Horizontal Standardization and Harmonization of Leaching Test Methods for Waste, Secondary Raw Materials, Construction Materials and (contaminated) Soil
In recent years, a lot of work has been carried out in evaluating environmental impact from a wide variety of materials in a wide range of different applications. The continously recurring inability to compare results between different jurisdictions and between disciplines can be resolved by focusing on a limited number of key test methods. This does require the recognition that many existing t...
متن کاملAn Integrated Framework for Evaluating Leaching in Waste Management and Utilization of Secondary Materials
A framework for the evaluation of inorganic constituent leaching from wastes and secondary materials is presented. The framework is based on the measurement of intrinsic leaching properties of the material in conjunction with mathematical modeling to estimate release under field management scenarios. Site specific and default scenarios are considered, which may be selected based on the evaluati...
متن کاملLeaching behaviour of elements and evaluation of pre-treatment methods for municipal solid waste incinerator residues in column leaching tests.
Two new pre-treatment methods (water-washing/carbonation and carbonation/phosphate stabilization) of municipal solid waste (MSW) incinerator residues were evaluated by column leaching tests under aerobic conditions and anaerobic conditions (which were changed to aerobic conditions after 10 months). A mixture of bottom ash and fly ash (5:1 ratio) was pre-treated using each method. Shredded incom...
متن کاملPesticides and toxic chemicals
‘Contamination’ is a comparative term. In Britain at least, contaminants are trace substances; in the context of food they are distinguished from additives by whether or not there is an intention that the substances should be present when the food is consumed or prepared for consumption. Contaminants may be of natural or of technological origin: and technological contaminants may be direct or i...
