Abstract Regulations, definitions, and calculations related to emissions of Volatile Organic Compounds (VOC) from paints used for horizontal road markings (traffic paints) in North America and in European Union are different, which frequently makes simple comparisons impossible. To illustrate the dissimilarities, solvent packages of various exemplary paints that meet several normative requirements were compared for the nominal emissions according to different calculation procedures. For a unified assessment, volatile portions of the paints were evaluated based on Ozone Formation Potential (OFP). The analysis revealed that similar nominal VOC contents can lead to vastly different OFP, in an extreme case six times higher. Incongruously high OFP, which was calculated for emissions in Southern California despite strict limits can thus be explained. The provided calculations can be used by road administrators as a tool to demand materials with lowest environmental impact, by environmental researchers to pinpoint irregularities between declared and measured discharges, and can assist formulating chemists in selection of raw materials to prepare environmentally friendly road marking paints.

道路标线漆中挥发性有机化合物的排放

摘要 北美和欧盟与用于水平道路标线（交通油漆）的油漆中挥发性有机化合物 (VOC) 排放相关的法规、定义和计算不同，这常常使简单的比较变得不可能。为了说明不同之处，根据不同的计算程序，对满足若干规范要求的各种示例性涂料的溶剂包的标称排放进行了比较。为了统一评估，根据臭氧形成潜力 (OFP) 评估涂料的挥发性部分。分析表明，相似的标称 VOC 含量会导致大不相同的 OFP，在极端情况下会高出六倍。因此可以解释不协调的高 OFP，尽管有严格的限制，但它是为南加州的排放计算的。
