Flea foggers

This study was conducted to evaluate and compare ADD determined using whole-body dosimetry with results of two situational exposure studies conducted following use of a flea fogger under natural conditions. Chlorpy-rifos was selected due to its general availability as a fogger for indoor flea control. Chlorpyrifos is poorly absorbed by the dermal route and readily cleared from the body in urine (Nolan et al., 1984). Trichloropyridinol was measured in 24-hr urine specimens of the volunteers and was converted to chlorpyrifos equivalents as a measure of absorbed dose. The study provided an opportunity to determine the relationship between intensive, high-contact dosimetry studies and the amounts of chlorpyrifos absorbed by two sets of adults who re-entered fogger-treated homes. 

The foundation for this work was laid in 1989 when we adopted a low-impact Jazzercize routine of about 20 min to estimate daily exposure following the use of a flea fogger. The exercises were chosen to provide maximal surface contact between the subject and the pesticide-treated carpet (Ross et al., 1990). In the present case, two groups of volunteers performed the exercises concurrently one group wore cotton whole-body dosimeters... 

Multi-room foggers with a PBO synergized fen vale rate formulation, used twice at 10- to 14-day intervals, provides extensive c out nil of fleas and other flying and crawling insects In both home and industry uses. The actuator cap of this type of product allows the can to spray continuously until empty.
