Field worker exposure estimation, discussion

All of the above factors must be considered while implementing the generic approach to estimating field worker exposure. An example how field data and several of the above factors are integrated into a generic estimate follow in the results and discussion. 

If field studies are conducted in which the variables are clearly delineated, it is possible that a model could be developed that would predict the maximum exposure under registered use conditions, and such a model would be of great value in the assessment of hazard to workers. This approach may be feasible for the orchard scenario because of the large number of studies that have been carried out. Some of the factors which should be taken into consideration in developing an exposure model and areas where there are insufficient data to make an accurate estimate will be discussed.
