| Abstract: | Extensive investigations of leachates and solid waste samples for organic sum parameters and environmentally relevant organic compounds were carried out at the hazardous waste landfill of Raindorf, which is operated in accordance with German Technical Instructions on Waste (TI Waste). The measurements showed that the majority of the waste samples contained only minor amounts of phenols, highly volatile chlorinated organic compounds (VCHC), benzene, toluene, ethylbenzene and xylene (BTEX), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH). The concentrations ranged from less than 100μg/kg?1up to 1000μg/kg?1of dry substance. Only hydrocarbons were detected in higher concentrations (mg to g kg?1of dry substance). In most leachate and gas samples taken at the landfill, the concentrations of the abovementioned parameters were close to or even below the detection limit. The measurement of organic single compounds underlined the usefulness of the sum parameters, adsorbable organic halogen compounds and phenol index, for the estimation of the total amount of these substances. A comparison of organic sum parameter concentrations measured in leachates from landfills of differing ages indicates that the application of TI Waste leads to a reduction of the organic load in the leachate. |
