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.

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 54(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that 4-chloro-3-nitrobenzenesulfonamide should have very high mobility in soil(SRC). Volatilization of 4-chloro-3-nitrobenzenesulfonamide should not be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 1.2X10-9 atm-cu m/mole(4,SRC), or from dry soil surfaces(SRC) based on an estimated vapor pressure of 1.8X10-6 mm Hg(5,SRC). Insufficient data are available to determine the rate or importance of biodegradation of 4-chloro-3-nitrobenzenesulfonamide in soil(SRC).

AQUATIC FATE: An estimated Koc value of 54(SRC), determined from an experimental log Kow(1) and a recommended regression-derived equation(2), indicates that 4-chloro-3-nitrobenzenesulfonamide should not adsorb to suspended solids and sediment(SRC) in the water(2,SRC). 4-Chloro-3-nitrobenzenesulfonamide would be essentially non-volatile from water surfaces based on an estimated Henry's Law constant of 1.2X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). An estimated BCF value of 1.9(2,SRC), from an experimental log Kow(1), suggests that 4-chloro-3-nitrobenzenesulfonamide will not bioconcentrate in aquatic organisms(SRC) according to a recommended classification scheme(4). Insufficient data are available to determine the rate or importance of biodegradation of 4-chloro-3-nitrobenzenesulfonamide in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 4-chloro-3-nitrobenzenesulfonamide, which has an estimated vapor pressure of 1.8X10-6 mm Hg at 25 °C(2,SRC) will exist as both a vapor and particulate in the ambient atmosphere. Vapor-phase 4-chloro-3-nitrobenzenesulfonamide is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 438 days(3,SRC). Particulate-phase 4-chloro-3-nitrobenzenesulfonamide may be physically removed from the air by wet and dry deposition(SRC).

The Koc of 4-chloro-3-nitrobenzenesulfonamide is estimated as approximately 54(SRC), using an experimental log Kow of 0.66(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 4-chloro-3-nitrobenzenesulfonamide should have very high mobility in soil(SRC).

An estimated BCF value of 1.9 was calculated for 4-chloro-3-nitrobenzenesulfonamide(SRC), using an experimental log Kow of 0.66(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will not be an important fate process(SRC).

The Henry's Law constant for 4-chloro-3-nitrobenzenesulfonamide is estimated as 1.2X10-9 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that 4-chloro-3-nitrobenzenesulfonamide will be essentially nonvolatile from water surfaces(2,SRC). 4-Chloro-3-nitrobenzenesulfonamide's vapor pressure, 1.8X10-6 mm Hg(3,SRC) and Henry's Law constant(1,SRC) indicate that volatilization from dry or moist soil should not occur(SRC).

The rate constant for the vapor-phase reaction of 4-chloro-3-nitrobenzenesulfonamide with photochemically produced hydroxyl radicals has been estimated as 3.8X10-14 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 438 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC).

4-Chloro-3-nitrobenzenesulfonamide's production and use as a dye intermediate may result in its release to the environment through various waste streams. If released to soil, 4-chloro-3-nitrobenzenesulfonamide should have very high mobility. Volatilization of 4-chloro-3-nitrobenzenesulfonamide should not be important from moist or dry soil surfaces. Insufficient data are available to determine the rate or importance of biodegradation of 4-chloro-3-nitrobenzenesulfonamide in soil or water. If released to water, 4-chloro-3-nitrobenzenesulfonamide should not adsorb to suspended solids and sediment. 4-Chloro-3-nitrobenzenesulfonamide would be essentially non-volatile from water surfaces. An estimated BCF value of 1.9 suggests that 4-chloro-3-nitrobenzenesulfonamide will not bioconcentrate in aquatic organisms. If released to the atmosphere, 4-chloro-3-nitrobenzenesulfonamide will exist as both a vapor and particulate. Vapor-phase 4-chloro-3-nitrobenzenesulfonamide is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals with an estimated half-life of about 438 days. Particulate-phase 4-chloro-3-nitrobenzenesulfonamide may be physically removed from the air by wet and dry deposition. (SRC)
