Tire particles (TPs) generated on roads are a main contributor to microplastic environmental pollution. In this study, TP leachates from three vehicle types (bicycle, car, and electric scooter) were prepared. TP leachate toxicity impacts on three organisms (Vigna radiata, Daphnia magna, and Danio rerio) were analyzed, in addition to their chemical compositions. Zinc and benzothiazole were the most commonly detected compounds in all three leachate types. Growth inhibition of V. radiata, mortality of D. magna, and abnormality in D. rerio were observed as toxicological impacts. Overall, the lethal effects of TP leachates showed a significant, positive relationship with zinc and benzothiazole concentration. The results confirmed that TPs are complex contaminants, which release chemicals into the environment that affect both soil and aquatic organisms. These findings highlight the need for stricter control measures and environmental regulations to mitigate the ecotoxic effects of TPs and related contaminants across ecosystems and trophic levels.
道路上产生的轮胎颗粒（TPs）是造成微塑料环境污染的主要因素。本研究制备了三种车型（自行车、汽车和电动滑板车）的 TP 浸出物。分析了 TP 浸出物对三种生物（豇豆、水蚤和斑马鱼）的毒性影响及其化学成分。锌和苯并噻唑是所有三种浸出物类型中最常见的化合物。观察到豇豆生长抑制、水蚤死亡和斑马鱼异常，这些都是毒理学影响。总的来说，TP 浸出物的致死效应与锌和苯并噻唑浓度呈显著正相关。研究结果证实，TPs 是复杂的污染物，它们会将化学物质释放到环境中，影响土壤和水生生物。这些发现强调了需要采取更严格的控制措施和环境法规，以减轻 TPs 及其相关污染物对生态系统和营养级的生态毒性影响。
