Synthetic polymers as environmental contaminants received a very high attention in the past years. The scientific efforts focused so far dominantly on the occurrence of macro- and microplastic particles in the aquatic environment. However, water soluble or dissolved polymers have been neglected so far, although they are produced, used and consequently discharged in high quantities. Additionally, they are known to be stable under environmental conditions and, consequently, an emission towards surface water systems by sewage effluents has to be assumed.Analytical approaches currently developed for plastics are transferable only to a very low extent to water-soluble polymers. Hence, this project will focus on the development of an appropriate analytical approach based on pyrolysis methods for quantifying dissolved polymers in sewage and surface water. The chemical properties of dissolved synthetic polymers as well as the low environmental concentration levels are hereby the main challenges. In a second part of the project, influents and effluents of representative waste water treatment plants as well as samples from receiving river systems will be analyzed quantitatively by applying the developed analytical procedure. The obtained results will be a first glance on the overall discharge of water-soluble polymers into river systems, i.e. an estimation of the pollution dimension.

在过去几年中，作为环境污染物作为环境污染物的合成聚合物受到了极大的关注。迄今为止，科学努力主要集中在水生环境中宏观和微塑料颗粒的发生上。但是，到目前为止，迄今已忽略了水溶性或溶解的聚合物，尽管它们被产生，使用并因此被大量排放。此外，已知它们在环境条件下是稳定的，因此，必须假定污水处理对地表水系统的发射。目前针对塑料开发的分析方法只能在非常低的程度上转移到水溶性聚合物中。因此，该项目将基于用于量化污水和地表水中溶解聚合物的热解方法的适当分析方法的开发。溶解的合成聚合物的化学特性以及低环境浓度水平是主要挑战。在该项目的第二部分中，代表性废水处理厂的进水和废水以及接收河流系统的样本将通过应用开发的分析程序进行定量分析。获得的结果将是水溶性聚合物整体排放到河流系统中的乍一看，即对污染尺寸的估计。
