microplastics in the Hiren-2 Reservoir in Gujarat, India, finding microplastic concentrations ranging from 1.756 to 5.422 particles per liter. The study characterized microplastic contamination in a freshwater reservoir representing a growing concern for drinking water quality and aquatic ecosystem health in South Asia.
Microplastics in freshwater lakes: A case study from Southern India
Researchers assessed microplastic contamination in Vellayani Lake, a major drinking water source in southern India, and found particles present across all sampling sites and seasons. Fibers were the most common shape, with polyethylene and polypropylene as the dominant polymer types, likely originating from domestic wastewater and fishing activities. The study highlights the need for monitoring microplastic pollution in freshwater lakes that serve as critical drinking water supplies.
Microplastic contamination and ecological risk in a riverine system: A case study from the Valvanti River, Goa, India
Researchers conducted a comprehensive assessment of microplastic contamination in the Valvanti River in Goa, India, finding concentrations ranging from 1.1 to 7.5 particles per liter. Despite moderate concentrations, ecological risk assessments indicated significant hazard levels due to the types of polymers present, with polypropylene, polyamide, and PET as the dominant plastic types.
Comprehensive study of the microplastic footprint in the urban pond and river of Eastern India
Scientists measured microplastic contamination in an urban river and pond in Eastern India and found concerning levels of 59-100 particles per liter in water and 167-193 particles per gram in sediment, with risk assessments showing crisis-level pollution. The dominant plastics found -- nylon and polyethylene -- come from everyday products, and the high contamination levels in these freshwater sources pose risks to the communities that depend on them.
