| Abstract: | The importance of systematic trends in trace contaminant leaching from waste materials and stabilized waste is stressed. Similarities in leaching behaviour of different waste materials and mechanisms for leaching from stabilized waste forms are identified. The use of diffusion measurements to quantify the mobility of specific chemical species in waste and soil is discussed. Implementation of more fundamental regulatory testing procedures which reflect the behaviour of materials in end use applications, is recommended to allow better control over environmental impact in the wide variety of utilization and disposal practices. |
