Microplastics in Soil Pose Global Threat by Acting Like ‘Trojan Horse’ to Deliver Toxins
Exclusive: Plastic surfaces form hotspots with an increase of antibiotic-resistant genes, study finds
TL;DR
- Microplastics have been found in all tested agricultural fields across 11 European countries.
- Microplastics act as 'Trojan horses,' delivering pollutants, pesticides, and bacteria through the soil.
- The 'plastisphere' on microplastic surfaces creates hotspots for microbes and agrochemicals, increasing antibiotic-resistant genes.
- Tyre-wear particles correlate with higher levels of toxic chemicals and metals in soil.
- Microplastics can disrupt nutrient cycles and negatively affect plant growth, with effects exacerbated by drought.
- Biodegradable plastics can also degrade into microplastics, posing ecological risks.
- Researchers call for standardized monitoring, manufacturer transparency, and risk assessments for microplastics.
