MAMMALIAN TOXICOLOGY
Acute toxicity: 1) Acute oral LD50 for rat: >16.2 a.i.mg/kg. 2) Acute dermal LD50 for rat: >5000 a.i.mg/kg. 3) Inhalation LC50 (4 h) for rat: 4.05 a.i. mg/L. 4) Non- irritating to skin (rabbits). 5) Slightly- irritating to eyes (rabbits). 6) Not a skin sensitiser (guinea pigs). There was no evidence of carcinogenicity, genotoxic, or teratogenicity; A three generation reproductive study in rats produced a systemic No Observable Effect Level (NOEL) of 50 ppm (2 mg/kg/day), and a Low Observable Effect Level (LOEL) of 150 ppm (7.5 mg/kg/day) based on decreased body weights in pups. It was also determined that the NOEL and LOEL for viability of offspring were 50 ppm and 150 ppm, respectively.
ADI (JMPR): 0.004 mg/kg b.w.[2006]
Classification:
Toxicity class WHO (a.i.): Ib (Highly hazardous)
US EPA Classification (formulation): II (Warning - Moderately toxic)
EC Risk Classification:T+ - Very toxic: R26/28; N - Dangerous for the environment: R50, R53

ENVIRONMENTAL FATE
Cyfluthrin's production may result in its release to the environment through various waste streams; its use as an insecticide will result in its direct release to the environment. If released to air, a vapor pressure of 1.510-10 mm Hg at 20 deg C indicates cyfluthrin will exist solely in the particulate phase in the atmosphere. Particulate-phase cyfluthrin will be removed from the atmosphere by wet or dry deposition. If released to soil, cyfluthrin is expected to have slight to no mobility based an experimental Koc range of 3,700 to 33,913. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.910-8 atm-cu m/mole. Aerobic biodegradation half-lives of 56-63 days, 7-90 days, and 116 days suggest that biodegradation is a slow environmental process in soil. The initial products of cyfluthrin anaerobic biodegradation in soil are 3-(2,2-dichlorovinyl)2,2-dimethylcyclopropancarboxcylic acid and 4-fluoro-3-phenoxybenzoic acid with a degradation rate of 90% over 140 days. If released into water, cyfluthrin is expected to adsorb to suspended solids and sediment based upon the Koc range. Photolysis is expected to be an important environmental fate process for cyfluthrin in water. An experimental half-life of 16 hours was measured for cyfluthrin in aqueous solution when irradiated with light at wavelengths of >290 nm. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 170 suggests the potential for bioconcentration in aquatic organisms is high. The four diastereoisomeric pairs that compose cyfluthrin undergo hydrolysis in water with half-lives ranging from 25-117 days at pH 4, 11-20 days at pH 7, and 3-7 days at pH 9, all at 22 deg C. Occupational exposure to cyfluthrin may occur through dermal contact with this compound at workplaces where cyfluthrin is produced or used. Monitoring data indicate that the general population may be exposed to cyfluthrin via ingestion of food, and dermal contact with this compound.
Usage: Cyfluthrin is developed by bayer, Germany. Cyfluthrin is a non-systemic Insecticide with contact and stomach action. Acts on the nervous system, with rapid knockdown and long residual activity.
Application: Cyfluthrin is an Insecticide effective against many pests, especially Lepidoptera, Coleoptera, Homoptera and Hemiptera on cereals, cotton, fruit and vegetables; also against migratory locusts and grasshoppers. For agricultural uses, Cyfluthrin is applied at 15-40 g/ha. Cyfluthrin is used against Blattellidae, Culicidae and Muscidae in public health situations, stored products, domestic use and animal health. Cyfluthrin has a rapid knockdown effect and long-lasting residual activity.
