- 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 7 was calculated for n-pentanoic acid(SRC), using a log Kow of 1.39(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 140(SRC), determined from a log Kow of 1.39(2) and a regression-derived equation(3), indicates that n-pentanoic acid is expected to have high mobility in soil(SRC). The pKa of n-pentanoic acid is 4.84(4), indicating that this compound will partially exist 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(5). Volatilization of n-pentanoic acid from moist soil surfaces is not expected to be an important fate process(SRC) given a Henry's Law constant of 4.72X10-7 atm-cu m/mole(6). n-Pentanoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.96X10-1 mm Hg(7). n-Pentanoic acid is expected to be readily biodegradable in most environmental conditions based on several biodegradation tests where n-pentanoic acid reached 43%(8) to 68%(9) of its theoretical BODs in sewage inoculum after 5 days.

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 140(SRC), determined from a log Kow of 1.39(2) and a regression-derived equation(3), indicates that n-pentanoic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon a Henry's Law constant of 4.72X10-7 atm-cu m/mole(4). According to a classification scheme(5), an estimated BCF of 7(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). n-Pentanoic acid is expected to be readily biodegradable in most environmental conditions based on several biodegradation tests where n-pentanoic acid reached 43%(7) to 68%(8) of its theoretical BODs in sewage inoculum after 5 days. 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-pentanoic acid, which has an estimated vapor pressure of 1.96X10-1 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-pentanoic 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 3.9 days(SRC), calculated from its rate constant of 4.11X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).
