SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye.

n-Propyl acetate is found as a plant volatile in many fruits and plants(1-4).

n-Propyl acetate's production and use as flavoring agents, in perfumery, as a solvent for nitrocellulose and other cellulose derivatives, in natural and synthetic resins, lacquers, plastics, for organic synthesis, and a lab reagent(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that n-propyl acetate is expected to have very high mobility in soil(SRC). Volatilization of n-propyl acetate from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 2.18X10-4 atm-cu m/mole(3). n-Propyl acetate is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 35.9 mm Hg at 25 °C(4). A 81.0% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is an important environmental fate process in soil(SRC).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that n-propyl acetate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 2.18X10-4(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 7 hours and 5.2 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of 1.24(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). n-Propyl acetate gave a 5- and 10-day theoretical BOD of 62% and 80%, respectively, using a settled domestic wastewater seed(8). When the same inoculum was added to sea water, n-propyl acetate 5- and 10-day theoretical BOD was 50% and 70%(8), indicating biodegradation in water is important(SRC). Hydrolysis is expected to occur slowly based on hydrolysis half-lives of about 3 years, 119 days and 12 days at pH 7, 8 and 9, respectively(9).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-propyl acetate, which has a vapor pressure of 35.9 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-propyl acetate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4.7 days(SRC), calculated from its rate constant of 3.4X10-12 cu cm/molecule-sec at 25 °C(3). n-Propyl acetate does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of n-propyl acetate with photochemically-produced hydroxyl radicals has been reported as 3.4X10-12 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 4.7 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Based on an experimentally determined hydrolysis rate constant of 0.067 L/mol-sec at 25 °C(2), the hydrolysis half-lives of n-propyl acetate at pH 7, 8, and 9 are 3.3 years, 119 days, and 12 days, respectively(SRC). n-Propyl acetate does not contain chromophores that absorb at wavelengths >290 nm(3) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 3 was calculated in fish for n-propyl acetate(SRC), using a log Kow of 1.24(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-propyl acetate can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-propyl acetate is expected to have very high mobility in soil.

The Henry's Law constant for n-propyl acetate is reported as 2.18X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that n-propyl acetate is expected to volatilize from water surfaces(2). 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)(2) is estimated as 7 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 5.2 days(SRC). n-Propyl acetate's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Propyl acetate is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 35.9 mm Hg(3).

SURFACE WATER: n-Propyl acetate was identified, not quantified, in water samples taken from the River Lee, in the UK(1) and in 1 out of 8 rivers studied in Germany(2).

n-Propyl acetate was identified, not quantified as a component of concord grape juice essence(1), as a volatile flavor component of Beaufort cheese(2), ripening bananas(3), Kogyoke apples(4) and pork(5). n-Propyl acetate was identified as a volatile component of the blended fruit of nectarines, and also in a head-space analysis of the intact fruit(6). n-Propyl acetate was detected at a concentration of 6.5 ppb in fresh grapefruit juice(7).

According to the 2006 TSCA Inventory Update Report, the number of workers reasonably likely to be exposed in the industrial manufacturing, processing, and use for n-propyl acetate is 1000 or greater persons; the data may be greatly underestimated(1).|NIOSH (NOES Survey 1981-1983) has statistically estimated that 46,856 workers (11,660 of these were female) were potentially exposed to n-propyl acetate in the US(1). Occupational exposure to n-propyl acetate may occur through inhalation and dermal contact with this compound at workplaces where n-propyl acetate is produced or used(SRC). n-Propyl acetate was found in 1 air sample taken from 11 different auto paint shops in Spain at a concentration of 36.5 mg/cu m(2). n-Propyl acetate was detected in 3% of the air samples taken from printing industries in Belgium collected beginning in 1983(3). Monitoring data indicate that the general population may be exposed to n-propyl acetate via inhalation of ambient air, ingestion of food containing n-propyl acetate(SRC).

n-Propyl acetate was detected in 49.4% of 387 expired air samples obtained from 54 non-smoking volunteers from Chicago, IL, at a mean concentration of 2.4 ng/L(1). n-Propyl acetate was described as a normal component of expired air(2). n-Propyl acetate was detected in 4 out of 10 expired air samples taken from 8 smoking and non-smoking male volunteers from TX, at concentrations ranging from trace to 2.0 ug/hr, averaging 1.39 ug/hr for the positive samples(3).

Method: NIOSH 1450, Issue 3; Procedure: gas chromatography with flame ionization; Analyte: n-propyl acetate; Matrix: air; Detection Limit: 0.9 ug/sample.|Gas chromatography was used to determine propyl acetate in air.|Propyl acetate was one of the organic solvent products which were collected in factories nationwide in Japan and analyzed by gas chromatography.|N-propyl acetate was identified in laminated plastic material used in food packages by gas chromatographic and gas chromatographic-mass spectrometric methods.|A gas chromatographic method for the analysis of N-propyl acetate, consists of a stainless steel column, 3m x 3 mm, packed with chromosorb WHP (100/120 mesh) coated with 5% FFAP, with hydrogen-air flame ioniztion delection, and nitrogen as the carrier gas at a flow rate of 30 mL/min, is a NIOSH approved method. A sample injection volume of 5 uL is suggested. The column temperature is 70 °C and a detector temperature of 250 °C. This method has a detection limit of 0.02, over a working range of 84-2520 mg/cu m for a 10 liter sample.
