Various past or recent industrial activities have caused, amongst others, that materials such as sewage sludge, harbour dredge, which in the past were used for landfill purposes or for improvement of the soil structure, have now become dangerous 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 precautions to be taken for removal, treatment and transport of wastes.
The European Round Table held in November 1985 suggested that studies be undertaken on the impact of waste disposal and treatment facilities, and of abandoned contaminated industrial sites.
Problems related to hazardous waste are now being considered as of primary concern to DG XI.
This project will be devoted to the characterization of the risk on disposal of harbour dredge. Several inorganic (e.g. As, Pb, Hg, Cd, Cr, etc) and organic (PCBs, PAH, OCPs, dioxins, etc) toxic parameters will be certified.
A certified reference material is in preparation.
