Malathion aerosol cloud behavior in a Coastal Plains pine flatwoods.

The study examines malathion aerosol cloud behavior in a North Florida pine flatwoods. Droplet mass median diameters (MMD) decreased over distance in both open and pine flatwoods. A sharp decrease in number of aerosol droplets per cm2 occurred between 3.1 and 15.2 m and a gradual decline in droplets per cm2 occurred beyond 15.2 m in both treatment areas. There were no interactions between habitat and distance in regard to MMD or droplets per cm2. Analysis of variance models accounted for 82% of the variability in the MMD data and 79% of the variability in the number of droplets per cm2.
