Supplemental Hazard Statements: none


Acute toxicity: 1) Acute oral LD50 for rat: 12 a.i.mg/kg. 2) Acute dermal LD50 for rat: 31 a.i.mg/kg. 3) Inhalation LC50(4 h) for rat: 0.05 a.i. mg/L. 4) Non- irritating to skin (rabbits). 5) Severely- irritating to eyes (rabbits). 6) Not a skin sensitiser (guinea pigs). Exposure to Chlorfenvinphos causes the classic anticholinesterase symptoms-inhibition of acetylcholinesterase activity results in accumulation of acetylcholine at muscarinic and nicotinic receptors leading to peripheral and central nervous system effects. These effects usually appear within a few minutes to a few hours after exposure depending on the extent of exposure. No studies were located regarding the following health effects in humans or animals after acute-, intermediate-, or chronic-duration inhalation exposure to Chlorfenvinphos: Reproductive Effects, Developmental Effects, Genotoxic Effects, Cancer. There is no data to hand indicating any particular target organs.

Chlorofenvinphos was used as an insecticide, acaricide, and parasiticide resulted in its direct release to the environment. If released to air, a vapor pressure of 7.5×10-6 mm Hg at 25 deg C indicates chlorofenvinphos will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase chlorofenvinphos will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone; the half-lives for these reactions in air are estimated to be 7 and 92 hours, respectively. Particulate-phase chlorofenvinphos will be removed from the atmosphere by wet and dry deposition. Based on persistence studies in river water, chlorofenvinphos may have the potential for direct or indirect photolysis in the environment. If released to soil, chlorofenvinphos is expected to have moderate mobility based upon a Koc of 295. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.9×10-8 atm-cu m/mole. The persistence half-lives for chlorofenvinphos ranged from about 14 days to >150 days in soil. The initial half-live of chlorofenvinphos in soils varied from 2 wks to more than 23 wks depending on the soil type, the formulation, and the dosage level. If released into water, chlorofenvinphos is expected to adsorb to suspended solids and sediment based upon its Koc. The persistence half-life of chlorofenvinphos in river water limited to only chemical and biodegradation was 51.2 days; whereas samples in which chlorofenvinphos disappeared by volatilization, adsorption as well as chemical and biological degradation, had a half-life of 13.2 days. 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 28 suggests bioconcentration in aquatic organisms is low. Chlorofenvinphos hydrolyzes slowly in neutral, acidic and slightly alkaline solution. Hydrolysis half-lives for chlorofenvinphos were >700 hrs at pH 1.1 and >400 hrs at pH 9.1 (at 38 deg C). Occupational exposure to chlorofenvinphos may occur through inhalation and dermal contact with this compound at workplaces where chlorofenvinphos is produced or used. Occupational exposure to chlorofenvinphos was reported to occur in workers in CA who handle flea control products. Monitoring data indicate that the general population was infrequently exposed to chlorofenvinphos via ingestion of food containing chlorofenvinphos residues.

Usage: Dermaton is developed by Shell International Chemical Company Ltol. It was introduced in the United States in 1963 and was used as an insecticide and acaricide for controlling fleas and ticks on domestic pets and other animals. Between 1963 and 1970, additional uses were registered, including the use as fly spray, surface spray and larvicide. Because of these effects, chlorfenvinphos was often used on farms to control adult flies in dairy barns, milk rooms, poultry houses and yards and other animal buildings. Furthermore, it was used to control larval flies in manure storage pits and piles and other refuse accumulation areas around dairies and feedlots. In the early 1980s, chlorfenvinphos was registered for additional uses in a dust formulation for use in dog kennels and in dog collars for the control of fleas and ticks.

Application: Used to control insect pests on livestock,controls ticks and kills lice. control household pests such as flies, fleas, and mites.It also can be used as preharvest insecticide for various rootflies in root-vegetables and soil insecticide for root maggots, rootworms, cutworms; foliage insecticide for potato beetle, citrus scale, rice stem borers, cotton whitefly; seed dressing for wheat bulb fly.
