  1. Pesticide inhalation exposure, air concentration, and droplet size spectra from greenhouse fogging.

    Article - En anglais

    Fogger application of pesticide in greenhouses can reduce application time and applicator contact with equipment.

    Since fog applications use smaller and more concentrated droplets than typical wet spray applications, potential for inhalation and off-target transport hazards may be increased.

    This study investigated temporal characteristics of airborne pesticide after thermal fogging of a greenhouse.

    Droplet size spectra and concentration of airborne pesticide were measured.

    Volume median diameter of the suspended aerosol decreased from 14 to 2.3 mum during 1.5 h after application.

    Concentration of airborne pesticide decreased by 60% in the first hour after application and by 95% during 12 h after application.

    Implications for respiratory exposure were analytically developed from observed data.
