![]() ![]() In outdoor dust, all concentrations of T- fipronil were less than 70?g/kg with one exception (430?g/kg). All three of the residences with a dog on which a flea-control product containing fipronil was used were among the five residences with elevated fipronil concentrations. Nineteen of 24 samples of indoor dust had T- fipronil concentrations less than 270 ?g/kg the remaining five had concentrations from 1320 to 14,200 ?g/kg. Fipronil accounted for most of the total fipronil (T- fipronil fipronil+desulfinyl fipronil+fipronil sulfide), followed by desulfinyl fipronil and fipronil sulfide. At least one of these three fipronil compounds was detected in every sample. ![]() We measured fipronil, fipronil sulfide, and desulfinyl fipronil concentrations in indoor and outdoor dust from 24 residences in Austin, Texas. Burkhardt, M.R.įipronil is a potent insecticide used for control of termites, fleas, roaches, ants, and other pests. (author) [ptįipronil and its degradates in indoor and outdoor dust The model is based on the point-kinetics approximation, with 2 delayed neutron percursors and up to 11 decay power generating groups. The program presents capabilities for on-line exchange of the operating parameters during the transient simulation, by friendly keyboard instructions. ![]() PC-REATOR, a reactor core transient simulation code has been developed for the real-time operator training on a IBM- PC microcomputer. ![]() International Nuclear Information System (INIS) PC-Reactor-core transient simulation code ![]()
