SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: 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. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)|Flammable. Above 46 °C explosive vapour/air mixtures may be formed.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

The hydrocarbon content of the exhaust of two different turbojet engines operated at simulated supersonic flight conditions was determined. During the experiment, jet engine model YJ93-GE-3 contained 1-decene in its exhaust ranging from 0.33-42.3 ppm while jet engine model J85-GE-5B contained 1-decene in its exhaust ranging from 0.31-1.25 ppm(1). The use of various types of plastic films for mulch purposes (ground moisture and weed control) on farmlands can lead to the release of 1-decene into the ambient environment through its disposal. Typically, these plastic films are burned either in situ in the crop row or gathered into large piles and incinerated. In one controlled study, 1-decene was detected (concn not specified) in the gas released during the burning of this type of plastic(2). Landfill gas from eight different sites in the United Kingdom was analyzed for trace compounds, including 1-decene. In one crude municipal landfill located in a stone quarry, with an age of 5-6 years, 1-decene was detected at 62 mg/cu m, 3m below the surface of the landfill and at 29.9 mg/cu m, 15 cm above the landfill(3). At another landfill comprised of municipal, industrial and liquid waste in a clay pit, with an age greater than 15 months, 1-decene was detected at 42 mg/cu m 4 meters below the surface of the landfill(3). 1-Decene has been reported to be a constituent of exhaust gas from diesel engines(4). Grab samples of 63 effluent were collected and analyzed from several chemical manufacturers located across the United States(5). These locations included Ohio, West Virginia, Pennsylvania, New Jersey, New York, Louisiana, Kentucky, Delaware, and Texas. 1-Decene was detected, concentration not specified, in 2 out of the 63 effluent grab samples taken from September 30, 1976 to November 30, 1978(5).

URBAN/SUBURBAN: 1-Decene was detected, concentration not specified, in five urban air analyses carried out in Leningrad, U.S.S.R. from July-October 1976(1). In another urban air study, 1-decene was detected, concentration not specified, in urban air samples from Leningrad, Tashkent, Baku, Tbilisi, Kemerovo, and Murmansk U.S.S.R. in 1977(2).

practically nontoxic

1-Decene is found as a naturally occurring compound emitted by various plant types in California's Central Valley(1) and woodland vegetation located across the United States(2). 1-Decene is also a naturally occurring compound found as part of the volatile organic compounds emitted during the heating of soybean, rapeseed, peanut and Canola oil(3).

PRESENT IN JET AIRCRAFT EMISSIONS, SIMULATED HIGH ALTITUDE.|1-Decene's production and use in the synthesis of perfumes, flavors, pharmaceuticals, dyes, oils, and resins(1) may result in its release to the environment through various waste streams(SRC). Also, the burning of plastic films used in agriculture(2) and the combustion of jet fuel(3) are potential sources of 1-decene in the environment.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1720(SRC), determined from a structure estimation method(2), indicates that 1-decene is expected to have low mobility in soil(SRC). Volatilization of 1-decene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.68 atm-cu m/mole(SRC), from its vapor pressure of 1.67(3) and a water solubility of 0.115(4). The potential for volatilization of 1-decene from dry soil surfaces may exist(SRC) based upon its vapor pressure(3). However, adsorption to soil is expected to attenuate volatilization(SRC). 1-Decene's linear hydrocarbon structure would suggest that biodegradation is an important process in soil(5).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1720(SRC), determined from a structure estimation method(2), indicates that 1-decene is expected to adsorb to sediment and suspended solids in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.68 atm-cu m/mole(SRC), developed from a vapor pressure of 1.67(4) and a water solubility of 0.115(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.2 hrs and 5 days, respectively(SRC). However, this model underestimates the volatilization half-life of 1-decene since it does not take into account the effects of adsorption. This is apparent from the results of two EXAMS model runs, one in which the effect of adsorption was considered (half-life = 11 days in a model pond) and one in which adsorption was ignored (half-life = 40 hrs in a model pond)(6). 1-Decene's linear hydrocarbon structure would suggest that biodegradation is an important process in water(7). According to a classification scheme(8), an estimated BCF of 488(SRC), from a log Kow(9) and a regression-derived equation(10), suggests the potential for bioconcentration in aquatic organisms is high. 1-Decene is degraded in water by reaction with hydroxyl radicals(SRC); the half-life for this reaction in water is estimated to be 111 days(SRC), calculated from its rate constant of 7.22X10+9/M sec at 25 °C(11,12).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-decene, which has a vapor pressure of 1.67 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-decene 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 11 hrs(SRC), calculated from its rate constant of 3.5X10-11 cu cm/molecule-sec at 25 °C(3). Vapor-phase 1-decene is degraded by ozone in the atmosphere; the half-life for this reaction in air is estimated to be 25 hrs(SRC), calculated from its rate constant of 1.08X10-17 cu m/molecule-sec(4). 1-Decene is also degraded by nitrate in the ambient atmosphere; the half-life for this reaction in air is estimated to be 1 day, calculated from its rate constant of 3.24X10-14 cu cm/molecule sec(3,5).

