Project

Division of Chemistry and the Environment (VI)

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).

This project was presented at a poster session at the IUPAC Congress/GA July 2001
