Project Details Pesticide Soil Sorption Parameters Kd and Koc: Theory, Measurement, Use, Limitations and Reliability

Project No.:
Start Date:
01 January 1997
End Date:
31 December 2001


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.


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,Lane M and Unsworth JB. 2002. Pesticide soil sorption parameters: theory,measurement, uses, limitations and reliability. PestManagement Science58:419-445.
