Tire particles are of concern as a stressor due to the combination of their chemical constituents, high emission rates, and global distribution. Once in the environment, they will interact with physical parameters (e.g., UV, temperature). The interaction of chemical pollution with changing physical environmental parameters is often underestimated in ecotoxicology. Here, we investigate the role of temperature, mechanical stress (i.e., turbulence), UV, and CO2 on the effects of tire leachates on fish. Two samples of tire particles were exposed to four different levels of each physical stressor. A toxicological assessment was performed with fathead minnow embryos assessing five end points (hatching success, time to hatch, length, deformities, and heart rate). Results showed that variations of temperature and mechanical stress affect the toxicological impact of tire leachates. Zn and/or polycyclic aromatic hydrocarbons (pyrene, phenanthrene, chrysene, benzo[a]pyrene, anthracene, naphthalene, fluoranthene, and benzo[ghi]perylene) were identified in the leachate and tire samples by Raman/surface-enhanced Raman spectroscopy and gas chromatography with mass spectroscopy, respectively.

升高的温度和湍流改变了轮胎颗粒中渗滤液对黑头Fat（Pimephales promelas）的影响。
轮胎颗粒由于其化学成分，高排放率和全球分布的综合考虑而成为压力源。一旦进入环境，它们将与物理参数（例如，紫外线，温度）相互作用。在生态毒理学中，经常低估了化学污染与不断变化的物理环境参数之间的相互作用。在这里，我们研究了温度，机械应力（即湍流），紫外线和二氧化碳对轮胎渗滤液对鱼类的影响的作用。将两个轮胎颗粒样品暴露于每种物理应力源的四个不同水平下。用黑头min鱼胚胎进行了毒理学评估，评估了五个终点（孵化成功，孵化时间，长度，畸形和心律）。结果表明，温度和机械应力的变化会影响轮胎渗滤液的毒理学影响。通过拉曼/表面增强拉曼光谱法和轮胎样品鉴定了浸出液和轮胎样品中的锌和/或多环芳烃（py，菲、,、苯并[a]]，蒽，萘，荧蒽和苯并g）。气相色谱法和质谱法。
