- Toxicity Summary: IDENTIFICATION AND USE: Decane is a colorless liquid. It is used in organic synthesis, as a solvent, standardized hydrocarbon, and in jet-fuel research. HUMAN EXPOSURE AND TOXICITY: In tests with human subjects, solutions as strong as 30% produced no irritation when applied to skin and left for 24 hr. Decane is a simple asphyxiant and causes CNS depression in high concentrations. ANIMAL STUDIES: Rats exposed to decane vapor have been examined for lens opacities, but no cataracts were found. Rats exposed to 0.2 mL of decane by inhalation died within 24 hr by pulmonary edema and hemorrhaging. Decane is highly lipid-soluble and causes pulmonary pneumonitis when aspired into lungs. Animals showed signs of dyspnea, tachypnea, and cyanosis. In rats exposed by inhalation decane caused some limited, but statistically significant neurobehavioral effects at 5 g/cu m, with no effects at 1.5 g/cu m. Exposure of rats to 540 ppm of decane 18 hr/day, 7 days/week for 57 days stimulated weight gains and decreased the total white blood count, but no bone marrow changes or other organ changes were noted. Dermal application of undiluted decane to mice (0.1-0.15 g per mouse, 3 times a week for 50 weeks Source: Hazardous Substances Data Bank (HSDB)
- Environmental Bioconcentration: An estimated BCF of 40 was calculated in fish for n-decane(SRC), using a log Kow of 5.01(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1500(SRC), determined from a structure estimation method(2), indicates that n-decane is expected to have low mobility in soil(SRC). Volatilization of n-decane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 5.15 atm-cu m/mole(SRC) derived from its vapor pressure, 1.43 mm Hg(3), and water solubility, 0.052 mg/L(4). n-Decane is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure. Biodegradation studies in soil have observed volatilization to be a more important removal process than biodegradation for n-decane(5,6). A 77-85.8% of theoretical biodegradation using activated sludge in several OECD 301F tests indicates n-decane is readily biodegradable(7) and suggests that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1500(SRC), determined from a structure estimation method(2), indicates that n-decane is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 5.15 atm-cu m/mole(SRC), derived from its vapor pressure, 1.43 mm Hg(4), and water solubility, 0.052 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3.5 hours and 4.7 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 40(SRC), from its log Kow of 5.01(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). A 77-85.8% of theoretical biodegradation using activated sludge in several OECD 301F tests indicates n-decane is readily biodegradable(8) and suggests that biodegradation is an important environmental fate process in water(SRC). Die-away tests using sea-water from the Narragansett Bay and radio-labeled decane showed that 71-82% of the radio-labeled n-decane was mineralized to 14CO Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-decane, which has a vapor pressure of 1.43 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-decane 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 35 hours(SRC), calculated from its rate constant of 1.1X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase n-decane is also degraded in the atmosphere by reaction with nitrate radicals(SRC); the half-life for this reaction in air is estimated to be 124 days(SRC), calculated from its rate constant of 2.59X10-16 cu cm/molecule-sec at 25 °C(4). n-Decane has been detected in rain and snow samples(5,6) suggesting that n-decane may be removed from the air by wet deposition(SRC). n-Decane does not contain chromophores that absorb at wavelengths >290 nm(7) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
