EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting. Thus, the risk of increasing the medical problems by inducing vomiting of a volatile corrosive chemical is very high. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

General First Aid:

· Call 911 or emergency medical service.

· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.

· Move victim to fresh air if it can be done safely.

· Administer oxygen if breathing is difficult.

· If victim is not breathing:

-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.

-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).

-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.

· Remove and isolate contaminated clothing and shoes.

Benzotrifluoride's production and use in dye chemistry, high polymer chemistry, as a solvent, dielectric fluid, vulcanizing agent, insecticide, and as an intermediate for pharmaceuticals, may result in its release to the environment through various waste streams. It has been detected in river water, sediments, and in industrial effluent discharge. If released to soil, benzotrifluoride will have low mobility. Volatilization of benzotrifluoride may be important from moist and dry soil surfaces. Benzotrifluoride will not be susceptible to direct photolysis on soil or water surfaces based upon its lack of absorption of light at wavelengths >290 nm. Biodegradation of benzotriflouride will not be an important fate process in soil or water according to a biodegradation study. If released to water, benzotrifluoride may adsorb to suspended solids and sediment. Benzotrifluoride may volatilize from water surfaces with estimated half-lives for a model river and model lake of about 3.6 hours and 4.8 days, respectively. Experimental BCF values of 26-54 and 31-58 suggest that benzotrifluoride will bioconcentrate in aquatic organisms. If released to the atmosphere, benzotrifluoride will exist in the vapor phase. Vapor-phase benzotrifluoride is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals with an estimated half-life of about 35 days. Vapor-phase benzotrifluoride is also degraded in the atmosphere by reaction with ozone with an estimated half-life of about 6.3 years. Particulate-phase benzotrifluoride may be physically removed from the air by wet and dry deposition. (SRC)

Volatilization of benzotrifluoride may be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 0.017 atm-cu m/mole(SRC), calculated from experimental values of vapor pressure(4) and water solubility(5), and from dry soil surfaces(SRC) based on an experimental vapor pressure of 38.83 mm Hg(4). Benzotrifluoride will not be susceptible to direct photolysis on soil surfaces based upon its lack of absorption of light at wavelengths >290 nm(6). Biodegradation of benzotriflouride will not be an important fate process in soil according to two aqueous biodegradation tests(7).

Benzotrifluoride may volatilize from water surfaces based on an estimated Henry's Law constant of 0.017 atm-cu m/mole(SRC), calculated from experimental values of vapor pressure(4) and water solubility(5). Estimated half-lives for a model river and model lake are 3.6 hours and 4.8 days, respectively(3,SRC).

ATMOSPHERIC FATE: According to a suggested classification scheme(1), an experimental vapor pressure of 38.83 mm Hg at 25 °C(2,SRC) indicates that benzotrifluoride will exist in the vapor phase in the ambient atmosphere. Vapor-phase benzotrifluoride is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals(3); the half-life for this reaction in air is estimated to be about 35 days(3,SRC). Vapor-phase benzotrifluoride is also degraded in the atmosphere by reaction with ozone(4); the half-life for this reaction in air is estimated to be about 6.3 years(4,SRC). Particulate-phase benzotrifluoride may be physically removed from the air by wet and dry deposition(SRC). Benzotrifluoride will not be susceptible to direct photolysis based upon its lack of absorption of light at wavelengths >290 nm(5).

Two four-week biodegradation studies using 2 mg/L sludge and benzotrifluoride concentrations of 2.4 and 11.9 mg/L gave theoretical BODs of 0%(1).

The rate constant for the vapor-phase reaction of benzotrifluoride with photochemically produced hydroxyl radicals has been experimentally determined to be 4.6X10-13 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 35 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). The rate constant for the vapor-phase reaction of benzotrifluoride with ozone has been experimentally determined to be less than 5X10-21 cu cm/molecule-sec at 25 °C(2). This corresponds to an atmospheric half-life of about 6.3 years at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2,SRC). Benzotrifluoride will not be susceptible to direct photolysis based upon its lack of absorption of light at wavelengths >290 nm(3).

An estimated BCF value of 110 was calculated for benzotrifluoride(SRC), using an experimental log Kow of 3.01(1) and a recommended regression-derived equation(2). Bioconcentration factors determined from a six week study in carp using 100 and 10 ug/L benzotrifluoride were 26-54 and 31-58, respectively(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms will be an important fate process(SRC).

The Koc of benzotrifluoride is estimated as approximately 1030(SRC), using an experimental log Kow of 3.01(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that benzotrifluoride has low mobility in soil(SRC).

The Henry's Law constant for benzotrifluoride is estimated as 0.017 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 38.83 mm Hg(1), and water solubility, 451 mg/l(2). This value indicates that benzotrifluoride will volatilize rapidly from water surfaces(3,SRC). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is estimated as approximately 3.6 hours(3,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 4.8 days(3,SRC). Benzotrifluoride's high vapor pressure(1) and high Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil may occur(SRC).

SURFACE WATER: Benzotrifluoride has been qualitatively identified in the Niagara River(1).

Benzotrifluoride was detected in Bloody Run Creek water (downstream from the Hyde Park landfill) in Niagara Falls, NY at a level of 0.1-1 ppb or in sediment at a level of 0.5-2 ppm(1). Benzotrifluoride has been detected in one out of 63 industrial effluent samples taken from Ohio, West Virginia, Pennsylvania, New Jersey, New York, Louisiana, Kentucky, Delaware, and Texas at a concentration less than 10 ug/L(2).
