Abstract：
In temperate coastal areas, the resident population often increases during holidays. As a result, this can lead to higher wastewater production and release of pollutants. The connection between micropollutants such as plasticizers and hormones with the changing resident population along the Baltic Sea coast has yet to be thoroughly studied. Therefore, we have monitored the wastewater quality and specific micropollutants before and after treatment at wastewater treatment plants (WWTPs) at small and large seaside resorts. The findings indicate a strong link between tourism indicators and wastewater production during the summer months. The rise in different micropollutants, specifically plasticizers, during the summer demonstrates a link with tourism activity. Furthermore, we have identified a non-linear association between the tourism indicators and the total estrogenic equivalent (EEQ). Overall, this research particularly emphasizes the growing importance of wastewater quality in terms of conventional nutrient pollution and various micropollutants.
摘要：
在温带沿海地区，常住人口经常在假期增加。因此,这可能导致更高的废水产量和污染物的释放。诸如增塑剂和激素之类的微污染物与波罗的海沿岸不断变化的常住人口之间的联系尚未得到彻底研究。因此,我们在小型和大型海滨度假胜地的污水处理厂（WWTP）处理前后监测了废水质量和特定的微污染物。调查结果表明，夏季旅游指标与废水产生之间存在紧密联系。不同微污染物的增加，特别是增塑剂，在夏季展示了与旅游活动的联系。此外，我们已经确定了旅游指标与总雌激素当量（EEQ）之间的非线性关联。总的来说,这项研究特别强调了废水质量在常规营养污染和各种微污染物方面的重要性。
