Microplastics in Sludges and Soils: A Comprehensive Review on Distribution, Characteristics, and Effects
This review summarizes research on microplastics in sewage sludge and soil, noting that when contaminated sludge is used as fertilizer, it turns farmland into a major reservoir for microplastic pollution.

Microplastics pollution modulating soil biological health – A review
This review summarizes how microplastics enter agricultural soil through recycled water, fertilizer made from sewage, and plastic mulch, and how they affect the organisms that keep soil healthy. Microplastics can carry chemical additives and environmental pollutants that harm soil bacteria, fungi, and invertebrates. These disruptions to soil health could affect crop growth and food quality, creating an indirect pathway for microplastics to impact human nutrition.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.
A discussion of microplastics in soil and risks for ecosystems and food chains
This review examines how microplastics accumulate in soils through agricultural practices, landfills, and wastewater, posing risks to ecosystems and food chains. Researchers found that while marine microplastic pollution has been well studied, terrestrial contamination remains poorly understood despite soil receiving more plastic waste than oceans. The study highlights how microplastics can alter soil properties, harm soil organisms, and potentially transfer through the food chain to humans.
Microplastics as contaminants in the soil environment: A mini-review
This mini-review examines microplastic contamination in soil environments, an area that has received far less attention than marine pollution. Researchers found that agricultural practices like plastic mulch use and sewage sludge application are major sources of soil microplastics. The study highlights that soil microplastics can harm plant growth, alter soil organisms, and potentially enter the food chain through crop uptake.
Microplastic contamination in soil environment – a review
This review examines the sources, transport, degradation, and ecological impacts of microplastic contamination in soil environments. The study suggests that soil acts as both a major sink for microplastics and a conduit transporting them to aquatic systems, and that microplastics can negatively affect soil organisms and biogeochemistry, underscoring the need for more research on terrestrial microplastic pollution.
Microplastics as pollutants in agricultural soils
This review examines how microplastics end up in agricultural soils through sewage sludge application, wastewater irrigation, plastic mulch films, and atmospheric deposition. Researchers found that microplastics interact with soil organisms and can alter soil structure and microbial communities, but standardized detection methods are still lacking. The study highlights the need for research on how microplastics move through soil, their effects on crop health, and global policies to address this growing agricultural concern.
Distribution, sources, migration, influence and analytical methods of microplastics in soil ecosystems
This review covers the sources, movement patterns, environmental effects, and detection methods for microplastics in soil ecosystems worldwide. Researchers found that agricultural practices including plastic mulch films, sewage sludge application, and irrigation with treated wastewater are major contributors to soil microplastic contamination. The study notes that terrestrial microplastic pollution may actually exceed ocean contamination but has received far less research attention.
Microplastics and nanoplastics in soil: Sources, impacts, and solutions for soil health and environmental sustainability
This review examines how microplastics and nanoplastics enter soil through farming activities, sewage sludge, and air deposition, and how they affect soil structure, water retention, and nutrient availability. The tiny plastic particles can harm beneficial soil microorganisms and potentially enter the food chain through crops, raising concerns about long-term impacts on both soil health and human well-being.
Significance of Microplastics in Agricultural Soil
This review examines the significance of microplastic contamination in agricultural soils, estimating it contributes approximately 20% of total plastic pollution in terrestrial ecosystems. Microplastics enter farmland through irrigation, mulch, and sewage sludge, and can be transported deeper into soil by plant roots and soil organisms. The accumulation of microplastics in agricultural land poses risks to soil health and the food grown in it.
Microplastics in agricultural soils: sources, impacts, and mitigation strategies
This review summarizes how microplastics enter agricultural soils through wastewater irrigation, plastic mulch breakdown, and atmospheric deposition, where they alter soil structure, microbial communities, and water retention. The particles can also carry heavy metals and organic pollutants into the food chain, threatening both crop productivity and human health, making it important to reduce plastic use in farming and improve waste management.
What Do We Know About the Effects of Microplastics on Soil?
This review examines the effects of microplastics on soil ecosystems, covering how mulching, wastewater irrigation, sludge application, and atmospheric deposition introduce microplastics to soil, where they alter physicochemical properties, affect microbial communities, and carry co-pollutants.
Effects of microplastics on the terrestrial environment: A critical review
This review summarizes what is known about microplastic contamination in land-based environments, covering sources, fate, and effects on soil and the organisms that depend on it. Microplastics in soil can interact with pesticides, heavy metals, and other pollutants, acting as carriers that move toxins through the food web and potentially up to humans. The authors note that compared to ocean research, the effects of microplastics on land ecosystems are much less studied and urgently need more attention.
How microplastics are destroying soil and human health
