Polluted industrial soils are causing considerable difficulties in industrialized countries. Reclamation of polluted areas requires considerable expenditure as well as the disposal or destruction of the waste. In view of the problem of elimination of dangerous waste several Directives have already been adopted (e.g. 78/319/EEC, 75/442/EEC or 87/216/EEC) which deal with removal, treatment and transport of waste. Other Directives in this field are expected in the near future.
The accurate characterization of waste has considerable economic consequences because the results of these are used to decide on the treatment to be applied for reclamation. Organo-chlorine compounds are within the most commonly encountered type of contaminants. Over the last decades large areas have been exposed, by industrial activities, to contamination by chlorobenzenes (CBs), chlorophenols (CPs), polychlorodibenzo-p-dioxins and furanes (PCDDs and PCDFs), chorinated pesticides, polychloro-biphenyls (PCBs) and the side products.
This project intends to study the various analytical steps of the determination of CPs, CBs, PCDDs and PCDFs in order to highlight the sources of errors of the analytical methods. Finally two soils should be certified for CPs - CBs and dioxins when the methods applied by the participating laboratories have reached a sufficient reliability.
A certified reference material is in preparation.
