Butyl benzoate was qualitatively detected in water samples collected from advanced waste treatment facilities in Lake Tahoe, CA (Oct 24, 1974), Orange County, CA (Jan-Feb, 1976), and Blue Plains, Washington DC (Sep 20, 1974)(1).

Butyl benzoate has been identified as a volatile component of dalieb fruit (edible fruit of a palm tree that grows along the Nile River)(1). Butyl benzoate has been identified as a volatile component of papaya fruit, babaco fruit and green peas(2-4).

Butyl benzoate is commonly used as a dye carrier during textile dyeing operations and is released in the wastewaters that result from dyeing operation(1-2).

TERRESTRIAL FATE: Biodegradation is expected to be the major degradation process in soil. Two biodegradation screening studies have found butyl benzoate to be readily biodegradable(1-2). A measured Koc value of 125(3) suggests that butyl benzoate will be mobile in soil. Its detection in environmental ground waters(4) indicates that it can leach(SRC).|AQUATIC FATE: Biodegradation is expected to be the major degradation process in natural water. Two biodegradation screening studies have found butyl benzoate to be readily biodegradable(1-2). Some volatilization may occur. The volatilization half-lives from a model environmental river (1 meter deep) and model pond have been estimated to be 33 hours and 20 days, respectively(3,4). Aquatic bioconcentration and adsorption to sediment are not expected to be important fate processes(SRC).|ATMOSPHERIC FATE: Based upon an extrapolated vapor pressure of 0.01 mm Hg at 25 °C(1), butyl benzoate is expected to exist almost entirely in the vapor-phase in the ambient atmosphere(2). It will degrade in an average ambient atmosphere by reaction with photochemically produced hydroxyl radicals (estimated half-life of about 3.25 days)(3,SRC).

The rate constant for the vapor-phase reaction of butyl benzoate with photochemically produced hydroxyl radicals has been estimated to be 4.94X10-12 cu cm/molecule-sec at 25 °C which corresponds to an atmospheric half-life of about 3.25 days at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm(1,SRC). The aqueous hydrolysis rate constant has been estimated to be 0.03204 L/mole-sec at 25 °C(4) which corresponds to aqueous hydrolysis half-lives of 6.9 yrs, 250 days and 25 days at pH 7, 8 and 9, respectively(2,SRC).

Based upon a reported water solubility of 59 mg/L(1), the BCF for butyl benzoate can be estimated to be 62 from a recommended regression-derived equation(2,SRC). This BCF value suggests that bioconcentration in aquatic organisms is not important(SRC).

125.89 L/kg|A Koc of 125 was experimentally determined for butyl benzoate(1); this Koc value indicates high soil mobility(2).

Based upon a water solubility of 59 mg/L(1) and an extrapolated vapor pressure of 0.01 mm Hg at 25 °C(2), the Henry's Law constant for butyl benzoate can be estimated to be 3.97X10-5 atm cu m/mole; a Henry's Law constant of this magnitude indicates that volatilization from environmental waters is possible, but should not be rapid(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep flowing 1 m/sec with a wind velocity of 3 m/sec) can be estimated to be about 33 hours(3,SRC). Volatilization half-life from an model environmental pond (2 meters deep) can be estimated to be about 20 days(4,SRC).

DRINKING WATER: Butyl benzoate was qualitatively detected in drinking water samples collected from treatment facilities in Miami, FL (Feb 2, 1976), New Orleans, LA (Jan 14, 1976), and Philadelphia, PA (Feb 10, 1976)(1).|SURFACE WATER: A butyl benzoate conc of 0.5 ppb was detected in water samples collected from the Merrimack River (MA) between April 1972 and Jan 1973(1); the source of the compound was thought to be textile and dye facilities located on the river(1).|GROUNDWATER: A maximum butyl benzoate conc of 3 ug/L was detected during groundwater monitoring studies conducted in the Netherlands (specific sites and dates not reported)(1).

Butyl benzoate has been identified as a volatile component of dalieb fruit (edible fruit of a palm tree that grows along the Nile River)(1). Butyl benzoate has been identified as a volatile component of papaya fruit, babaco fruit and green peas(2-4). It has been identified in molasses aroma(5).

Butyl benzoate occurs naturally as a volatile component of various fruits and vegetables(1-4); therefore, the general population is exposed through oral consumption. Residual amounts of butyl benzoate have been detected on cloth commercially dyed using butyl benzoate as a dye carrier(5); therefore, dermal exposure will be possible. Occupational exposure to butyl benzoate may occur through dermal contact and inhalation of vapor(SRC).|THERE ARE NO REPORTS OF ANY INJURY FROM ITS INDUSTRIAL USE. /BENZOIC ACID ESTERS/|NIOSH (NOES Survey 1981-1983) has statistically estimated that 16,661 workers are potentially exposed to butyl benzoate in the USA(1). NIOSH (NOHS Survey 1972-1974) has statistically estimated that 3,196 workers are potentially exposed to butyl benzoate in the USA(2).
