Combined pollution of soil by heavy metals, microplastics, and pesticides: Mechanisms and anthropogenic drivers
AI summary Read the abstract
This study investigated how heavy metals, microplastics, and pesticides interact when they contaminate soil together, finding that their combined effects are complex and often worse than any single pollutant. Microplastics can absorb and concentrate both heavy metals and pesticides, changing how these chemicals move through soil and into plants. The findings highlight how agricultural soils contaminated with multiple pollutants could increase human exposure through crops grown in that soil.
Soil is the foundation of terrestrial ecosystems and a critical resource for agricultural activities. This study investigated internal mechanism and interaction of heavy metals, pesticides (atrazine, pyrimazole and chlorpyrifos) and microplastics in soil. Specifically, certain sampling points exhibited elevated levels of individual heavy metals (Cd, Cr, Zn), exceeding the screening values, while both microplastics and pesticides demonstrated high variability, increasing the potential ecological risks. The interaction between microplastics, heavy metals, and pesticides is complex, involving electrostatic adsorption, surface complexation, biofilm mediation, and physical absorption. From a broader perspective, both heavy metals and microplastics were found to exacerbate the ecological risks posed by pesticides. Further, structural equation model and geographical weighted regression were used to reveal the driving mechanism behind complex pollution, with economic development emerging as a significant factor influencing pollution levels. These findings enhance our understanding of the combined pollution of heavy metals, microplastics, and pesticides.

Interactions among Heavy Metals, Microplastics and Pesticides in Soil and Advances in Microbial Remediation
AI summary Read the abstract
Tiny plastic bits in farm soil don't just pollute on their own—they can grab onto heavy metals and pesticides, making these toxins travel farther, last longer, or become more harmful together than any one pollutant alone, which matters since this soil grows the food we eat. This review pulls together existing research on how these three pollutants interact, and highlights promising work using soil bacteria and plants to break down or neutralize this combined contamination. The main takeaway: scientists still don't fully understand how these pollutants team up in real-world conditions, so more research is needed before we can reliably clean up farmland facing this triple threat.

A critical review of co-pollution of microplastics and heavy metals in agricultural soil environments
AI summary Read the abstract
This review examines how microplastics and heavy metals frequently occur together in agricultural soil, where they interact in ways that can increase the toxicity of both. These co-contaminants can harm soil organisms, reduce crop productivity, and potentially enter the human food chain, making their combined presence in farmland a growing concern for food safety and health.
