| Entsorgungsverfahren | 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. |
| Preventive Measures | 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. |
| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 840(SRC), determined from a structure estimation method(2), indicates that m-chlorostyrene is expected to have low mobility in soil(SRC). Volatilization of m-chlorostyrene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.1X10-3 atm-cu m/mole(SRC), using a fragment constant estimation method(3). The potential for volatilization of m-chlorostyrene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 0.98 mm Hg(4).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 840(SRC), determined from a structure estimation method(2), indicates that m-chlorostyrene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a estimated Henry's Law constant of 2.1X10-3 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 2 hrs and 5 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 100(SRC), from an estimated log Kow of 3.54(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), m-chlorostyrene, which has a vapor pressure of 0.98 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase m-chlorostyrene 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 14 and 13 hrs, respectively(SRC), calculated from rate constants of 2.8X10-11 and 2.1X10-17 cu cm/molecule-sec, respectively at 25 °C(SRC) derived using a structure estimation method(3). |
| Unerwünschte Wirkungen | Neurotoxin - Acute solvent syndrome |
| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc for m-chlorostyrene can be estimated to be 840(SRC). According to a classification scheme(2), this estimated Koc value suggests that m-chlorostyrene is expected to have low mobility in soil(SRC). |
| Human Toxicity Excerpts | A skin & eye irritant. /Chlorostyrene/ |
| Environmental Biodegradation | Data regarding the biodegradation of m-chlorostyrene in either soil or aquatic systems were not available. (SRC) |
| Environmental Bioconcentration | An estimated BCF of 100 was calculated for m-chlorostyrene(SRC), using an estimated log Kow of 3.54(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). |
| Volatilization from Water/Soil | The Henry's Law constant for m-chlorostyrene is estimated as 2.1X10-3 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that m-chlorostyrene 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 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)(2) is estimated as 5 days(SRC). m-Chlorostyrene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of m-chlorostyrene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 0.98 mm Hg(3). |
| Environmental Abiotic Degradation | The rate constant for the vapor-phase reaction of m-chlorostyrene with photochemically-produced hydroxyl radicals has been estimated as 2.8X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 14 hrs at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of m-chlorostyrene with ozone has been estimated as 2.1X10-17 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 13 hrs at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). m-Chlorostyrene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). |
| Probable Routes of Human Exposure | Occupational exposure to m-chlorostyrene may occur through inhalation and dermal contact with this compound at workplaces where m-chlorostyrene is produced or used. (SRC) |
| Environmental Fate/Exposure Summary | Information regarding the production and use of m-chlorostyrene was not available. If released to air, a vapor pressure of 0.98 mm Hg at 25 °C indicates m-chlorostyrene will exist solely as a vapor in the ambient atmosphere. Vapor-phase m-chlorostyrene will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozonethe half-lives for these reactions in air are estimated to be 14 and 13 hrs, respectively. If released to soil, m-chlorostyrene is expected to have low mobility based upon an estimated Koc of 840. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 2.1X10-3 atm-cu m/mole. m-Chlorostyrene may volatilize from dry soil surfaces based upon its vapor pressure. If released into water, m-chlorostyrene 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 2 hrs and 5 days, respectively. An estimated BCF of 100 suggests the potential for bioconcentration in aquatic organisms is moderate. Hydrolysis is not expected to occur due to the lack of hydrolyzable functional groups. Occupational exposure to m-chlorostyrene may occur through inhalation and dermal contact with this compound at workplaces where m-chlorostyrene is produced or used. (SRC) |
