Tire wear particles - toxic for fish?

Tire wear particles - toxic for fish?

Experiments with gill cells and intestinal cells of rainbow trout show that the concentrations of tire wear particles found in the environment are not acutely toxic to fish. However, the chronic toxicity should be further investigated, as should the mechanism of action of the toxic oxidation product 6PPD-quinone.
