ClearInfluences of different source microplastics with different particle sizes and application rates on soil properties and growth of Chinese cabbage (Brassica chinensis L.)
Researchers tested how two types of microplastics at different sizes and concentrations affect soil properties and the growth of Chinese cabbage. They found that smaller particles at higher concentrations altered soil enzyme activity and reduced plant growth, though the effects depended on the specific plastic type. The study suggests that microplastic contamination in agricultural soils could meaningfully impact crop productivity and soil health.
Novel insights related to soil microplastic abundance and vegetable microplastic contamination
Researchers analyzed microplastic contamination in farmland soils and the vegetables grown in them, finding that polyethylene and polypropylene were the most common plastic types in soil. Chinese cabbage had the highest vegetable contamination levels, and there was a moderate correlation between soil and vegetable microplastic concentrations. The study provides real-world evidence that microplastics in agricultural soil can transfer into the food crops people eat.

Five microplastic types were tested on non-heading Chinese cabbage seed germination, finding PVC and PET had the greatest inhibitory effects on germination, while PVC and PP promoted growth of germinated seeds at certain concentrations.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
Brassica sprouts exposed to microplastics: Effects on phytochemical constituents
Brassica sprouts grown in soil containing microplastics at varying concentrations showed changes in secondary metabolite profiles and reduced accumulation of key bioactive compounds including glucosinolates and antioxidants. The results suggest that microplastic contamination of agricultural soils can alter the nutritional and phytochemical quality of edible crops.
Microplastics Can Change Soil Properties and Affect Plant Performance
Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.

Microplastics in soil differentially interfere with nutritional aspects of chilli peppers
Growing chilli peppers in soil contaminated with five different microplastic types — including PVC, PS, HDPE, LDPE, and PET — significantly reduced nutritional quality, with PVC causing the greatest losses in protein, vitamins A and B6, and fatty acids. This research demonstrates a direct pathway by which soil microplastic pollution could degrade the nutritional value of food crops, with implications for food security and human health.
The response of Chinese Cabbage (Brassica rapa L.) to the co-contamination of nanoplastics with different polarity and Ketoprofen
Researchers grew Chinese cabbage in soil contaminated with polyethylene and polypropylene nanoparticles alone and in combination with the pharmaceutical ketoprofen. Both nanoparticle types reduced plant biomass and caused oxidative stress, with polypropylene being more toxic because it translocated from roots to aerial parts, and the combination with ketoprofen intensified all harmful effects.
