DETERMINATION OF PCDD F FOR HAZARD ASSESSMENT IN A MUNICIPAL LANDFILLCONTAMINATED WITH INDUSTRIAL SEWAGE-SLUDGE/

Because of former depositions of dioxin-containing industrial sewage s ludges in a municipal landfill (1983-93), investigations on the possib le hazards from polychlorinated dibenzo-p-dioxins and -furans (PCDD/F) during regular operations on site became necessary within the scope o f an preliminary acute assessment of the environmental health situatio n. To achieve this, samples of different compartments (air, soil, sedi ment) were taken to determine wether an increased residual pollution w ith PCDD/F is discernible. The analytical results do not indicate any hazard for the staff or the environment on the air path, that is by wi nd erosion or volatilization, if no excavation work is carried out. Fo r recultivation activities on the polluted old landfill site, however, working precautions are recommended to exclude possible risks for the workers. Informations about contamination of ground water are to be g athered. For this, drill cores through the body of the old landfill wi ll be analyzed in the near future.
