This work provides the first spatial distribution report of micropollutants (MPs) in the entire Portuguese coast, comprising the ocean shore (sea water, SW) and whenever possible the nearest river discharging on it (estuarine water, EW). This surface water monitoring programme aimed to assess the spatial distribution of 37 MPs with a wide chemical nature, including some substances prioritized by the European Union Directive 39/2013/EU and contaminants of emerging concern targeted in the Watch List of Decisions 495/2015/EU and 840/2018/EU. The risk quotients were estimated in each sampling point for the detected MPs. High concentrations of diclofenac, tramadol and carbamazepine were determined, the latter with medium to high risk for algae. Some pharmaceuticals and perfluorooctanesulfonic acid (PFOS) were broadly distributed, maybe due to the direct discharge into the sea. Atrazine and alachlor were found in the majority of the samples, with alachlor levels often considered as medium to high risk.
本研究首次提供了葡萄牙整个海岸地区（包括海洋岸线[海水，SW]和尽可能靠近的入海口[河口，EW]）中微污染物（MPs）的空间分布报告。该地表水监测计划旨在评估 37 种具有广泛化学性质的 MPs 的空间分布情况，包括欧盟指令 39/2013/EU 优先关注的一些物质，以及欧盟 Watch List 中 495/2015/EU 和 840/2018/EU 号决定中重点关注的新兴污染物。针对每个采样点检测到的 MPs 进行了风险商数的估算。结果表明，在大多数采样点都检测到了较高浓度的双氯芬酸、曲马多和卡马西平，其中卡马西平对藻类的风险处于中到高的水平。一些药物和全氟辛烷磺酸（PFOS）也有广泛的分布，这可能是由于它们直接排入了大海。阿特拉津和甲草胺在大多数样品中都有检出，其水平常被认为处于中到高风险。
