Field Study Methods for the Determination of Bystander Exposure to Pesticides

Techniques to estimate bystander exposure are described. Passive sample media such as filter paper are used to collect spray drift. Air-sampling devices are used to determine the airborne concentration of pesticides. The use of a mannequin or volunteer dressed in a disposable coverall standing downwind of the treated zone gives the most accurate indication of the potential dermal exposure of a bystander.
