Abstract
Abstract Selective determination of chlorinated hydrocarbons and alkylated benzenes in leachate of sanitary landfills and hazardous waste landfills was performed by headspace analysis. Identification was achieved by headspace GC MS analyses, quantitation by headspace GC, after spiking of the samples with all compounds in two concentrations (0.2 μg/250 μg). Within the hazardous waste landfills, the concentrations of chlorinated hydrocarbons ranged from 10 to 20000ppb, with methylene chloride, trichloroethylene and tetrachloroethylene as main constituents. They were detected only singularly up to 14ppb in the sanitary landfill samples. Benzene and alkylated benzenes were found in concentrations of 10 to 13000ppb in the leachates of the hazardous waste landfills and determined up to 500 ppb within the sanitary landfill leachates. The total contents of the chlorinated headspace compounds are discussed in terms of total organic chlorine with respect to the landfill type and to the corresponding AOX-values.
