Reduction of drift in spray application/ nebulization of biocides - Derivation of risk reduction measures and device requirements

The choice of the equipment for the application of biocides can have a big influence on the drift potential and thus on the emission of biocides into the environment. This is especially true for spray applications. The goal of the study was to evaluate the drift potential to

1. discuss possible regulations or recommendations on the equipment for the application of biocides.
2. derive exposure values for the exposure assessment of biocides.

The results show that drift is likely for the studied applications. This might lead to risks for non-target organisms. However, drift might be minimized by using drift-reducing equipment. These possibilities will be further evaluated in a follow-up project.
