Tire Wear Particle and Leachate Induce Oxidative Stress and Reshape the Rice Rhizosphere Soil System: Multi-Omics Evidence of Tissue-Specific Phytotoxicity

Tire wear particle and leachate induce oxidative stress and reshape the rice rhizosphere soil system: Multi-omics evidence of tissue-specific phytotoxicity

AI summary · Read the abstract

Tiny particles that wear off car and truck tires are washing into soil and, this study finds, they can stress rice plants at high concentrations—damaging roots, disrupting their internal chemistry, and shifting the balance of soil microbes that plants depend on. Since rice is a staple food for billions, this raises questions about whether tire pollution building up in farmland soils could eventually affect crop health and food supplies, making it an environmental issue worth watching even though this study didn't directly test human health effects.

Integrating metabolomics and high-throughput sequencing to investigate the effects of tire wear particles on mung bean plants and soil microbial communities.

Tire wear particles at realistic concentrations (0.1-1.5% soil weight) inhibited mung bean growth, altered root metabolite profiles, and shifted soil microbial community structure, indicating that road-derived plastic contaminants can disrupt soil-plant systems in agricultural settings.

Impact of tire particles and tire leachate contaminants on plant physiology and soil health: Case study in mung bean and tomato

AI summary · Read the abstract

Researchers compared how tire particles and tire leachate affect two crop species, finding that tomatoes mount a successful antioxidant defense and maintain growth while mung beans suffer severe oxidative damage and chlorophyll loss, and that the water-soluble leachate fraction poses the greatest acute risk — underscoring the need for species-specific risk assessment of tire-derived pollution near agricultural land.

The Influence of Microplastics from Ground Tyres on the Acute, Subchronical Toxicity and Microbial Respiration of Soil
