Microplastic pollution in soil and groundwater: a review
Summary
This review examines microplastic contamination in soil and groundwater, which has received less attention than ocean pollution. Littering is the main source of soil microplastics globally, and fibers and pellets are the most common shapes found. The contamination is harmful to soil organisms like earthworms and nematodes, can alter soil properties, and poses potential risks to human health through groundwater used for drinking.
Plastic particles of less than 5 mm size, referred as microplastics, have recently become a major environmental issue. While microplastics are well known in marine and lake systems, there have been less investigations in soils and groundwater. Here we review the origin, shape, impact, and mitigation strategies of soil and groundwater microplastics. We found that littering is the main origin of microplastics in global topsoils, while greenhouses are the main source of microplastics in South Korea. Fibers and pellets are dominant microplastic shapes in soil and groundwater. Microplastic contamination of soil and groundwater is detrimental to human health, plants, nematodes, earthworms, and soil properties. Remediation methods include pyrolysis, replacing plastics by biodegradable plastics, plastic filtration, and subsequent chemical or biological degradation.

A review of microplastics in the soil environment
This review summarizes the current state of knowledge about microplastic contamination in soil environments, covering sources, distribution, and effects on soil organisms and ecosystems. The study highlights that while aquatic microplastic research is more advanced, soil contamination poses significant but understudied risks to terrestrial ecosystems and food production.
Microplastics in terrestrial ecosystems: sources, transport, fate, mitigation, and remediation strategies
This review examines how microplastics from urban, agricultural, and industrial sources are building up in soils worldwide. Wind, water, and soil organisms transport these particles across landscapes, where they persist and can affect soil structure and the health of living things. The authors highlight that land-based microplastic pollution has received far less attention than ocean pollution, despite its potential risks to ecosystems and human health through the food chain.
Global distribution, drivers, and potential hazards of microplastics in groundwater: A review
This review maps the global distribution of microplastics in groundwater and finds that contamination is widespread, with fiber-shaped particles and polyethylene being the most common types detected. The study highlights that climate change and local geology play underappreciated roles in how microplastics move through soil into groundwater, which is a drinking water source for billions of people worldwide.
How microplastics are destroying soil and human health
This review examined how microplastics harm soil health — disrupting soil structure, water retention, microbial communities, and nutrient cycling — and how soil degradation translates into risks for human health through food and water contamination. It argues that soil microplastic pollution deserves equivalent attention to aquatic contamination.
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.
