Five jet software have been made, a couple ranging from 0800 and you can 0830 hours for the 4 and you will eleven December, as well as 2 in early evening between 1730 and you may 1800 hours into six and you can thirteen December 1990. Apps corresponded everything for the program returning to SNEM spray operations into the Panama Area. Droplet dimensions since frequency median diameter (VmD) are sampled immediately prior to apps making use of the fall wave techniques demonstrated of the Beidler (1975) and you will averaged 19.eight, 17.5, 14.step one, and you will 16.8 ?m getting 4, six, 11, and you will bient air temperature was registered at the start of each application.

(1986). For every filter out paper is actually listed in a synthetic handbag, returned to the brand new laboratory and the insecticide removed and you can quantified playing with another gasoline chromatographic actions.
