  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whene Source: CAMEO Chemicals

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for heptanoic acid(SRC), using a log Kow of 2.42(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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 490 for the free acid(SRC), determined from a log Kow of 2.42(2) and a regression-derived equation(3), indicates that undissociated heptanoic acid is expected to have moderate mobility in soil(SRC). The pKa of heptanoic acid is 4.8(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of heptanoic acid from moist soil is not expected to be an important fate process because the acid is in the anion form and anions do not volatilize(SRC). Heptanoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.07X10-2 mm Hg(5). Total organic carbon removal of 96% observed for heptanoic acid using a non-acclimated activated sludge(6), suggesting that biodegradation is an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 490 for the free acid(SRC), determined from a log Kow of 2.42(2) and a regression-derived equation(3), indicates that undissociated heptanoic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 4.8(4) indicates heptanoic acid will exist almost entirely 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(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Heptanoic acid, present at an initial concentration of 500 ppm, was biodegraded 24.6, 36.1, and 49.2% of its theoretical BOD after 72 hours using activated sludge(8), indicating biodegradation may be an important fate process in aqueous environments(SRC).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), heptanoic acid, which has a vapor pressure of 1.07X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase heptanoic acid 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 2.3 days(SRC), calculated from its rate constant of 6.9X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Heptanoic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
