Air samples were collected in Venice during summer 2009 and 2012 to measure gas and particulate concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs). PCB-11, considered a marker for non-Aroclor contamination of the environment, was found for the first time in the Venetian lagoon and in Europe. An investigation on sources has been conducted, evidencing traffic as the major source of PAHs, whereas PCBs have a similar composition to Aroclor 1248 and 1254; in 2009 a release of PCN-42 has been hypothesized. Toxicological evaluation by TCA and TEQ methods, conducted for the first time in Venice air samples, identified BaP, PCB-126 and PCB-169 as the most important contributors to the total carcinogenic activity of PAHs and the total dioxin-like activity of PCBs and PCNs.
于 2009 年和 2012 年夏季在威尼斯采集空气样本，以测量多环芳烃（PAHs）、多氯联苯（PCBs）和多氯萘（PCNs）的气体和颗粒浓度。PCB-11 首次在威尼斯泻湖和欧洲被发现，被认为是环境中非 Aroclor 污染的标志物。已对污染源进行了调查，表明交通是 PAHs 的主要来源，而 PCBs 的组成与 Aroclor 1248 和 1254 相似；2009 年假设发生了 PCN-42 的释放。在威尼斯空气样本中首次进行的 TCA 和 TEQ 方法的毒理学评估确定 BaP、PCB-126 和 PCB-169 是 PAHs 总致癌活性和 PCBs 和 PCNs 总类二恶英活性的最重要贡献者。
