  • Title: [Distribution pattern of chemicals in surface waters as a reflexion of entry pattern--description of the problems].
    Author: Heinisch E, Klein S.
    Journal: Z Gesamte Hyg; 1990 May; 36(5):234-7. PubMed ID: 2368451.
    Abstract:
    The distribution pattern of persistent substances made transparent chemically-analytically, in surface waters reflects--considering spatial-temporal limitations--an image of the input pattern. This permits in special cases repercussions on attributable (industrial enterprises, trade, plant production, pest control) or partly or completely anonymous (landfills, ancient deposits, contamination centres, traffic, atmospheric depositions) causative agents The classification of these information requires the knowledge of substance and substrate specifics, especially detailed information about production and/or application of the substances and so represents an interdisciplinary task. Assessing single substance analyses permits a comparison with limit values or literature data. The consideration of combinations of substances which belong together due to production, application and/or transformation may help to elucidate the input patterns. This differential-diagnostic method is presented by a first evaluation of analytical findings in surface waters of an industrialized town and its surroundings.
