Microplastic pollution unveiled: the consequences of small unregulated dumping in villages, spanning from soil to water
Researchers studied microplastic pollution at unregulated village dumpsites in India and found widespread contamination in the surrounding soil and water. The study identified a variety of plastic types and shapes, including fibers, fragments, and films, moving from dump sites into nearby aquatic environments. This matters because informal waste disposal in rural areas is a largely overlooked source of microplastic pollution that can affect local water quality.
Exploring the abundance of microplastics in Indian landfill leachate: An analytical study
Researchers analyzed microplastics in leachate from two major landfills in India and found concentrations of 1,473 to 2,067 particles per liter, with most particles smaller than 100 micrometers. Polyethylene terephthalate, polypropylene, cellulose acetate, and PVC were the most common plastic types identified. Since landfill leachate can seep into groundwater and nearby water bodies, these findings raise concerns about microplastic contamination of drinking water sources near dump sites.
Spatial distribution and ecological risks of microplastics in agricultural soils near a solid waste dumpsite in southwest Bangladesh
Researchers assessed microplastic contamination in agricultural soils surrounding a municipal solid waste dumpsite in southwest Bangladesh, characterizing the types, spatial distribution, and ecological risks. They found significant microplastic accumulation in soils near the dump, with contamination levels decreasing at greater distances. The study highlights that waste dumpsites are important point sources of microplastic pollution that can affect the fertility and ecological health of surrounding agricultural lands.
Spatial distribution of microplastic concentration around landfill sites and its potential risk on groundwater
Researchers found microplastic contamination in groundwater near two municipal waste dump sites in South India, with levels ranging from 2 to 80 particles per liter.

The study shows that even remote freshwater sources used for drinking and irrigation are contaminated with microplastics, raising concerns for the communities that depend on them.
Subsurface transport and environmental risks of microplastic pollution: influence of land use and seasonal variability
Researchers systematically investigated how microplastics move vertically through soil across five different land use types during pre-monsoon and post-monsoon seasons. Dumpsites had the highest microplastic concentrations at nearly 40,000 particles per kilogram, while woodlands had the lowest at around 500 particles per kilogram. The study found that smaller microplastics traveled deeper into soil, especially after monsoon rains, and that land use type significantly influenced both the amount and composition of microplastic contamination.
Spatiotemporal distribution and ecological hazards of microplastic pollution in soil water resources around a wastewater treatment plant and municipal solid waste site
Researchers mapped the spatial and seasonal distribution of microplastics in soil, water, and sediment near a wastewater treatment plant and municipal landfill in northern India. They found elevated microplastic concentrations in leachate and areas immediately surrounding both facilities, with seasonal variations in contamination levels. The study highlights that both wastewater treatment plants and solid waste sites serve as significant local sources of microplastic pollution to surrounding environments.
Microplastic pollution in landfill soil: Emerging threats the environmental and public health
Researchers measured microplastic contamination in soil at a landfill near residential areas in Indonesia and found extremely high levels of over 60,000 particles per kilogram. The most common types were fragments of polyethylene, PVC, polystyrene, and polypropylene. The study raises public health concerns because landfills near populated areas can release microplastics into surrounding soil and water, creating exposure pathways for nearby communities.
Extraction and characterization of microplastics in biomined good earth fractions: assessment of urban and suburban landfill sites, India
Researchers extracted and characterized microplastics from biomined landfill materials at five sites in West Bengal, India, finding concentrations ranging from 11,500 to 34,500 particles per kilogram. The most common types were fragments, films, and fibers, with HDPE and LDPE as the primary polymers, though some sites had elevated hazard levels due to the presence of PVC. The study highlights the need for standardized methods to assess microplastic contamination in landfill-derived materials before they are reused in development projects.
Implications of solid waste dumps on the microplastic abundance in groundwater in Kollam, India
Groundwater wells near waste dump sites in Kollam, India contained an average of 12 microplastic particles per liter, with fibers being the most common type. Larger dump sites were associated with higher microplastic levels, and the groundwater near heavy dumping sites was also more acidic, suggesting leachate from waste dumps is contaminating the water supply. This is a direct human health concern because many communities depend on well water for drinking, and microplastics in groundwater are difficult to remove.
Multifaceted analysis of microplastic pollution dynamics in the Yamuna river: Assessing anthropogenic impacts and ecological consequences
Researchers surveyed microplastic pollution across 29 locations along the Yamuna River in India, spanning urban, rural, and industrial zones. They found an average of nearly 15,000 microplastic particles per liter, with hazardous polymers like PET and nylon being most common and concentrations highest near urban and industrial areas. The study highlights that the Yamuna is heavily contaminated with microplastics and that population density and industrial activity are major drivers of this pollution.
