湖泊生态系统是环境变化的敏感记录器，提供了数千年来每年到十年分辨率的连续档案。对全新世湖泊沉积物中的土地利用变化和污染物排放进行系统调查，以及重建污染，背景条件和湖泊系统的敏感性，为研究环境动态和人类影响的后果提供了理想的机会，这些影响日益对人类福祉构成风险。本文讨论了沉积物和其他证据的使用，以提供湖泊生态系统的历史和当前污染的记录。我们提出了一种新的方法来调查人类活动的影响，使用化学分析，生物分析，生态，古湖泊，古生态毒理学，考古以及建模技术。这种多时间片证据权重方法将产生关于人类影响之前的条件的知识，并提供知识，以便（一）更好地了解人为干扰对生物多样性的影响，（二）通过使用关于历史污染和数千年来沉积物中污染物持久性的定量数据来评估水质，以及（iii）使用建模方法定义环境阈值。这一技术可用于深入了解具有长期土地使用和人类影响历史的集水区地表水和地下沃茨的参考条件，这仍然是一个主要需求，目前尚未在欧洲水框架指令范围内得到解决。
Lake ecosystems are sensitive recorders of environmental changes that provide continuous archives at annual to decadal resolution over thousands of years. The systematic investigation of land use changes and emission of pollutants archived in Holocene lake sediments as well as the reconstruction of contamination, background conditions, and sensitivity of lake systems offer an ideal opportunity to study environmental dynamics and consequences of anthropogenic impact that increasingly pose risks to human well-being. This paper discusses the use of sediment and other lines of evidence in providing a record of historical and current contamination in lake ecosystems. We present a novel approach to investigate impacts from human activities using chemical-analytical, bioanalytical, ecological, paleolimnological, paleoecotoxicological, archeological as well as modeling techniques. This multi-time slice weight-of-evidence (WOE) approach will generate knowledge on conditions prior to anthropogenic influence and provide knowledge to (i) create a better understanding of the effects of anthropogenic disturbances on biodiversity, (ii) assess water quality by using quantitative data on historical pollution and persistence of pollutants archived over thousands of years in sediments, and (iii) define environmental threshold values using modeling methods. This technique may be applied in order to gain insights into reference conditions of surface and ground waters in catchments with a long history of land use and human impact, which is still a major need that is currently not yet addressed within the context of the European Water Framework Directive.
