Different specimens of Mullus surmuletus from the Catania Gulf (Sicily) were sampled and analysed for the quantification of 16 priority polycyclic aromatic hydrocarbons (PAHs) in order to evaluate the distribution of these pollutants and the potential human health risks associated to the consumption of fish. The determined PAHs concentration values ranged from 0.25 to 6.10 ng/g wet weight and the most abundant PAHs detected were lower molecular weight (LMW) compounds with 2 to 3 rings. Relying on the PAHs concentration values, on the consumption data and on the total toxic equivalent (TEQ), the incremental lifetime cancer risk (ILCR) was assessed and its calculated value (2.97 × 10) is far below the "maximum acceptable risk level" (ARL), suggesting a low potential carcinogenic risk on consuming M. surmuletus for local population. Even though the study shows a quite low contamination level in M. surmuletus, intensive monitoring programmes are still highly needed in order to provide a better picture of the PAHs distribution in Catania Gulf and of the human health risk linked to fish consumption.
从西西里岛卡塔尼亚湾采集了不同的蓝圆鲹样本，并对其进行了 16 种优先多环芳烃（PAHs）的定量分析，以评估这些污染物的分布情况，以及与食用鱼类相关的潜在人体健康风险。所测定的 PAHs 浓度值范围为 0.25 至 6.10ng/g 湿重，检出的最丰富的 PAHs 为低分子量（LMW）化合物，具有 2 至 3 个环。根据 PAHs 浓度值、消费数据和总毒性等效（TEQ），评估了增量终生癌症风险（ILCR），其计算值（2.97×10）远低于“最大可接受风险水平”（ARL），表明当地居民食用蓝圆鲹的致癌风险较低。尽管研究表明蓝圆鲹的污染水平相当低，但仍需要进行密集的监测计划，以便更好地了解卡塔尼亚湾 PAHs 的分布情况，以及与鱼类消费相关的人类健康风险。
