Distribution and Risk Assessment of Organophosphate Esters in Agricultural Soils and Plants in the Coastal Areas of South China
This study measured organophosphate esters, chemicals used as flame retardants and plasticizers in plastic products, in agricultural soils and crops along China's southern coast. These chemicals were found in every soil and plant sample tested, with some areas showing high ecological risk levels. While focused on chemical additives rather than microplastics directly, these are the same toxic compounds that leach from microplastics, showing how plastic-related chemicals contaminate the food supply.
Status, characteristics, and ecological risks of microplastics in farmland surface soils cultivated with different crops across mainland China
Researchers conducted a nationwide survey of microplastics in farmland soils across mainland China, covering over 30 crop types in 109 cities. They found microplastics in all sampled soils, with concentrations varying by crop type, region, and farming practices such as plastic film mulching and irrigation methods. The study provides the most comprehensive picture to date of agricultural microplastic contamination in China and identifies the key farming practices that contribute most to soil pollution.
Characteristics of organophosphate ester contamination and multiple influencing factors in various agricultural soils across China: A national-scale investigation
Researchers conducted a national-scale investigation of organophosphate ester (OPE) contamination across different agricultural land types in China, examining the influence of agronomic practices and environmental factors alongside co-occurring microplastics and phthalate esters. The study found OPEs widely distributed in farmland soils and identified key drivers of contamination levels including soil properties, cropping systems, and proximity to pollution sources.
The abundance, characteristics and distribution of microplastics (MPs) in farmland soil—Based on research in China
This review analyzed microplastic contamination in farmland soil across China and found that fertilizer use and plastic mulch film are the biggest contributors, increasing soil microplastic levels by 170% and 232% respectively. The most common types found were polyethylene and polypropylene fragments and fibers. These findings are concerning because microplastics in farm soil can be taken up by crops and enter the human food supply.
Accumulation and Transport of Phthalic Acid Esters in the Soil-Plant System of Agricultural Fields with Different Years of Film Mulching
Agricultural plastic mulch films release phthalate plasticizers (PAEs) into surrounding soil over time, and these chemicals accumulate in crops like maize and cabbage. After more than 10 years of continuous mulching, DEHP levels in cabbage leaves exceeded China's national food safety limits, highlighting a direct pathway for plastic-associated chemical contaminants to enter the human food supply.
[Distribution Characteristics and Risk Assessment of Microplastics in Farmland Soil in Guyuan].
Researchers analyzed microplastic distribution in agricultural soils in Guyuan City, China, finding concentrations ranging from 186 to 1,286 particles per kg, with greenhouse farming soils containing 35–229% more microplastics than open fields and PE and PP being the dominant polymer types. The findings raise concern for food chain contamination and demonstrate that plastic mulch film use in facility agriculture significantly increases soil microplastic accumulation.
The Source, Distribution Characteristics,and Migration Behavior of Microplastic Pollutionin Soil Environment in China: A Review
Researchers reviewed how microplastics enter Chinese soils — mainly through plastic mulch films, sewage irrigation, and fertilizer application — and how they migrate through soil layers while carrying other pollutants with them. The review highlights that China's intensive agricultural practices make its soils among the most microplastic-contaminated on Earth, with implications for food safety and groundwater quality.
Phthalate ester levels in agricultural soils of greenhouses, their potential sources, the role of plastic cover material, and dietary exposure calculated from modeled concentrations in tomato
Researchers measured phthalate plasticizer concentrations in soils across 50 greenhouses and modeled dietary exposure through tomatoes, finding that plastic cover materials and irrigation pipes are the dominant sources of soil phthalate contamination and that DEHP in greenhouse-grown tomatoes poses a measurable carcinogenic risk.
Potential sources and occurrence of macro-plastics and microplastics pollution in farmland soils: A typical case of China
This study provides the first comprehensive survey of plastic pollution in Chinese farmland soil, analyzing data from 163 publications covering 728 sites. The average microplastic abundance was 4,537 particles per kilogram of dry soil, with agricultural plastic films and organic waste being the biggest sources. Since China is the world's largest user of agricultural plastics, these findings highlight how farming practices can lead to significant microplastic contamination of the soil that grows our food.
The characteristics and influencing factors of farmland soil microplastic in Hetao Irrigation District, China
Researchers surveyed microplastic contamination in farmland soil across a major grain-producing region in China, finding concentrations ranging from about 1,800 to over 86,000 particles per kilogram. Polyethylene film fragments from agricultural plastic mulch were the dominant type, and 90% of the particles were smaller than 180 micrometers. The study shows that farming practices are introducing large amounts of microplastics into the soil where food crops are grown, raising questions about potential transfer into the food supply.
Agricultural plastic mulching as a source of microplastics in the terrestrial environment
Researchers analyzed 384 soil samples from 19 Chinese provinces and found that macroplastic fragments were concentrated in agricultural fields with plastic mulch film use, providing large-scale field evidence linking agricultural mulching to terrestrial plastic contamination.

Using data from over 3,000 field sites across China, researchers found that about 4.3% of soil ecosystems face ecological risk from microplastics, with agricultural soils being the most vulnerable at nearly 15%. Climate factors like temperature and precipitation, combined with human activities like plastic film use in farming, are the main drivers of risk. The study highlights that microplastic contamination in farm soil is a widespread problem that could affect the safety of crops grown for human consumption.

Researchers measured microplastic levels in agricultural soil, water, and fertilizer in a farming region of central China and found an average of about 4,500 particles per kilogram of soil. Over 90% of the particles were smaller than 100 micrometers, and the main types were polyethylene and PET from sources like plastic mulch and compost. The findings show that farming practices are introducing significant microplastic contamination into the soil where food is grown.
