| 대기 기준 | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Sulfanilic acid is produced, as an intermediate or a final product, by process units covered under this subpart. |

| 상호 작용 | WHEN GIVEN ORALLY IN SUFFICIENT AMT (100-500 MG/KG IN RATS), THE CHELATOR /ETHYLENE DIAMINETETRAACETATE/ INCREASES THE RATES OF ABSORPTION OF HEPARIN.../&/ SULFANILIC ACID...ALL LIPID-INSOL SUBSTANCES WHICH ORDINARILY ARE POORLY ABSORBED FROM GI TRACT.BILE SALTS, DISODIUM EDTA, TETRACYCLINE, OR SODIUM LAURYL SULFATE PRESENT IN THE GUT LUMEN OF THE RAT INCREASED THE TRANSFER OF SULFANILIC ACID FROM THE SMALL INTESTINE TO THE THORACIC DUCT LYMPH.The effect of mitomycin C (MMC) pre-administration intravenously on the absorption of drugs from rat stomach has been examined by means of the in-situ loop technique. 48 hr after the MMC-treatment, the absorption of salicylic acid, aspirin and sulphanilic acid was not influenced but that of sulphanilamide was significantly increased compared with the control. At 96 hr, a differential effect of MMC on the absorption of each drug was seen: the absorption of weakly acidic drugs was significantly decreased while that of bases and strong sulphonic acid increased. The decreased absorption of salicylic acid and aspirin correlated with the reduced gastric mucosal blood flow. At 96 hr there were severe hemorrhagic lesions in the gastric mucosa. The increase in absorption of poorly absorbed drugs could be ascribed to the increased permeability of the blood-gastric epithelium barrier as was evidenced by leakage of Evans Blue. |

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that sulfanilic acid is expected to have very high mobility in soil(SRC). The pKa of sulfanilic acid is 3.25 at 25 °C(3), indicating that this compound will partially exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of sulfanilic acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 8.9X10-13 atm-cu m/mole(SRC), using a fragment constant estimation method(2). Sulfanilic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1X10-9 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Based on results of the majority of eight separate laboratory determinations, it can be concluded that sulfanilic acid is not readily biodegradable(5). Sulfanilic acid, present at 100 mg/L, reached 8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5) which also indicates the compound is not readily biodegradable(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that sulfanilic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 8.9X10-13 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). According to a classification scheme(4), an estimated BCF of 3(SRC), from a log Kow of -2.16(5) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Sulfanilic acid absorbs UV light at wavelengths >290 nm(6) and may be susceptible to direct photolysis in sunlit water(SRC). Based on results of the majority of eight separate laboratory determinations, it can be concluded that sulfanilic acid is not readily biodegradable(7). Sulfanilic acid, present at 100 mg/L, reached 8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(8) which also indicates the compound is not readily biodegradable(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), sulfanilic acid, which has an estimated vapor pressure of 1X10-9 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase sulfanilic acid may be removed from the air by wet or dry deposition(SRC). Sulfanilic acid absorbs UV light at wavelengths >290 nm(3), and therefore may be susceptible to direct photolysis by sunlight(SRC). |

| Environmental Biodegradation | AEROBIC: In a study assessing biodegradability by manometric respirometry conducted by the Commission of European Communities, five of the eight laboratories employed in the study determined sulfanilic acid was <20% biodegradable(1). A sixth laboratory where the inoculum was adapted to sulphonic acids found sulfanilic acid to be 70% biodegradable at 10 days and 90% biodegradable at 28 days(1). A seventh laboratory found duplicates on one occasion to give no removal while a single determination yielded 12% degradation(1). The eighth laboratory reported 6, 14 and 62% biodegradation after 28 days in three(1). Based on results of the majority of eight separate laboratory determinations, it can be concluded that sulfanilic acid is not readily biodegradable(1). Sulfanilic acid, present at 100 mg/L, reached 8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(2) which also indicates the compound is not readily biodegradable(SRC). |

| Environmental Bioconcentration | An estimated BCF of 3 was calculated in fish for sulfanilic acid(SRC), using a log Kow of -2.16(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). |
|---|
| Volatilization from Water/Soil | The Henry's Law constant for sulfanilic acid is estimated as 8.9X10-13 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that sulfanilic acid is expected to be essentially nonvolatile from water surfaces(2). Sulfanilic acid's Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). Sulfanilic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1X10-9 mm Hg at 25 °C(SRC), determined from a fragment constant method(1). |
