Synthetic progestins are micropollutants of special concern, due to their growing use in human and veterinary therapies and their risks to aquatic life. Currently, there is a lack of environmental information on these compounds, worldwide. The main objective of this work was to characterize the levels of the most consumed progestins in Portugal. For that, Ria de Aveiro, Tagus estuary and Ria Formosa were sampled in a temporal perspective to evaluate levels of drospirenone (DRO), desogestrel (DSG), gestodene (GST) and levonorgestrel (LNG). Drospirenone and desogestrel were the most abundant progestins. In the North of Portugal, DSG was the most abundant (Aveiro: 193.9 ng L in summer), while DRO was more representative in the South (Tagus: 178.9 ng L; Formosa: 125.7 ng L) and also in summer. These spatial differences can be associated with the hydrodynamics of each estuarine system as well as the distinct population and tourist levels associated with each site.
合成孕激素是特别值得关注的微污染物，因为它们在人类和兽医治疗中的使用不断增加，并且对水生生物存在风险。目前，全世界都缺乏这些化合物的环境信息。这项工作的主要目的是表征葡萄牙最常用的孕激素的水平。为此，我们在时间范围内对阿威罗里亚、塔霍河口和福尔摩沙里亚进行了采样，以评估屈螺酮（DRO）、去氧孕烯（DSG）、孕二烯酮（GST）和左炔诺孕酮（LNG）的水平。屈螺酮和去氧孕烯是最丰富的孕激素。在葡萄牙北部，DSG 的含量最高（阿威罗：夏季 193.9ng/L），而 DRO 在南部更为普遍（塔霍：178.9ng/L；福尔摩沙：125.7ng/L），也是在夏季。这些空间差异可能与每个河口系统的水动力以及与每个地点相关的不同人口和旅游水平有关。
