Worker exposure studies and risk assessments have routinely been performed based on the assumption that the physical parameters of handling, application, and reentry activities, not the chemical properties of the pesticide, are most important in determining the level of exposure.  While reasonable, the number of variables involved in worker exposure studies has made validating this basic assumption difficult.  Bayer Crop Science has performed a study that allowed for the testing of this assumption through the simultaneous monitoring of multiple active ingredients during handling activities.  An analysis of the results of that study, focused on the relationship between dermal and inhalation exposure based on amount of material handled, will be presented.

Are the assumption of genericness and the use of surrogate chemicals in worker exposure and risk assessment valid?
