正确分配公路雨水径流中的金属负载到适当的来源，需要准确的数据源组成，特别是关于成分，有助于区分来源。从私人拥有的车辆和水提取物中收集了代表性的轮胎和制动器样品，分析了28种元素。相关主成分分析（PCA）显示，轮胎的影响最大的锌，铅，铜，而刹车最好的特点是钠和铁其次是钡，铜，镁，锰，钾;后三个可能是由于路边土壤的贡献。显着升高镉的贡献，发现在几个刹车样品。对目标镀镉制动盘进行采样，结果与较大样本人群中发现的升高水平一致。由于镉在水生生态系统中的高毒性，这种富集的镉来源特别令人关注。
Properly apportioning the loads of metals in highway stormwater runoff to the appropriate sources requires accurate data on source composition, especially regarding constituents that help to distinguish among sources. Representative tire and brake samples were collected from privately owned vehicles and aqueous extracts were analyzed for twenty-eight elements. Correlation principal components analysis (PCA) revealed that tires were most influenced by Zn, Pb, and Cu, while brakes were best characterized by Na and Fe followed by Ba, Cu, Mg, Mn, and K; the latter three may be due to roadside soil contributions. Notably elevated Cd contributions were found in several brake samples. A targeted Cd-plated brake rotor was sampled, producing results consistent with the elevated levels found in the larger sample population. This enriched source of Cd is of particular concern due to high toxicity of Cd in aquatic ecosystems.
