This work provides the first quantitative measure of flux of semi-volatile contaminants on artificial turf fields. Passive samplers were used to identify gas-phase PAHs and OPAHs not previously reported associated with artificial turf. Utilizing a broad and targeted screen, we assess both artificial turf and from crumb rubber for 1,529 chemicals, including several with known health effects including benzo[c]fluorene. We also report the presence of 25 chemicals that have not yet been reported in artificial turf literature, including some with known effects on human health. This is the first report of bioavailable gas-phase PAH and OPAH concentrations on an outdoor field, to date gas-phase concentrations have only been reported from indoor facilities. Turf air and air were highly correlated at all three sites, and particularly at the recently-installed indoor site. Finally, thermal extraction and silicone passive samplers are highly suitable for larger-scale sampling campaigns that aim for less solvent and sample processing. We demonstrate for the first time that silicone passive samplers can be used to quantify volatile and semi-volatile organic chemicals from artificial turf. Co-deploying silicone passive samplers and conventional low density polyethylene, we develop partitioning coefficients that can be used for silicone passive air sampling environmental assessment.
这项工作首次对人造草皮场地中半挥发性污染物的通量进行了定量测量。使用被动采样器来识别先前未报道过的与人工草皮相关的气相多环芳烃和氧化多环芳烃。通过广泛且有针对性的筛选，我们评估了人造草皮和碎橡胶中的1529种化学物质，其中包括几种已知对健康有影响的物质，如苯并[c]芴。我们还报告了在人造草皮文献中尚未报道过的25种化学物质的存在，其中一些对人类健康有已知影响。这是关于室外场地中生物可利用气相多环芳烃和氧化多环芳烃浓度的首次报告，迄今为止，气相浓度仅在室内设施中被报道过。在所有三个场地，草坪空气和空气高度相关，尤其是在最近安装的室内场地。最后，热萃取和硅胶被动采样器非常适合旨在减少溶剂和样品处理的大规模采样活动。我们首次证明硅胶被动采样器可用于量化人造草皮中的挥发性和半挥发性有机化学物质。通过共同部署硅胶被动采样器和传统的低密度聚乙烯，我们得出了可用于硅胶被动空气采样环境评估的分配系数。
