  • Title: [Distribution pattern of chemicals in surface waters as a reflexion of entry pattern--volatile halogenated hydrocarbons].
    Author: Klein S, Heinisch E, Stottmeister E, Hendel P, Hermenau H.
    Journal: Z Gesamte Hyg; 1990 May; 36(5):241-4. PubMed ID: 2368452.
    Abstract:
    The part gives some data about various light volatile halogenated hydrocarbons in surface waters of the industrialized city and its surroundings--the halogenated forms, chloroform and bromoform and the most used solvents trichloroethylene, tetrachloroethylene, tetrachloromethane and 1,1,2,2-tetrachloroethane. 80% of the concentrations of chloroform, tri- and tetrachloroethylene were in the range of less than 1 microgram l-1, 90% of bromoform, tetrachloromethane and 1,1,2,2-tetrachloroethane were found to amount less than 0.1 microgram l-1. With the help of the differential-diagnostic assessment method described in the first part we tried to evaluate the data for tetrachloromethane. The highest values were obtained for almost all sampling points in April--a possible cause may be the use of this solvent for cleaning and repairing procedures with sport boats (although tetrachloromethane has been prohibited for such uses for some years there may be some remainders which were used for these purposes).
