An effective, quick, and sustainable air analysis method was developed to analyze 41 volatiles and semivolatile organic compounds present in tire rubber and crumb rubber materials. The proposed method, based on active sampling using a sorbent material followed by an ultrasound assisted extraction, was developed with the aim of obtaining a fast and simple procedure to determine polycyclic aromatic hydrocarbons, plasticizers, antioxidants, and vulcanization agents in air. A small amount of sorbent (25 mg) was used, and the analytes were recovered in only 1 mL of solvent. An experimental design was applied to study the influence of main factors such as type of sorbent and type of solvent, extraction technique (ultrasound‐assisted extraction and vortex extraction), extraction time, as well as the factor interactions. Under optimal conditions, no breakthrough occurs in the studied interval (up to 4 m³). Linearity was demonstrated in a wide concentration range. Accuracy of the total sampling‐extraction analysis was evaluated obtaining satisfactory recoveries as well as good precision. The method was successfully applied to different outdoor and indoor air environments, including a recycled rubber synthetic turf football pitch.

微型主动空气采样法分析室内外轮胎橡胶污染物

开发了一种有效，快速和可持续的空气分析方法，用于分析轮胎橡胶和粒状生胶材料中存在的41种挥发性物质和半挥发性有机化合物。提出的方法是基于使用吸附剂材料进行主动采样，然后进行超声辅助萃取的方法，目的是获得一种快速简便的方法来测定空气中的多环芳烃，增塑剂，抗氧化剂和硫化剂。使用了少量的吸附剂（25 mg），并且仅在1 mL溶剂中回收了分析物。应用实验设计研究了主要因素的影响，例如吸附剂的类型和溶剂的类型，萃取技术（超声辅助萃取和涡旋萃取），萃取时间以及因素之间的相互作用。在最佳条件下³）。在很宽的浓度范围内都显示出线性。评估了总采样提取分析的准确性，获得了令人满意的回收率和良好的精密度。该方法已成功应用于不同的室外和室内空气环境，包括再生橡胶合成草皮足球场。
