- 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. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; 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.

- Environmental Bioconcentration: An estimated BCF of 490 was calculated for methyl oleate(SRC) using a log Kow of 7.45(1) and a regression-derived equation(2). According to a classification scheme(3), the estimated BCF suggests the potential for bioconcentration in aquatic organisms is moderate. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that methyl oleate is expected to be immobile in soil(SRC). Volatilization of methyl oleate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.014 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Methyl oleate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.3X10-6 mm Hg(4). Methyl oleate is expected to rapidly biodegrade in aerobic soils as suggested by the rapid biodegradation of structurally similar long-chain fatty acid esters(5-7).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that methyl oleate is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 0.014 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Volatilization half-lives for a model river and model lake are 5 hours and 7 days, respectively(SRC), using an estimation method(3). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The volatilization half-life from a model pond is estimated to be about 61 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 18 months(5). According to a classification scheme(6), an estimated BCF of 490 from its log Kow of 7.45(12) and a regression-derived equation suggests the potential for bioconcentration in aquatic organisms is moderate. Methyl oleate is expected to rapidly biodegrade in aerobic soils as suggested by the rapid biodegrad 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), methyl oleate, which has a vapor pressure of 6.3X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methyl oleate 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 7.5 hours(SRC) from its estimated rate constant of 7.4X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase methyl oleate is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for this reaction in air is estimated to be 2.1 hours(SRC) from its estimated rate constant of 1.3X10-16 cu cm/molecule-sec at 25 °C(3). Particulate-phase methyl oleate may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
