Risk assessment of pesticides in the Netherlands is carried out using the computerised Uniform System for the Evaluation of Substances (USES). In USES the measure of risk is a single-point or deterministic estimate. Here, it is shown how a probabilistic assessment, incorporating knowledge about uncertainty and variability, can provide the decision-maker with improved insights into the risk management of pesticides. Advantages and possibilities of a probabilistic assessment are presented and provided with examples of calculations. This document is only intended for discussion; further efforts will be needed before a quantitative uncertainty analysis can be incorporated into the routine assessment of pesticides.
