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 isopentanol is 1.41X10-5 atm-cu m/mol(1). Using this value for the Henry's Law constant, one can estimate that the volatilization half-life of isopentanol in a model river 1 m deep flowing at 1 m/s with a wind speed of 3 m/s is 2.55 days(2). Similarly, the half-life of isopentanol in a model lake 1 m deep with a 0.05 m/s current and a 0.5 m/s wind is 21 days(2). In view of isopentanol's relatively high vapor pressure, 2.37 mm Hg at 25 deg C(3) and moderate Henry's Law constant and low adsorptivity to soil, isopentanol would be expected to volatilize from dry and moist soil(SRC).
Literature: (1) Butler JAV et al; J Chem Soc 1935: 280-5 (1935) (2) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. NY: McGraw-Hill Chapt 15 (1982) (3) Riddick JA et al; Organic Solvents 4th ed; pp. 221-2 NY: Wiley (1986)

The Koc for isopentanol estimated from its water solubility, 26.7 mg/L(1), using recommended regression equations are 720(2) and 679(4). However, the chemicals used in developing these equations were mainly pesticides and their structures are not similar to isopentanol. The Koc for isopentanol estimated from molecular structure is 4(3). This should be a reasonable estimate for the Koc because it is close to the experimental value for the structurally similar chemical, 1-pentanol, 1.6(6). According to a suggested classification scheme(5), the estimated Kocs based on molecular structure suggests that isopentanol is very highly mobile in soil(SRC).

An experimental Henry's Law constant of 1.69X10-4 atm cu m/mole at 25 deg C(1) indicates that 2-heptanone 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 4.8 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)(2) is estimated as 6 days(SRC). 2-Heptanone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2-Heptanone is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.86 mm Hg(3).

The Koc of 2-heptonone is estimated as 280(SRC), using a log Kow of 1.98(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-heptanone is expected to have moderate mobility in soil.

Selenium volatilizes from soils at rates that are modified by temperature, moisture, time, season or year, concentration of water soluble selenium, and microbiological activity. Conversion of inorganic and organic selenium compounds to volatile selenium compounds (such as dimethyl selenide, dimethyl diselenide, and an unknown compound) by microorganisms has been observed in lake sediments of the Sudbury area of Ontario. This conversion may have been effected by pure cultures of Aeromonas, Flavobacterium, Pseudomonas, or an unidentified fungus, all of which are found in methylated lake sediments. Production of volatile selenium is temperature dependent. Compared with the amount of dimethyl Se produced at an incubation temperature of 20 deg C, 25% less was produced at 10 deg C and 90% less at 4 deg C.

The Kd values measured in unamended, manure-amended and gluten-amended Hanford sandy loam at 4 deg C were 0.038, 0.091 and 0.045, respectively; there was no detection at temperatures of 21 and 40 deg C, or in Losthill clay loam under the same conditions(1).

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).
