Systematic Leaching Behaviour of Trace Elements from Construction Materials and Waste Materials.

Summary This paper focuses on systematic trends observed in the characterization of contaminant leaching from solid wastes including stabilized wastes, sintered and cement-based products containing waste materials. The improved experimental methods available to evaluate these products are briefly reviewed. The interpretation of test results in terms of systematic trends is shown to be essential for judging the environmental acceptability of waste disposal or utilization activities.
