COMMISSION ON AGROCHEMICALS AND THE ENVIRONMENT (VI.4)
Number: 640/43/97
Title: Pesticide Soil Sorption Parameters Kd and Koc: Theory,
Measurement, Use, Limitations and Reliability
Coordinator(s): D.
Wauchope
Remarks: Proposed as cooperative project with Commission on
Fundamental Environmental Chemistry (VI.1)
Completion Date: 2001 - project completed
Objective:
Objective is to critically analyze information on the variability of
Kd and Koc and recommend rules for estimating the probable errors and
limitations of these parameters when used to predict pesticide mobility
and movement to water sources. Project will facilitate increased accuracy
of environmental exposure assessments targeted at surface and groundwater,
and is needed by regulatory agencies and pesticide manufacturers.
Progress:
Outline draft available; full draft to be prepared by April, 1999. Near
final report and project conclusions and recommendations will be available
for review by the Commission on Agrochemicals and the Environment at
the Berlin General Assembly during August, 1999. Final draft report
being circulated for review; recommendations approved by the Commission
(June 2000).
The final report has been published: Wauchope RD, Yeh S, Linders JBHJ,
Kloskowski R, Tanaka K, Rubin B, Katayama A, Kördel W, Gerstl Z,
