The certification of trace elements in waste materialsFunded under: FP2-BCR 4
Human activities produce increasing amounts of waste. In the past, materials such as sewage sludge and harbour dredge were used for landfill purposes, while incineration ash and dust were used as fillers for concrete and in road construction. Nowadays, their elimination has become a problem because of their quantity and their possible toxicity. Precautions have to be taken in removal, treatment and transport of wastes. Analyses are required to establish their toxicity and to treat them properly. In order to improve the quality of the determination of trace and toxic elements in waste materials, the Community Bureau of Reference (BCR) has produced various certified reference materials (CRMs): City waste incineration ash (CRM 176); Fly ash from the combustion of pulverised coal (CRM 38); sewage sludge of domestic origin (CRM 144); sewage sludge of mixed origin (CRM 145); Sewage sludge of industrial origin (CRM 146). All CRMs followed the same certification procedure developed by the BCR. The main results are presented. Additional CRMs have also been produced such as PCBs in sewage sludge (CRM 392).
