1-Tridecene

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 11,000(SRC), determined from a structure estimation method(2), indicates that 1-tridecene is expected to be immobile in soil(SRC). Volatilization of 1-tridecene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.61 atm-cu m/mole(SRC), using a fragment constant estimation method(3). The potential for volatilization of 1-tridecene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 6.38X10-2 mm Hg(4). However, adsorption to soil is expected to attenuate volatilization(SRC). Based on biodegradation studies for 1-octadecene, 1-tridecene is also expected to biodegrade in soil(SRC). Using a ready biodegradation test, 1-octadecene was degraded with 39-48% of theoretical oxygen demand being consumed in 28 days(5).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 11,000(SRC), determined from a structure estimation method(2), indicates that 1-tridecene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.61 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.4 hrs and 5.3 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 29 years if adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 750(SRC), from an estimated log Kow of 6.6(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Based on biodegradation studies for 1-octadecene, 1-tridecene is also expected to biodegrade in the aqueous environment(SRC). Using a ready biodegradation test, 1-octadecene was degraded with 39-48% of theoretical oxygen demand being consumed in 28 days(9).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-tridecene, which has a vapor pressure of 6.38X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase 1-tridecene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone(SRC); the half-lives for these reactions in air are estimated to be 9.6 hrs and 23 hrs, respectively(SRC). The half-life for reaction with photochemically-produced hydroxyl radicals was calculated from its rate constant of 4.01X10-11 cu cm/molecule-sec at 25 °C(3). The half-life for reaction with photochemically-produced ozone was calculated from its rate constant of 1.20X10-17 cu cm/molecule-sec at 25 °C(3,4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-tridecene can be estimated to be 11,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-tridecene is expected to be immobile in soil(SRC).

AEROBIC: Based on biodegradation studies for 1-octadecene, 1-tridecene is also expected to biodegrade in the aqueous environment(SRC). Using a ready biodegradation test, 1-octadecene was degraded with 39-48% of theoretical oxygen demand being consumed in 28 days(1).

An estimated BCF of 750 was calculated for 1-tridecene(SRC), using an estimated log Kow of 6.59(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).

The Henry's Law constant for 1-tridecene is estimated as 2.61 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1-tridecene is expected to volatilize rapidly from water surfaces(2). 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 1.4 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 5.3 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 29 years if adsorption is considered(3). 1-Tridecene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). However, volatilization from moist soil surfaces is expected to be attenuated by adsorption to soil in the water column(SRC). 1-Tridecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.38X10-2 mm Hg(4).

The rate constant for the vapor-phase reaction of 1-tridecene with photochemically-produced hydroxyl radicals is 4.0X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 9.6 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of 1-tridecene with ozone has been estimated as 1.20X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1). This corresponds to an atmospheric half-life of about 23 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). 1-Tridecene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum (>290 nm)(SRC).

1-Tridecene's production and use as an alpha-olefin intermediate may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 6.28X10-2 mm Hg at 25 °C indicates 1-tridecene will exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-tridecene will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone; the half-lives for these reactions in air are estimated to be 9.6 and 23 hrs, respectively. If released to soil, 1-tridecene is expected to have no mobility based upon an estimated Koc of 11,000. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 2.6 atm-cu m/mole. However, adsorption to soil is expected to attenuate volatilization. Based on biodegradation studies for 1-octadecene, 1-tridecene is also expected to biodegrade. Using a ready biodegradation test, 1-octadecene was degraded with 39-48% of theoretical oxygen demand being consumed in 28 days. If released into water, 1-tridecene is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 1.4 hrs and 5.3 days, respectively. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 29 years if adsorption is considered. An estimated BCF of 750 suggests the potential for bioconcentration in aquatic organisms is high. Occupational exposure to 1-tridecene may occur through inhalation and dermal contact with this compound at workplaces where 1-tridecene is produced or used. (SRC)
