The Gulf of Milazzo (north-eastern Sicily) has been recognized as Italian Site of National Interest (SNI; areas characterized by high level of contamination with potential effects on human health) in 2005 because of its high level of pollution. In this study we measured the concentration of polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), and polyBrominated diphenyl ether (PBDE) in seawater and sediments sampled from the Gulf of Milazzo in order to assess (i) the environmental status of contamination, and (ii) cancer and non-cancer human health risk potentially due to dermal absorption from contaminated seawater and/or ingestion of contaminated fish. Particularly, POPs content in pelagic and demersal fish of different size classes (small, medium, and large) were estimated, starting from the measured seawater and sediments concentrations, using the KABAM model. In particular, Monte Carlo simulation techniques were applied to address uncertainty in assessment of the risk and to provide quantitative estimates of probability of exposition. Ingestion of contaminated pelagic and demersal fish was the dominant pathway of exposition with high probability of significant cancer risk (Ingestion Cancer Risk >10–4) and significant non-cancer risk (Hazard Index >1). No human health risks emerged to be associated to dermal adsorption from contaminated seawater. Benzo(a)pyrene show the highest Ingestion Cancer Risk with respect to the other PAHs, while the highest Hazard Index for non-cancerogenic molecules was estimated for the PBDE47 congener.

米拉佐湾(意大利南部)海洋沿海环境中的持久性和新兴有机污染物:人类健康风险评估

米拉佐湾(西西里岛东北部)因其高度污染而于 2005 年被认定为意大利国家利益遗址(SNI;以高度污染对人类健康有潜在影响的地区为特征)。在这项研究中,我们测量了从米拉佐湾采样的海水和沉积物中多环芳烃 (PAH)、有机氯农药 (OCP) 和多溴联苯醚 (PBDE) 的浓度,以评估 (i) 污染的环境状况,和 (ii) 癌症和非癌症人类健康风险可能是由于皮肤从受污染的海水中吸收和/或摄入受污染的鱼。特别是,估计了不同尺寸等级(小型、中型和大型)的中上层和底栖鱼类的持久性有机污染物含量,从测量的海水和沉积物浓度开始,使用 KABAM 模型。特别是,蒙特卡罗模拟技术被应用于解决风险评估中的不确定性,并提供暴露概率的定量估计。摄入受污染的中上层和底层鱼类是显着癌症风险(摄入癌症风险 >10-4)和显着非癌症风险(危害指数 >1)的主要暴露途径。没有发现与皮肤从受污染的海水中吸附有关的人类健康风险。与其他 PAH 相比,苯并 (a) 芘显示出最高的摄入致癌风险,而估计 PBDE47 同源物的非致癌分子的最高危险指数。蒙特卡罗模拟技术被应用于解决风险评估中的不确定性,并提供暴露概率的定量估计。摄入受污染的中上层和底层鱼类是显着癌症风险(摄入癌症风险 >10-4)和显着非癌症风险(危害指数 >1)的主要暴露途径。没有发现与皮肤从受污染的海水中吸附有关的人类健康风险。与其他 PAH 相比,苯并 (a) 芘显示出最高的摄入致癌风险,而估计 PBDE47 同源物的非致癌分子的最高危险指数。蒙特卡罗模拟技术被应用于解决风险评估中的不确定性,并提供暴露概率的定量估计。摄入受污染的中上层和底栖鱼类是显着癌症风险(摄入癌症风险 >10-4)和显着非癌症风险(危害指数 >1)的主要暴露途径。没有发现与皮肤从受污染的海水中吸附有关的人类健康风险。与其他 PAH 相比,苯并 (a) 芘显示出最高的摄入致癌风险,而估计 PBDE47 同源物的非致癌分子的最高危险指数。摄入受污染的中上层和底层鱼类是显着癌症风险(摄入癌症风险 >10-4)和显着非癌症风险(危害指数 >1)的主要暴露途径。没有发现与皮肤从受污染的海水中吸附有关的人类健康风险。与其他 PAH 相比,苯并 (a) 芘显示出最高的摄入致癌风险,而估计 PBDE47 同源物的非致癌分子的最高危险指数。摄入受污染的中上层和底层鱼类是显着癌症风险(摄入癌症风险 >10-4)和显着非癌症风险(危害指数 >1)的主要暴露途径。没有发现与皮肤从受污染的海水中吸附有关的人类健康风险。与其他 PAH 相比,苯并 (a) 芘显示出最高的摄入致癌风险,而估计 PBDE47 同源物的非致癌分子的最高危险指数。
