Field sampling, airborne pesticides

The intent of this article is to provide an overview of methodology and materials for sampling airborne pesticide spray and spray collection on surfaces by sedimentation deposition and impaction after release from field sprayers. The term pesticide will be used as a general term to represent chemicals such as herbicides, insecticides, fungicides and related products. 

Some aspects of the sources, occurrence, and dispersion of airborne pesticide residues (6, 27) and methods for their sampling and analysis (28, 29, 30, 31) have been reviewed elsewhere. In this paper, the focus will be on sampling methodology, experimental design, and some results from recent field tests aimed at determining the entry and proximate fate of airborne residues in relation to specific agricultural treatments.
