Mol. wt.: 419.9; M.f.: C25H22ClNO3; Form: Tech. fenvalerate is a viscous yellow or brown liquid, sometimes partly crystalline at room temperature. M.p.: 39.5-53.7 °C (pure). B.p.: Decomposes on distillation. V.p.: 1.92x10-2 mPa (20 ºC). KOW: logP = 5.01 (23 ºC). S.g./density: 1.175 (25 ºC). Solubility: In water 5000 mg/kg. Slightly irritating to skin and eyes (rabbits). Inhalation: LC50 for rats >101 mg/m3. NOEL: (2 y) for rats 250 mg/kg diet. ADI: 0.02 mg/kg b.w. Toxicity class: WHO (a.i.) II; EPA (formulation) II ECOTOXICOLOGY Birds: Acute oral LD50 for domestic fowl >1600, mallard ducks 9932 mg/kg. Dietary LC50 for quail >10 000, mallard ducks 5500 mg/kg. Fish: LC50 (96 h) for rainbow trout 0.0036 mg/l. Bees: Toxic to bees. Contact LD50 0.23 ug/bee. ENVIRONMENTAL FATE Animals: In mammals, following oral administration, fenvalerate is rapidly metabolised. Up to 96% is excreted in the faeces within 6-14 days. For a study of the metabolism of fenvalerate in the laying hen. Plants: In plants, fenvalerate is split into two parts by cleavage of the ether group, followed by further hydroxylation in the 2- and 4- positions of the phenoxy ring, and hydrolysis of the nitrile group to amide and carboxyl groups. The majority of the acids and phenols thus formed are converted into glucosides. Soil/Environment: In aqueous media, the ester bond is hydrolysed. In light, decarboxylation occurs, with recombination of the cleaved moieties. DT50 in soil c. 75-80 d.
