dc.description - en: Tire wear particles (TWPs) are tiny bits that rub off tires as we drive. They end up in water and can release both chemicals and nanoparticles, which may harm aquatic life. In this study, we tested how these different components affect algae, duckweed, and water fleas—three common freshwater organisms. Water fleas were the most sensitive and were harmed by both the chemicals and the nanoparticles, especially when combined. Duckweed was affected mainly by the dissolved chemicals, which reduced its ability to photosynthesize. Algae showed only mild effects. Overall, the study shows that nanoparticles in tire pollution can be just as harmful as the chemicals themselves.
dc.description.abstract - en: Tire wear particle (TWP) contamination is of growing concern as recent studies show the ubiquity and toxicity of this contaminant in various environmental compartments. The multidimensional aspect of TWPs makes it difficult to assess toxicity and predict impacts on ecosystems, as it combines a complex mixture of chemicals and can release micro- and nanoparticles when suspended in water. Our work aimed to shed light on the toxicity of the different components of TWP leachate, namely, the dissolved chemicals and the nanoparticle fractions, on three freshwater model species of different trophic levels: Chlorella vulgaris, Lemna minor, and Daphnia magna. Acute toxicity was observed for all three fractions in D. magna, and an additive effect was observed between the nanoparticles and dissolved chemicals. L. minor experienced phytotoxicity from the dissolved chemicals only with a decrease up to 50% in photosynthesis efficiency parameters. C. vulgaris showed minor signs of toxicity on apical endpoints in response to each of the fractions. Our study highlights that nanoparticles from TWP leachate that were mostly overlooked in several previous studies are as toxic as dissolved chemicals for the filter-feeder species D. magna, and we also show the toxicity to photosynthesis in aquatic plants.
dc.description.fosrctranslation - fr: Les particules d'usure des pneus (TWPs) sont de minuscules fragments qui se détachent des pneus lorsque nous conduisons. Elles finissent dans l'eau et peuvent libérer des produits chimiques et des nanoparticules, qui peuvent nuire à la vie aquatique. Dans cette étude, nous avons testé l'effet de ces différents composants sur les algues, les lentilles d'eau et les puces d'eau, trois organismes d'eau douce courants. Les puces d'eau se sont révélées les plus sensibles et ont été affectées à la fois par les produits chimiques et les nanoparticules, en particulier lorsqu'ils étaient combinés. Les lentilles d'eau ont été principalement affectées par les produits chimiques dissous, qui ont réduit leur capacité à photosynthétiser. Les algues n'ont montré que des effets légers. Dans l'ensemble, l'étude montre que les nanoparticules présentes dans la pollution des pneus peuvent être tout aussi nocives que les produits chimiques eux-mêmes.
