Dry Deposition and Spray Drift of Pesticides to Nearby Water Bodies

Abstract
During field application of pesticides, some of it will reach adjacent water bodies through atmospheric dry deposition and spray drift A model was developed to calculate the volatilisation, atmospheric transport and dry deposition of pesticides to water bodies (streams, ditches and lakes) caused by application on nearby fields. It appears that the contribution of dry deposition of those pesticides, that are highly volatile as well as highly soluble, to water bodies is of the same order or even larger than the contribution from spray drift. Spray drift is only important over a relatively short distance (less than 30 m) from the edge of a field, whereas dry deposition can also be important further away. The model, that includes a description of spray drift, is built in into an integrated model used for estimating the risk of transport of pesticides to water bodies. This integrated model describes not only the atmospheric contribution to water bodies, but also the contribution via other pathways.

The Danish Environmental Protection Agency will, when opportunity offers, publish reports and contributions relating to environmental research and development projects financed via the Danish EPA.

Please note that publication does not signify that the contents of the reports necessarily reflect the views of the Danish EPA.

The reports are, however, published because the Danish EPA finds that the studies represent a valuable contribution to the debate on environmental policy in Denmark.
