Bibliography

This European Standard specifies a methodology for the determination of the leaching behaviour of a waste or a waste from the extractive industry under specified conditions (i.e. for a specified scenario including a specified time frame) in order to provide a solution to a defined problem. This applies to disposal and recovery scenarios.NOTE 1Recovery is the term defined in the European Waste Acts [1,3]. It includes re-use and recycling.The external conditions which have a direct influence on the release of constituents from waste are considered. Migration of constituents leached from the disposal or the recovery site into the surrounding environment is not considered. Also the assessment of toxicity to humans or ecological impacts on flora and fauna as a secondary effect after release of constituents from the waste is not considered.NOTE 2Present knowledge of highly complex scenarios and wastes may limit the ability to provide a clear solution to a defined problem. An example may be the land filling of complex mixtures of wastes or the prediction of the acid generation behaviour waste from the extractive industry.
