| 환경 거동 | TERRESTRIAL FATE: An estimated Koc value of 4(1) for 2,5-dihydrothiophene 1,1-dioxide indicates high mobility in soil(2) and leaching may occur. No data were located which suggest biodegradation is an important terrestrial fate process of 2,5-dihydrothiophene 1,1-dioxide(SRC).AQUATIC FATE: Based on an estimated Koc value of 4 and an estimated BCF value of 4.7(1), 2,5-dihydrothiophene 1,1-dioxide is not expected to adsorb to sediment or bioconcentrate in aquatic organisms. A volatilization half-life of 225 days has been estimated for a model river (one meter deep) suggesting slow volatilization from shallow rivers(1,SRC). No data were located which suggest biodegradation is an important environmental fate process of 2,5-dihydrothiophene 1,1-dioxide in aquatic systems(SRC).ATMOSPHERIC FATE: Vapor phase 2,5-dihydrothiophene 1,1-dioxide is degraded in the ambient atmosphere by reaction with photochemically formed hydroxyl radicalsthe half-life for this reaction in air can be estimated to be about 6.7 hrs(1,SRC). Vapor phase 2,5-dihydrothiophene 1,1-dioxide is also rapidly degraded by reaction with ozone in the tropospherethe half-life for this reaction in air can be estimated to be about 1.4 hrs(1,SRC). |

| Soil Adsorption/Mobility | Based on an estimated log Kow of -1.448(2) the Koc for 2,5-dihydrothiophene 1,1-dioxide can be estimated to be about 4 using a recommended regression derived equation(1,SRC). This Koc value suggests that 2,5-dihydrothiophene 1,1-dioxide will have very high mobility in soil and will leach(3). |
| Artificial Pollution Sources | 2,5-Dihydrothiophene 1,1-dioxide is used as a specialty solvent in petroleum refining and during the manufacture of sulfolane which is also a solvent in petroleum refining(1)it may be released to the environment in waste streams from its production and use(SRC). |

| Environmental Bioconcentration | Based on an estimated log Kow of -1.448(2) the BCF for 2,5-dihydrothiophene 1,1-dioxide can be estimated to be 4.7 using a recommended regression derived equation(1,SRC). This BCF value suggests that 2,5-dihydrothiophene 1,1-dioxide would not bioconcentrate in aquatic organisms(SRC). |
| Volatilization from Water/Soil | The Henry's Law constant for 2,5-dihydrothiophene 1,1-dioxide can be estimated to be 4.3X10-6 atm-cu m/mole at 25 °C using a chemical structure estimation method(1). This value of Henry's Law constant suggests that 2,5-dihydrothiophene 1,1-dioxide may slowly volatilize from water(2). Based on this Henry's Law constant value, the volatilization half-life of 2,5-dihydrothiophene 1,1-dioxide from a model river 1 m deep flowing 1 m/sec with a wind velocity of 3 m/sec has been estimated to be approximately 225 days(2,SRC). |
| Non-Human Toxicity Excerpts | 3-Sulfolene was tested for mutagenicity in the Salmonella/microsome preincubation assay using a protocol approved by the National Toxicology Program. 3-Sulfolene was tested over a wide range of doses (0, 100, 333, 1000, 3333, and 10,000 ug/plate) in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of Aroclor-induced rat or hamster liver S9. 3-Sulfolene was negative in these tests and the highest ineffective dose level tested in any Salmonella tester strain was 10,000 ug/plate. |
| Environmental Abiotic Degradation | The rate constant for the vapor-phase reaction of 2,5-dihydrothiophene 1,1-dioxide with photochemically produced hydroxyl radicals can be estimated to be 5.74X10-11 cu cm/molecule-sec at 25 °C which corresponds to an atmospheric half-life of about 6.7 hrs at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of 2,5-dihydrothiophene 1,1-dioxide with ozone in the troposphere can be estimated to be 2X10-16 cu cm/molecule-sec at 25 °C which corresponds to a half-life of about 1.4 hrs at an atmospheric concn of 7X10+11 molecules per cu cm(1-2,SRC). |
| Probable Routes of Human Exposure | 2,5-Dihydrothiophene 1,1-dioxide is used as a specialty solvent in petroleum refining and during the manufacture of sulfolane which is also a solvent in petroleum refining(1). In occupational settings, workers may be exposed to 2,5-dihydrothiophene 1,1-dioxide by inhalation of vapors and through eye and skin contact(SRC). |
| Environmental Fate/Exposure Summary | 2,5-Dihydrothiophene 1,1-dioxide may be released to the environment in waste streams from oil refineries during its production and use. If released to soil, 2,5-dihydrothiophene 1,1-dioxide is expected to leach (estimated Koc of 4). No data were located which suggest biodegradation is an important fate process of 2,5-dihydrothiophene 1,1-dioxide in soil or water. If released to water, adsorption to sediment and bioconcentration in aquatic organisms are not expected to be environmentally important removal processes of 2,5-dihydrothiophene 1,1-dioxide. A volatilization half-life of 225 days has been estimated for a model river (one meter deep). If released to the atmosphere, vapor-phase 2,5-dihydrothiophene 1,1-dioxide is expected to degrade by reaction with photochemically produced hydroxyl radicals (estimated half-life of 6.7 hrs). Vapor phase 2,5-dihydrothiophene 1,1-dioxide may also be rapidly degraded by reaction with ozone in the tropospherethe half-life for this reaction in air can be estimated to be about 1.4 hrs. In occupational settings, exposure to 2,5-dihydrothiophene 1,1-dioxide may occur through inhalation of vapors and through eye and skin contact. (SRC) |
