The major goal of this study was to investigate the organic pollution of a river on a quantitative basis. To this end, 14 anthropogenic contaminants which were identified in Lippe River water samples as reported in part I (Dsikowitzky et al., submitted parallel to this manuscript) were surveyed. Dissolved organic loads of the specific compounds were calculated on the basis of their concentrations in water and river runoff on the day of sampling. The organic loads of each compound were compiled along the longitudinal section of the river in order to generate individual spatial pollution profiles. It was observed that distribution of organic loads along the river showed distinctive patterns, depending upon the input situation and physico-chemical properties of the compound. The compounds were classified into three types of which Type 1, due to their stability in the aqueous phase, are of special interest for potential application as anthropogenic markers.
本研究的主要目标是对一条河流的有机污染进行定量调查。为此，对利珀河河水样本中鉴定出的14种人为污染物进行了调查，如第一部分（Dsikowitzky等人，与本手稿同时提交）所报道。特定化合物的溶解有机负荷是根据采样当天其在水中的浓度和河流径流量计算得出的。为了生成各个空间污染剖面图，沿着河流的纵向剖面汇编了每种化合物的有机负荷。据观察，河流沿线有机负荷的分布呈现出独特的模式，这取决于化合物的输入情况和物理化学性质。这些化合物被分为三种类型，其中第1类由于其在水相中的稳定性，作为人为标志物具有潜在应用价值，因而备受关注。
