title: The anthropogenic contribution to the organic load of the Lippe River (Germany). Part II: Quantification of specific organic contaminants.
abstract: 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.
