| DOT Emergency Guidelines | /GUIDE 128: FLAMMABLE LIQUIDS (NON-POLAR/WATER-IMMISCIBLE)/ Fire or Explosion: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substances may be transported hot./GUIDE 128: FLAMMABLE LIQUIDS (NON-POLAR/WATER-IMMISCIBLE)/ Health: Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution./GUIDE 128: FLAMMABLE LIQUIDS (NON-POLAR/WATER-IMMISCIBLE)/ Public Safety: CALL Emergency Response Telephone Number ... . As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering./GUIDE 128: FLAMMABLE LIQUIDS (NON-POLAR/WATER-IMMISCIBLE)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA).

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 3,500(SRC), determined from a log Kow of 3.99(2) and a regression-derived equation(3), indicates that 1-heptene is expected to have slight mobility in soil(SRC). Volatilization of 1-heptene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 0.421 atm-cu m/mole(SRC) determined from a vapor pressure of 59.3 mm Hg(4) and water solubility of 18.2 mg/l at 25 °C(5). The potential for volatilization of 1-heptene from dry soil surfaces may exist(SRC) based upon this compounds vapor pressure(4). 1-Heptene's linear hydrocarbon structure would suggest that biodegradation is an important process in soil(6).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3,500(SRC), determined from a log Kow of 3.99(2) and a regression-derived equation(3), indicates that 1-heptene is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected to occur rapidly(3) based upon the Henry's Law constant of 0.421 atm-cu m/mole(SRC) determined from a vapor pressure of 59.3 mm Hg(4) and water solubility of 18.2 mg/l at 25 °C(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3 and 94 hours, respectively(SRC). According to a classification scheme(6), an estimated BCF of 630(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is high(SRC). 1-Heptene's linear hydrocarbon structure would suggest that biodegradation is an important process in water(7).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-heptene, which has a vapor pressure of 59.3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-heptene 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 9.5 hours(SRC), calculated from its rate constant of 4.05X10-11 cu cm/molecule-sec at 25 °C(3). The rate constant for the gas-phase reaction of 1-heptene with ozone has been measured as 1.7X10-17 cu cm/molecule-sec at 25 °C(4). This corresponds to an atmospheric half-life of about 16 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(4). |

| Environmental Bioconcentration | An estimated BCF of 630 was calculated for 1-heptene(SRC), using a log Kow of 3.99(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). |

| Volatilization from Water/Soil | The Henry's Law constant for 1-heptene is estimated as 0.421 atm-cu m/mole(SRC) from its vapor pressure of 59.3 mm Hg(1) and water solubility of 18.2 mg/l at 25 °C(2). This Henry's Law constant indicates that 1-heptene is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 94 hours(SRC). 1-Heptene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1-heptene from dry soil surfaces may exist(SRC) based upon the vapor pressure of this compound(1). |

| Environmental Abiotic Degradation | The rate constant for the vapor-phase reaction of 1-heptene with photochemically-produced hydroxyl radicals has been measured as 4.05X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 9.5 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of 1-heptene with ozone has been measured as 1.7X10-17 cu cm/molecule-sec at 25 °C(2). This corresponds to an atmospheric half-life of about 16 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). 1-Heptene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). |
