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).
