Acute toxicity: 1) Acute oral LD50 for rat: 92 a.i.mg/kg. 2) Acute dermal LD50 for rat: 354 a.i.mg/kg. 3) Inhalation LC50 (4 h) for rat: 0.36 a.i. mg/L. 4) Slightly - irritating to skin (rabbits). 5) Mildly- irritating to eyes (rabbits). 6) Not a skin sensitiser (guinea pigs). No indications of a developmental toxicity or teratogenic effects were seen in animal studies. Signs of toxicity during a 52-week chronic rat feeding study included reduced feeding and food conversion efficiency, reduced body weight gain, seizures and seizure-related death, changes in thyroid hormones, increased mass of the liver and thyroid, and kidney effects. The EPA has classified fipronil a Group C Possible Human Carcinogen based on laboratory animal studies (increased thyroid tumors in male and female rats). Results from a number of mutagenicity studies, there is no indication that the substance is mutagenic. A neurotoxic in both rats and dogs as shown in the acute and sub-chronic screening in the rat.

Fipronil'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 2.78×10-9 mm Hg at 25 deg C indicates fipronil will exist solely in the particulate phase in the atmosphere. Particulate-phase fipronil will be removed from the atmosphere by wet or dry deposition. Fipronil contains chromophores that absorb at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, fipronil is expected to have low to no mobility based upon Koc values of 825 to 6863. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 8.4×10-10 atm-cu m/mole. Photolytic half-lives in soil for fipronil were reported as 147 to 217 hours. Fipronil is expected to biodegrade in soil and water based upon studies showing estimated degradation half-lives of 25.1 to 91.2 days in three sediments under aerobic conditions and 4.6 to 18.5 days for the same sediments under anaerobic conditions. If released into water, fipronil is expected to adsorb to suspended solids and sediment based upon the Koc values. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. A whole body BCF of 321 in bluegill suggests bioconcentration in aquatic organisms is high. Fipronil is stable to hydrolysis at pH 5.5 and pH 7, but has a hydrolysis half-life of 28 days at pH 9. An aqueous photolytic half-life for fipronil was reported as 4.1 hours. Occupational exposure to fipronil may occur through inhalation of dust and dermal contact with this compound at workplaces where fipronil is produced or used. Monitoring data indicate that the general population may be exposed to fipronil via inhalation of dust and dermal contact with this compound or other products containing fipronil.

Usage: Fipronil was discovered and developed by Rhône-Poulenc between 1985 and 1987, and placed on the market in 1993 under the B2 U.S. Patent 5,232,940 B2. Between 1987 and 1996, fipronil was evaluated on more than 250 insect pests on 60 crops worldwide, and crop protection accounted for about 39% of total fipronil production in 1997. Since 2003, BASF holds the patent rights for producing and selling fipronil-based products in many countries.

Application: Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole chemical family. Fipronil disrupts the insect central nervous system by blocking GABA-gated chloride channels and glutamate-gated chloride (GluCl) channels. This causes hyperexcitation of contaminated insects' nerves and muscles. Fipronil's specificity towards insects is believed to be due to its greater affinity to the GABA receptor in insects relative to mammals and its effect on GluCl channels, which do not exist in mammals. Fipronil is used for controlling of multiple species of thrips on a broad range of crops by foliar, soil or seed treatment. Control of corn rootworm, wireworms and termites by soil treatment in maize. Control of boll weevil and plant bugs on cotton, diamond back moth on crucifers. Foliar application rates range from 10-80 g/ha; soil treatment rates 100-200 g/ha.
