Single and combined effects of secondary polyethylene microplastic on the growth of Pak choi and the soil microbiome composition
AI summary Read the abstract
Researchers found that secondary polyethylene microplastics (aged via weathering and mechanical stress) significantly inhibited Pak choi growth, caused oxidative damage to plant cells, and altered soil microbial composition, while showing antagonistic combined effects with DDT and naphthalene due to MP adsorption of co-contaminants. Agriculturally realistic aged PE microplastics harm food crops and disrupt the soil microbiome, with soil chemical properties changing in ways that could affect long-term agricultural productivity.
Impact of Microplastic Accumulation on Rhizosphere Activities in Soil
AI summary Read the abstract
Researchers examine how microplastic accumulation in soil alters rhizosphere dynamics, finding that plastic particles disrupt microbial communities and enzyme activities in the root zone, with downstream effects on nutrient cycling and overall soil health.
The effects of different types microplastics on soil properties and the biochemistry of Chinese cabbage under different dosages and exposure times
AI summary Read the abstract
Microplastics from packaging and other plastic waste are building up in farm soils, and this study found that they can change soil quality and stress out crops like Chinese cabbage, altering nutrients, water content, and the plant's natural defense systems, especially at high concentrations. While this research looked at soil and plant health rather than testing the cabbage for human safety, it's a reminder that the plastic pollution we create doesn't just disappear, it may be quietly affecting the soil that grows our food.
Microplastics in soil-plant system: effects of nano/microplastics on plant photosynthesis, rhizosphere microbes and soil properties in soil with different residues
AI summary Read the abstract
Polystyrene micro- and nanoplastics altered soil dissolved organic matter, disrupted rhizosphere microbial communities, and affected plant photosynthesis in Chinese cabbage, with effects varying by plastic particle size and soil amendment type. These findings reveal that microplastic contamination can cascade through soil microbiomes to impair crop growth, raising concerns for agricultural productivity and food system safety.
Influences of microplastics alone and co-contaminated with cadmium on physiological responses of Chinese cabbage ( Brassica campestris L.), rhizosphere microbes and soil properties in soil
AI summary Read the abstract
Scientists tested how plastic pollution (microplastics) and cadmium, a toxic heavy metal, affect Chinese cabbage grown in contaminated soil, both matter because they can build up in crops we eat and impact human health. Surprisingly, small-to-moderate amounts of microplastics actually helped protect the cabbage from cadmium's harmful effects by changing soil chemistry and boosting helpful soil microbes, though this doesn't mean microplastic pollution is safe overall. This research shows the relationship between plastic pollution and toxic metals in soil is complicated, and more study is needed before we underst
