Ryan*, J A. AND W. R. Berti. FIELD EVALUATION OF THE IN-SITU TREATMENTS TO REDUCE SOIL LEAD BIOAVAILABILITY: CONCLUSIONS. Presented at ASA-CSSA-SSS Annual Meeting, Charlotte, NC, 10/22-25/2001.
Description:
This presentation summarizes the conclusion of the technical issues associated with the Pb bioavailability experiment which IINERT has been conducting and further to illustrate that although bioavailability is a simple concept, its measurement and the implementation of the measurement in a regulatory framework is complex. Illustrating that mineralogical changes in soil can be accomplished by additions of material to the system can be a complex technical task requiring expertise in geology, chemistry and soil science. To demonstrate these mineralogical changes alter bioavailability requires additional expertise from nutritionists, veterinarians and toxicologists. To integrate the understanding obtained by these technical efforts into a regulatory framework adds another dimension in complexity requiring inputs from legal and regulatory authority. This challenge must be addressed by the technical community as it strives to provide advances of understanding into acceptance and use by society.
