ClearEmerging Global Threat of Microplastics and Their Impact on Soil Sustainability: A Case of Southeast Nigeria
This review examined microplastic pollution in Southeast Nigeria, focusing on sources from fragmented plastic waste and environmental and health impacts. The authors highlighted local knowledge gaps and called for regional policies addressing the ecological and endocrine-disrupting effects of microplastics in a rapidly developing area.
Microplastic Contamination and Its Impact on Soil Properties Across Different Land Uses in Cross River State, Nigeria
A survey of soils across four land-use types in southeastern Nigeria found microplastic concentrations up to 12 times higher in commercial areas than in forests, with contamination linked to changes in soil structure, nutrient availability, and water infiltration. This is the first large-scale assessment of microplastic distribution in Nigerian tropical soils, filling a major data gap for sub-Saharan Africa. The findings suggest that heavily contaminated commercial soils may have degraded agricultural and ecological functionality, with consequences for food security in the region.
The importance of microplastics pollution studies in water and soil of Nigeria ecosystems
This review highlights the lack of microplastic pollution research in Nigeria, despite the country's growing plastic production and consumption. The author calls for more local studies to generate data needed for science-based policy on plastic waste management in African ecosystems.
Plastic Pollution in the Environment in Nigeria: A Rapid Systematic Review of the Sources, Distribution, Research Gaps and Policy Needs
This systematic review examines plastic pollution across Nigeria's environment, including water, soil, air, and food. The research finds that plastic contamination is widespread but under-studied in African countries, with significant gaps in data and policy. Understanding plastic pollution in developing nations is critical because these regions often lack the waste management infrastructure to prevent microplastic contamination of food and water.
Sources, pollution, and ecological impacts of soil microplastics-A review
A comprehensive review summarized the sources, distribution, and ecological impacts of microplastics in soil environments, synthesizing evidence on how plastics affect soil organisms, structure, and agricultural productivity. The review calls for urgent policy action to address soil microplastic contamination as a threat to food security.
Tiny toxins, big problems: the hidden threat of microplastic in agroecosystems
This review examines the impacts of microplastic contamination in agricultural soils, covering sources from plastic mulch and irrigation, effects on soil structure, water retention, microbial diversity, and nutrient cycling, and consequences for crop health and food safety.
Investigation of microplastic contamination in waste dump soil from Minna Metropolis in Niger State and screening of indigenous microorganisms for biodegradation as potential mitigation strategy
Researchers investigated microplastic contamination in waste dump soils across Minna, Nigeria, and screened indigenous soil microorganisms for plastic biodegradation potential. They found microplastics in all sampled dump sites and identified several bacterial isolates capable of degrading common plastic polymers.
Assessment of Soil Microplastics and Their Relation to Soil and Terrain Attributes Under Different Land Uses
Researchers assessed microplastic contamination in tropical soils under different land uses including forest, grassland, and agricultural areas. They found that agricultural soils had the highest microplastic concentrations, likely due to the use of plastic-based materials in farming. The study reveals how land use practices and soil characteristics influence the distribution and accumulation of microplastics in tropical environments.
Microplastic Contamination in Agricultural Soils Across India: A Systematic Review of Studies and Research Gaps
This systematic review examines microplastic contamination in agricultural soils across India, an area that has received far less attention than waterways. The research identifies polluted irrigation water, industrial discharge, and plastic mulch as key contamination sources, raising concerns about microplastics entering the food supply through crops grown in contaminated soil.
Characterization of Microplastics and Associated Heavy Metals in Urban Soils Affected by Anthropogenic Littering: Distribution, Spatial Variation, and Influence of Soil Properties
Researchers sampled soils across residential, commercial, and industrial land-use types in urban areas and found microplastics in every location, with polypropylene, polyethylene, and polyamide as the dominant polymer types, at concentrations up to 850,000 particles per kilogram. Heavy metals were also associated with the plastic particles, meaning microplastics in urban soil may serve as combined carriers of chemical toxicants. The findings highlight urban soil as a major but underappreciated reservoir of microplastic pollution.
Environmental fate and impacts of microplastics in soil ecosystems: Progress and perspective
This review summarized knowledge on microplastics in soil environments, covering occurrence across agricultural, industrial, and urban soils, transport pathways, and ecological risks to soil organisms and plant communities. The authors identify key data gaps and methodological challenges that currently limit understanding of microplastic fate and impact in terrestrial systems.
The extent and impacts of soil pollution by microplastics
This study examines the extent and impacts of soil pollution by microplastics, reviewing evidence of how microplastic particles accumulate in terrestrial environments and affect soil ecosystems, organisms, and agricultural systems.
Micro Plastic Pollution in Soil Environment: A Comprehensive Review
This comprehensive review covers sources, distribution, degradation pathways, and ecological effects of microplastics in soil environments, highlighting threats to soil fauna, microbiota, and plant growth.
Microplastics in agroecosystems: A review of effects on soil biota and key soil functions
This review examines how microplastic and nanoplastic contamination in agricultural soils affects soil organisms and ecological functions. Researchers found that plastics enter farmland through multiple pathways including plastic mulch, sewage sludge, and irrigation water, and once present they alter soil properties and exhibit toxic behavior toward soil biota. The study identifies significant knowledge gaps about the long-term impacts of microplastic accumulation on agricultural productivity and food safety.
Microplastics in Agricultural Soils: An Emerging Threat to Soil Health, Microbial Ecology, Crop Productivity, and Food Safety
This review examines how microplastics accumulate in agricultural soils from sources like plastic mulch, sewage sludge, and atmospheric deposition. Researchers found that these particles can disrupt soil microbial communities, harm plant health, and potentially enter the human food chain. The study highlights the urgent need for mitigation strategies to address this growing but often overlooked form of pollution in farmland.
Current research trends on microplastics pollution and impacts on agro-ecosystems: A short review
This review summarizes current research on microplastic pollution in agricultural ecosystems, covering sources, effects, toxicity, and potential solutions. Researchers found that while most microplastic studies have focused on marine environments, agricultural soils are also significantly contaminated through sources like plastic mulch film, sewage sludge, and irrigation water, with potential impacts on soil health and crop production.
Source, migration and toxicology of microplastics in soil
This review compiles research on the sources, movement, and toxic effects of microplastics in soil ecosystems, an area that has received less attention than aquatic pollution.
