Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous global pollutants that are lipophilic, bioaccumulative and can be both endocrine disruptors and carcinogens. In this study, we measured 18 PAHs among decapod shrimp samples (Palaemon spp.) collected during the spring and autumn from multiple locations along the Portuguese coastal, including local markets and aquaculture farms. ΣPAH concentrations in samples ranged from 3.14 to 320.48 ng/g (ww) with the highest value in this range detected in a sample provided from an aquaculture facility. Fifteen of the 18 scanned PAHs were present in shrimp samples. However, detectable concentrations (0.07 ng/g ww) of the carcinogenic benzo-a-pyrene occurred for a single sample only and approached method detection limits. No significant differences in shrimp ΣPAH concentrations were evident between the spring and autumn seasons. Target hazard quotient estimation suggested low probability of adverse health effects to consumers through consumption of shrimp from the study collection locations.

葡萄牙沿海十足目虾中多环芳烃的季节和空间比较

多环芳烃 (PAHs) 是普遍存在的全球污染物,具有亲脂性、生物累积性,并且可能是内分泌干扰物和致癌物。在这项研究中,我们测量了十足目虾样本(Palaemon )中的 18 种 PAHspp.) 在春季和秋季从葡萄牙沿海的多个地点收集,包括当地市场和水产养殖场。样本中的 ΣPAH 浓度范围为 3.14 至 320.48 ng/g (ww),在该范围内的最高值是在水产养殖设施提供的样本中检测到的。18 种扫描的 PAH 中有 15 种存在于虾样品中。然而,致癌苯并-a-芘的可检测浓度 (0.07 ng/g ww) 仅出现在单个样品中,并接近方法检测限。春季和秋季之间虾的 ΣPAH 浓度没有明显差异。目标危害商估计表明,通过食用研究采集地点的虾对消费者产生不利健康影响的可能性很小。
