WebTherefore, cyfluthrin is 42% active isomers when compared to beta-cyfluthrin (41/97 = 42). Therefore, the assumption is that the toxicity endpoints for beta-cyfluthrin should be 42% of the cyfluthrin endpoints (e.g., if the cyfluthrin endpoint is 1 mg a.i./L, than the estimated beta-cyfluthrin endpoint would be 0.42 mg a.i./L). WebThe developmental NOAEL is 10mg/kg/day. This developmental study in rats was classified core guideline. ii. Oral developmental study in rabbits. Cyfluthrin was administered via gavage to pregnant female rabbits during days 6-18 of gestation at dose levels of 0, 20, 60, or 180 mg/kg/day.

The resulting NOAEL was 1.4 mg/ m3, based on treatment-related behavioral … Cyfluthrin and beta-cyfluthrin are two active substances differing only in their isomeric composition. While cyfluthrin consists of four enantiomeric pairs of diastereoisomers, beta-cyfluthrin represents the biologically more active diastereoisomers (isomers II and isomers IV). simon wall sanktnovius bjurfors
