  • Toxicity Summary: IDENTIFICATION AND USE: 1-Nitropropane (1-NP) is a colorless liquid. 1-NP is used as a rocket propellant, gasoline additive, and in chemical syntheses. HUMAN STUDIES: Anorexia, nausea, vomiting, and intermittent diarrhea and headaches occurred in men exposed at 20 to 45 ppm of 1-NP during a dipping processes. Additionally, human exposure to 1-NP concentrations exceeding 100 ppm reportedly causes eye irritation in humans. ANIMAL STUDIES: Exposures at 5,000 ppm of 1-NP for 3 hr killed rabbits and guinea pigs. However, concentration of 10,000 ppm for 1 hr was not lethal. Signs of 1-NP exposure included conjunctival irritation, lacrimation, slow respiration with some rales, incoordination, ataxia, and weakness. Rats treated with 1-NP at 1 mmol/kg bw three times per week for 16 weeks had only slightly reduced body weight, and after 26 weeks (termination of treatment), they regained their body weight. One benign liver tumor was observed in these rats. Hepatotoxic symptoms were also observed. There have been numerous studies on the mutagenic activity of 1-NP in Salmonella typhimurium (Ames test). 1-NP was not mutagenic in multiple strains of S. typhimurium with or without the addition of Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: A BCF value of 1.3 was measured for fish (Golden ide) in a static 3-day test with 1-nitropropane present at 50 ppb(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). Bioconcentration of 1-nitropropane in algae (Chlorella fusca) was measured using (14)C-labelled 1-nitropropane at 50 ppb. The algae were irradiated for 24 hours; 92.9% of the radioactivity was present in solution, 1.7% of the radioactivity was associated with the algae(1). A bioconcentration factor of 180 for algae was calculated from this experiment(1). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 36(SRC), determined from a structure estimation method(2), indicates that 1-nitropropane is expected to have very high mobility(SRC). The pKa of 1-nitropropane is 8.98(3), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of 1-nitropropane from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 8.7X10-5 atm-cu m/mole(3). 1-Nitropropane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 10.1 mm Hg at 25 °C(5). Using the Closed Bottle test, 45% degradation in 4 weeks using an activated sludge inoculum(6) suggests that biodegradation may be 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 36(SRC), determined from a structure estimation method(2), indicates that 1-nitropropane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization of the neutral species from water surfaces is expected(3) based upon a Henry's Law constant of 8.70X10-5 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 12 hrs and 7 days, respectively(SRC). A pKa of 8.98(5) indicates 1-nitropropane will exist partially in the anion form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process for the ionized species(SRC). According to a classification scheme(6), a BCF of 1.3(7) indicates that bioconcentration in aquatic organisms is low(SRC). Using the Closed Bottle test, 45% degradation in 4 weeks using an activated sludge inoculum(7) suggests that biodegradation may be an important environmental fate process in water(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), 1-nitropropane, which has a vapor pressure of 10.1 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-nitropropane 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 37 days(SRC), calculated from its rate constant of 4.40X10-13 cu cm/molecule-sec at 25 °C(3). 1-Nitropropane 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).