The rate constant for the vapor-phase reaction of 1-decene with photochemically-produced hydroxyl radicals is 3.5X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 11 hrs at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). The rate constant for the vapor-phase reaction of 1-decene with ozone is 1.08X10-17 cu m/molecule-sec(3). This corresponds to an atmospheric half-life of about 25 hrs(SRC) at an atmospheric concentration of 7X10+11 ozone per cu cm(3). The rate constant for the vapor-phase reaction of 1-decene with nitrate is 3.24X10-14 cu cm/molecule sec(1). This corresponds to an atmospheric half-life of about 1 day(SRC) at an atmospheric concentration of 2.4X10+8 nitrate per cu cm during a 12 hour night time period(4). 1-Decene is degraded in water by reaction with hydroxyl radicals(SRC); the half-life for this reaction in water is estimated to be 111 days(SRC), calculated from its rate constant of 7.22X10+9/M sec at 25 °C(1,5). 1-Decene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(6) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum.

An estimated BCF of 488 was calculated for 1-decene(SRC), using a log Kow of 5.70(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.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-decene can be estimated to be about 1720(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-decene is expected to have low mobility in soil.

The Henry's Law constant for 1-decene is estimated as 2.68 atm-cu m/mole(SRC) from its vapor pressure, 1.67 mm Hg(1), and water solubility, 0.115 mg/l(2). This Henry's Law constant indicates that 1-decene 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)(3) is estimated as 1.2 hrs(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 5 days(SRC). However, the volatilization half-life does not take into account the effects of adsorption. This is apparent from the results of two EXAMS model runs, one in which the effect of adsorption was considered, yielding an estimated half-life of 11 days in a model pond 2 m deep, and one in which the effect of adsorption was ignored, yielding an estimated half-life of 56 hours in a model pond 2 m deep(4). 1-Decene's Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1-decene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 1.67 mm Hg(1).

SURFACE WATER: 1-Decene was detected, concentration not specified, in northern and southern Lake Michigan water basin in 1982(1).

The volatile vapor fraction emitted during the heating of four oils (rapeseed, Canola, peanut and soybean) was analyzed to determine the concentrations of various volatile organic compounds. 1-Decene was detected, concentration not specified, in all four heated oils(1). In another study specifically of peanut oil, 1-decene was detected in head space air samples when peanut oil was heated from 50-200 °C(2). The highest concentration of 1-decene occurred at 200 °C.

Occupational exposure to 1-decene may occur through inhalation and dermal contact with this compound at workplaces where soybean, peanut, rapeseed, or Canola oils are used(1), at landfill operations(2), on farmlands(3), or where 1-decene is produced or used(SRC). Chinese restaurants are known for their use of peanut and rapeseed oils and may therefore present a potential source of 1-decene exposure to the cooks(1). The general population may be exposed to 1-decene via ingestion of food(1).
