Phthalates are an emerging class of environmental pollutants whose distribution and effects in aquatic environments are not well characterized. We analyzed intertidal and emerged beach sediments from the Abruzzo coastline, along the Adriatic Sea, finding significant phthalate concentrations in marine sediments. Phthalate baseline levels in the intertidal environment, marked by substantial interplay of sediment, water and air, were determined. We used statistical rank methods to select representative phthalate compositions, for which we derived risk levels for ingestion, dermal absorption and inhalation. Our study shows that phthalates are a major cause of pollution along the Abruzzo coast, with river transport of sediments a continuous source of replenishment. Phthalate concentrations in two specific sites were determined to be of the same order of magnitude as the safety, remediation-warranting, threshold set by Italian law. Phthalates, heavy metals, PAHs appear to be correlated. We discuss possible intervention and mitigation strategies.
邻苯二甲酸酯是一类新兴的环境污染物，其在水生环境中的分布和影响尚未得到很好的描述。我们分析了亚得里亚海阿布鲁佐海岸的潮间带和出露海滩沉积物，发现海洋沉积物中存在显著的邻苯二甲酸酯浓度。在潮汐环境中确定了邻苯二甲酸酯的基线水平，这一环境中沉积物、水和空气之间存在大量相互作用。我们使用统计等级方法选择具有代表性的邻苯二甲酸酯成分，并据此得出摄入、皮肤吸收和吸入的风险水平。我们的研究表明，邻苯二甲酸酯是阿布鲁佐海岸污染的主要原因，河流输送的沉积物是不断补充的来源。两个特定地点的邻苯二甲酸酯浓度被确定处于与意大利法律规定的安全、需要修复的阈值相同的数量级。邻苯二甲酸酯、重金属、多环芳烃似乎存在相关性。我们讨论了可能的干预和缓解策略。
