End-of-life tires are utilized for various purposes, including sports pitches and playground surfaces. However, several substances used at the manufacture of tires can be a source of concerns related to human health or environment's adverse effects. In this context, it is necessary to map whether this approach has the desired effect in a broader relation. While the negative effects on human health were investigated thoroughly and legislation is currently being revisited, the impact on aquatic or soil organisms has not been sufficiently studied. The present study deals with the exposure of freshwater and soil organisms to rubber crumb using the analysis of heavy metal and polycyclic aromatic hydrocarbon concentrations. The obtained results refer to substantial concerns related to freshwater contamination specifically, since the increased concentrations of zinc (7 mg·L) and polycyclic aromatic hydrocarbons (58 mg·kg) inhibit the growth of freshwater organisms, , and in particular. The performed test with soil organisms points to substantial concerns associated with the mortality of earthworms as well. The acquired knowledge can be perceived as a roadmap to a consistent approach in the implementation of the circular economy, which brings with it a number of so far insufficiently described problems.
废旧轮胎有多种用途，包括用于运动场地和操场地面。然而，轮胎制造过程中使用的几种物质可能会引发与人类健康或环境负面影响相关的问题。在这种情况下，有必要全面评估这种方法是否能产生预期效果。虽然对人类健康的负面影响已得到充分研究，且目前正在重新审视相关立法，但对水生生物或土壤生物的影响尚未得到充分研究。本研究通过分析重金属和多环芳烃浓度，探讨淡水和土壤生物接触橡胶颗粒的情况。所得结果表明，尤其值得关注淡水污染问题，因为锌（7毫克/升）和多环芳烃（58毫克/千克）浓度的增加会抑制淡水生物的生长，特别是[具体生物名称未给出]。对土壤生物进行的测试也表明，蚯蚓死亡率也存在重大问题。所获得的知识可被视为在实施循环经济过程中采取一致方法的路线图，而这也带来了一些迄今描述不足的问题。
