As the final part of a Europe-wide study on the risk from synthetic turf infill consisting of rubber granules derived from end-of-life tyres (ELT), exposure of sportspeople was assessed and compared with health-based reference values for various chemical substances. Based on information from previous project phases, exposure scenarios were established and exposure was calculated for oral, dermal and inhalation routes. Calculated cancer risks for exposure to polycyclic aromatic hydrocarbons were below 1:1 million. Risk characterisation ratios (RCRs) for non-carcinogenic substances were below 1, indicating no health concerns. For 2-hydroxybenzothiazole no toxicological data were found from which to derive a substance-specific reference value. A threshold-of-toxicological concern approach revealed maximum RCRs slightly above 1, which are acceptable, given the conservativism of the approach. ERASSTRI substantially improved the data available for assessing human health risks from using ELT-derived infill material. Overall, no health concerns could be identified for the use of synthetic turfs with ELT-derived infill material.
作为一项欧洲范围内的研究的最后部分，该研究旨在评估由废旧轮胎（ELT）衍生的橡胶颗粒制成的合成草皮填充物的风险，并将运动员的暴露情况与各种化学物质的基于健康的参考值进行比较。基于前几个项目阶段的信息，建立了暴露情景，并计算了口腔、皮肤和吸入途径的暴露情况。多环芳烃暴露的致癌风险低于 1:100 万。非致癌物质的风险特征比值（RCR）低于 1，表明没有健康问题。对于 2-羟基苯并噻唑，没有发现毒理学数据来推导特定物质的参考值。基于毒理学关注阈值的方法显示，最大 RCR 略高于 1，这是可以接受的，因为该方法具有保守性。ERASSTRI 大大改善了评估使用 ELT 衍生填充材料对人类健康风险的数据。总体而言，使用 ELT 衍生填充材料的合成草皮不会对健康造成任何担忧。
