The Henry's Law constant for methyl mercaptan is estimated as 0.0031 atm-cu m/mole(SRC) derived from its vapor pressure, 1,510 mm Hg(1), and water solubility, 15,400 mg/L(2). This Henry's Law constant indicates that methyl mercaptan 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 0.8 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)(3) is estimated as 2.8 days(SRC). Methyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces is expected to occur(SRC). Methyl mercaptan is expected to volatilize rapidly from dry soil surfaces based upon its vapor pressure and because it is a gas a temperatures above 6 deg C(SRC). However, gaseous methyl mercaptan gas has been found to strongly adsorb to moist and dry soil surfaces suggesting that adsorption might be an environmental sink for methyl mercaptan(4). Therefore, the importance of volatilization from soil surfaces may be attenuated by adsorption(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl mercaptan can be estimated to be 13(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl mercaptan is expected to have very high mobility in soil. Gaseous methyl mercaptan has been observed to partition to soils(3). For example, when gaseous methyl mercaptan was passed over six air-dried and moist (50% field capacity) soils, 2.4-32.1 mg/g and 2.2-21.4 mg/g of methyl mercaptan rapidly adsorbed to the dry and moist soils, respectively(3). Neither the capacity or rate of sorption was correlated to soil pH, organic matter content, or clay content; sterile controls ruled out the involvement of microorganisms(3); it was suggested that adsorption to soil surfaces might be an environmental sink for gaseous methyl mercaptan(3).

The Henry's Law constant for dimethyl sulfide has been measured as 1.61X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that dimethyl sulfide 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 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 3 days(SRC). Dimethyl sulfides's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of dimethyl sulfide from dry soil surfaces may exist(SRC) based upon a vapor pressure of 502 mm Hg(3).

The Koc of dimethyl sulfide is estimated as 6.3(SRC), using a water solubility of 22,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dimethyl sulfide is expected to have very high mobility in soil.

Literature: #Air-dried, unsterilized moist, and sterilized moist soils exposed to air initially containing 500 ppm dimethyl sulfide adsorbed an avg of 32, 308, and 10 ug dimethyl sulfide/g soil, respectively, in 15 days(1). Time required for complete sorption of dimethyl sulfide by moist soil from air initially containing 100 ppm dimethyl sulfide: soil 1 (Weller) - 1st exposure 150 min, 2nd exposure 100 min, 3rd exposure 95 min; soil 2 (Harps) - 1st exposure 45 min, 2nd exposure 24 min, 3rd exposure 19 min(1). These data suggest that moist soils have a greater tendency to adsorb dimethyl sulfide than dry soils, and that microbial activity in moist soils may be responsible for greater adsorption(1). When natural gas containing 0.5 pounds of dimethyl sulfide per million cubic feet of gas was passed through a bed of pulverized, dry, montmorillonite clay, dimethyl sulfide exhibited a fast breakthrough (2 hours) and a fast build-up rate in effluent gas (85% of influent concn 4 hours after breakthrough), suggesting that dimethyl sulfide does not adsorb to dry soils(2).

The Henry's Law constant for carbon disulfide is 1.44X10-2 atm-cu m/mole at 24 deg C(1). This Henry's Law constant indicates that carbon disulfide is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) (2) is approximately 2.6 hours(SRC). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) (2)is approximately 3.5 days(SRC). Carbon disulfide's Henry's Law constant(1) indicates that volatilization from moist soil surfaces is expected to occur(SRC). The potential for volatilization of carbon disulfide from dry soil surfaces may exist(SRC) based upon the vapor pressure of 359 mm Hg(3).

The Koc of carbon disulfide is estimated as approximately 270(SRC), using a log Kow of 1.94(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that carbon disulfide is expected to have moderate mobility in soil(SRC). The avg adsorption of carbon disulfide after 10 minutes by 4 air-dried soils was 46% but only 12% by the same soils at 50% water-holding capacity(4). However, after 8 hr the rate of adsorption was greater by moist soil, but only when the soil was unsterilized(4). Further experiments suggest that this 'adsorption' in moist soils is the result of microbial action(4).

The Henry's Law constant for dimethyl disulfide is reported as 1.21X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that dimethyl disulfide 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 3.5 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 4.1 days(SRC). Dimethyl disulfide's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). In a laboratory study, the volatilization rate of dimethyl disulfide from a tidal marsh soil (at field capacity or 1.5 field capacity) ranged from 0.1 to 0.4 ng (sulfur basis)/min(3). Dimethyl disulfide is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 28.7 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of dimethyl disulfide can be estimated to be 40(SRC). According to a classification scheme(2), this estimated Koc value suggests that dimethyl disulfide is expected to have very high mobility in soil. Gas chromatographic studies with various air-dry and moist soils have shown that soil can sorb atmospheric, gas phase dimethyl disulfide(3). In one closed-system test, 17-94% of input dimethyl disulfide was sorbed by the soil in 10 min(3); in a 15-day test, dimethyl disulfide sorption was 101-306 ug sorbed/g soil(3). Soil microbes were found to be important for the gas phase sorption of dimethyl disulfide as 15-day sorption in sterilized soil was only 9-98 ug sorbed/g soil(3).

The Henry's Law constant for 1-undecene is estimated as 1.48 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1-undecene 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 hr(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 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 21 days in a model pond 2 m deep, and one in which the effect of adsorption was ignored, yielding an estimated half-life of 42 hrs in a model pond 2 m deep(3). 1-Undecene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). 1-Undecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.493 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-undecene can be estimated to be about 3180(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-undecene is expected to have slight mobility in soil.
