    Abstract - (Show below) - (Hide below)

    Gives a methodology used to determine the leaching behaviour of a waste under specified conditions (i.e. for a specified scenario that includes a specified time frame) so as to provide a solution to a specific problem. Applicable to disposal and utilization scenarios.
