The distribution of per- and polyfluoroalkyl substances (PFAS), alkylphenols, organotin compounds, phthalates, alkylated polycyclic aromatic hydrocarbons, current-use pesticides (CUPs) and personal care products (PCPs) was characterized in 29 surface sediments from two Spanish Iberian continental shelf areas (14 on the Atlantic and 15 on the Mediterranean coasts). Concretely, 115 organic contaminants were determined and a specific methodology was used for each contaminant group, including contaminants of emerging concern (CECs) and traditional ones, such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorinated pesticides (OCPs). PAHs, alkylated PAHs, alkylphenols and phthalates were found in all samples, showing mean concentrations per group higher than 20 ng/g (16–4974 ng/g d.w.) in the subregions under consideration (Galician, Cantabrian, Levantine-Balearic and Strait-Alboran). CUPs and PCPs were found in the majority of samples at very low concentrations of ng/g (1.4–46.8 ng/g d.w.), whereas organotins and PFAS were found principally in sediments from the Mediterranean subregions (2.5–3.9 ng/g d.w.). Different distribution patterns were observed for the contaminant groups and subregions under consideration as a consequence of the diverse predominant sources (industrial, urban, transport and agricultural activities) and environmental behavior (mainly hydrophobicity and persistence). Risk assessment confirmed the impact of phthalates, alkylphenols, PAHs and PCBs on Atlantic ecosystems and of alkylphenols, chlorpyrifos, phthalates, TBT, PAHs, OCPs and PCBs on the Mediterranean ones. Furthermore, the presence of CUPs, PCPs and PFAS in sediments from the Spanish continental shelf located between 2 and 31 km from the coast suggested that those contaminants may also provoke adverse effects on coastal marine ecosystems between their sources and their depositional areas.

在西班牙大陆架沉积物中识别正在引起潜在环境风险的污染物。

每人的分布-和多氟烷基物质（PFAS），烷基酚，有机锡化合物，邻苯二甲酸盐，烷基化多环芳烃，当前使用的农药（CUPs）和个人护理产品（PCPs）的特征是来自两个西班牙伊比利亚大陆架地区的29个表层沉积物中大西洋和地中海沿岸的15个）。具体而言，确定了115种有机污染物，并针对每个污染物组使用了一种特定的方法，包括新兴关注的污染物（CEC）和传统污染物，例如多环芳烃（PAH），多氯联苯（PCB）和有机氯农药（OCP） 。在所有样品中都发现了多环芳烃，烷基化多环芳烃，烷基酚和邻苯二甲酸盐，显示所考虑的次区域中每组的平均浓度均高于20 ng / g（16–4974 ng / g dw）。Cantabrian，Levantine-Balearic和Strait-Alboran）。在大多数样品中都发现了很低的ng / g（1.4–46.8 ng / g dw）浓度的CUP和PCP，而有机锡和PFAS主要存在于地中海次区域的沉积物中（2.5–3.9 ng / g dw）。 。由于各种主要来源（工业，城市，运输和农业活动）和环境行为（主要是疏水性和持久性），所考虑的污染物组和次区域观察到了不同的分布方式。风险评估证实了邻苯二甲酸盐，烷基酚，多环芳烃和多氯联苯对大西洋生态系统的影响，以及烷基酚，毒死rif，邻苯二甲酸盐，TBT，多环芳烃，OCP和多氯联苯对地中海沿岸生态系统的影响。此外，存在银联，
