Microplastics are raining down on Patna
AI summary Read the abstract
Rainwater samples collected in Patna, India's heavily polluted Bihar capital contained nine distinct types of microplastics, demonstrating that atmospheric deposition is delivering plastic particles through precipitation in South Asian urban environments. Microplastics in rainwater represent a direct and unavoidable human exposure pathway, contaminating drinking water sources, crops, and open food supplies in densely populated cities.

Microplastic in the Terrestrial Ecosystem of India
AI summary Read the abstract
This review documented sources and distribution of microplastics across India's terrestrial ecosystems — including agricultural lands, urban soils, and road surfaces — and assessed their effects on soil health, plant uptake, and terrestrial organisms. Terrestrial microplastic contamination is a critical but undermonitored exposure pathway, as particles accumulate in cropland soils and can enter the human diet through fruits, vegetables, and grains.
Microplastic Pollution in India as an Emerging Concern
AI summary Read the abstract
Researchers reviewed the sources, distribution, and ecological impacts of microplastic pollution across India's diverse environmental compartments, highlighting gaps in monitoring data and the absence of national regulatory frameworks specific to MNP contamination. Closing these knowledge and governance gaps is essential for a country whose rivers, coastlines, and agricultural soils face mounting plastic pollution pressure affecting food and water security.
Microplastic Pollution in India: An Overview
AI summary Read the abstract
This overview characterized microplastic contamination across India's marine, freshwater, and terrestrial environments, documenting polymer types, concentration ranges, and geographic hotspots tied to urbanization, industry, and poor waste management infrastructure. India's scale as a plastic producer and its rapidly growing coastal and inland population make understanding domestic contamination patterns urgent for protecting both ecosystems and public health.
Microplastic in the Sediment Ecosystem of India
AI summary Read the abstract
This study investigated microplastic accumulation in sediment ecosystems across India, including deep-sea environments, finding widespread contamination across diverse marine habitats. Sediment microplastics are a critical concern because they act as long-term reservoirs that slowly release particles and associated toxins into benthic food webs, ultimately reaching commercially harvested seafood consumed by humans.
