Microplastic pollution in agricultural fields adjoining nag and Pivali rivers of Nagpur district.
AI summary Read the abstract
This study examined microplastic pollution in agricultural soils adjacent to the Nag and Pivali rivers in Nagpur, India, finding that plastic waste degrading under UV exposure has introduced microplastics and nanoplastics into nearby farmland through river runoff.
Pollution due to microplastics in agricultural ecosystem is increasing due to dumping of plastic materials in the environment, which gets degraded due to long term exposure of UV radiation into microplastics and nanoplastics. These microplastics enter into adjoining rivers or water bodies through runoff and sewage water, or by any other means. During present investigation, agricultural fields on the banks of Nag and Pivali river of the Nagpur city were studied for microplastic contamination. This pollutant was found deep into the soil, thereby disturbing soil profile and reducing fertility.

Analysis of macro-and microplastics in the water, soil/sediment in riverine, riverbanks and irrigated farms in Arusha Tanzania
AI summary Read the abstract
Researchers analyzed both macro- and microplastics in water, sediment, and soil from rivers, riverbanks, and irrigated farmland in Arusha, Tanzania. They found that macroplastics were prevalent in riverine environments and degraded into microplastics, which then spread into agricultural soils through irrigation.
Assessment of microplastic pollution in agricultural soil of Bhopal, Central India

FTIR analysis of agricultural soil in Bhopal, India detected 307.5 and 69.5 microplastic particles per sample across two farming areas, with polyethylene and polypropylene dominating, primarily sourced from agrochemical packaging and atmospheric deposition. The findings confirm widespread microplastic contamination in Indian agricultural soils, raising concerns about uptake by food crops and subsequent human dietary exposure.
