Automated high-throughput behavioral phenotyping reveals subtle ecotoxicity of tire wear particles in Drosophila larvae

Toxicity Effects of Microplastics and Tire Particles on Daphnia magna

The Potential Concentration-Dependent Effects of Tire Microplastics on the Earthworm Eisenia fetida

AI summary · Read the abstract

Researchers exposing earthworms (Eisenia fetida) to tire-derived microplastics at four concentrations found significant increases in antioxidant enzyme activity — including catalase, superoxide dismutase, and glutathione peroxidase — indicating oxidative stress and immune system activation at environmentally relevant exposure levels.

Toxicity assessment of environmentally relevant microplastics and tire particles on adult zebrafish (Danio rerio)

Drosophila fruit fly an in vivo model to determine hazardous effects following exposure to nanoplastics utilizing the One Health approach

AI summary · Read the abstract

Scientists used fruit flies to study how tiny plastic particles called nanoplastics, even smaller than microplastics, might harm living things, since flies share many basic biological traits with humans. This "One Health" approach connects the dots between environmental pollution, animal health, and human health, helping researchers understand how nanoplastic exposure could potentially affect our bodies too. As nanoplastics turn up more and more in our food, water, and air, this kind of research matters because it helps scientists figure out what health risks these invisible pollutants might actually pose to people.

Long-term sublethal exposure to polyethylene and tire wear particles: Effects on risk-taking behaviour in invasive and native fish

AI summary · Read the abstract

Fish that ate tiny amounts of plastic (from everyday items and tire dust that washes into waterways) for two months became bolder and took more risks, likely making them easier targets for predators. While this study looked at fish behavior rather than humans directly, it's a reminder that the plastic particles we're increasingly finding in water, soil, and food chains can quietly reshape how animals act and survive, raising questions about the broader ripple effects of plastic pollution on ecosystems we depend on.
