  • Health Effects: Pentane is a central nervous system depressant and can cause loss of consciousness and coma at high doses. Ingestion may cause pulmonary toxicity due to pentane aspiration, including chemical pneumonitis, acute lung injury, and hemorrhage. Cardiovascular effects may include ventricular dysrhythmias and sudden death. (T29, A600) Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: Pentane is a central nervous system depressant. It affects the peripheral nervous system through demyelinization and axonal degeneration. (T29) Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 80 was calculated for n-pentane(SRC), using a log Kow of 3.39(1) and a regression-derived equation(2). According to a classification scheme(3), 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 72(SRC), determined from a structure estimation method(2), indicates that n-pentane is expected to have high mobility in soil(SRC). Volatilization of n-pentane from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.25 atm-cu m/mole(3). n-Pentane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 514 mm Hg at 25 °C(4). Screening studies have shown that n-pentane is biodegradable under aerobic conditions(5,6), and these studies suggest that this compound will biodegrade in soil; however, volatilization from soil is expected to be the dominant environmental fate process of n-pentane(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 72(SRC), determined from a structure estimation method(2), indicates that n-pentane 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 1.25 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.5 hrs and 3.4 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 80(SRC), from its log Kow of 3.39(6) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Screening studies have shown that n-pentane is biodegradable under aerobic conditions(8,9), and these studies suggest that this compound will biodegrade in water; however, volatilization from water surfaces is expected to be the dominant environmental fate process of n-pentane(SRC). 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-pentane, which has a vapor pressure of 514 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-pentane 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 3 days(3), calculated from its rate constant of 3.94X10-12 cu cm/molecule-sec at 25 °C(4). n-Pentane does not contain chromophores that absorb at wavelengths >290 nm(5) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
