反応性グループNitro, Nitroso, Nitrate, and Nitrite Compounds, Organic
Special Reports2-Nitro-p-phenylenediamine. a component of both semipermanent and permanent hair dye formulations, was selected for bioassay by the National Cancer Institute because of the increased incidence of bladder cancer among dye manufacturing industry workers. Aromatic amines are one of several classes of organic chemicals thought to contribute to the increased cancer risk in this industry. The widespread exposure to 2-nitro-p-phenylenediamine among the general population, and the possibility of an increased cancer risk among hairdressers were additional factors in the selection of this compound for testing. A bioassay for the possible carcinogenicity of 2-nitro-p-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. ... Under the conditions of this bioassay, dietary administration of 2-nitro-p-phenylenediamine was carcinogenic to female B6C3F1 mice, causing an increased incidence of hepatocellular neoplasms, primarily hepatocellular adenomas. There was no convincing evidence for the carcinogenicity of the compound in Fischer 344 rats or in male B6C3F1 mice.[DHEW/NCIBioassay of 2-Nitro-p-phenylenediamine for Possible Carcinogenicity (1979) Technical Rpt Series No. 169 DHEW Pub No. (NIH) 79-1725]A safety assessment of 2-nitro-p-phenylenediamine and 4-nitro-o-phenylenediamine was published in 1985 with the conclusion "for those persons not sensitized, the Expert Panel Concludes that 2-nitro-p-phenylenediamine and 4-nitro-o-phenylenediamine are safe as hair dye ingredients at the current concentration of use" ... Studies available since that safety assessment was completed, along with updated information regarding uses and use concentrations, were considered by the CIR Expert Panel. The Panel determined to not reopen this safety assessment.[Cosmetic Ingredient Review2-Nitro-p-Phenylenediamine and 4-Nitro-o-Phenylenediamine. JACT 4(3): 161-202, 1985Re-Review: International Journal of Toxicology. 25(S2), 2006]

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 46(SRC), determined from a log Kow of 0.53(2) and a regression-derived equation(3), indicates that 2-nitro-p-phenylenediamine is expected to have very high mobility in soil(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4), suggesting that mobility may be much lower in some soils(SRC). Volatilization of 2-nitro-p-phenylenediamine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 5.8X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(5). 2-Nitro-p-phenylenediamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.6X10-5 mm Hg(SRC), determined from a fragment constant method(6). Information is not available regarding the biodegradation potential of 2-nitro-p-phenylenediaminehowever, 80% percent of p-phenylenediamine was removed over 120 hours based on chemical oxygen demand measurements and using an activated sludge inoculum(7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 46(SRC), determined from a log Kow of 0.53(2) and a regression-derived equation(3), indicates that 2-nitro-p-phenylenediamine is not expected to adsorb to suspended solids and sediment(SRC). 2-Nitro-p-phenylenediamine may bind strongly to organic matter as aromatic amines are highly reactive with an affinity for organic materials(4). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 5.8X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 2-Nitro-p-phenylenediamine absorbs at a wavelength of 441 nm(8) and therefore may be susceptible to direct photolysis by sunlight(SRC). Information is not available regarding the biodegradation potential of 2-nitro-p-phenylenediaminehowever, 80% percent of p-phenylenediamine was removed over 120 hours based on chemical oxygen demand measurements and using an activated sludge inoculum(9).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-nitro-p-phenylenediamine, which has an estimated vapor pressure of 5.6X10-5 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2-nitro-p-phenylenediamine 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 17 hours(SRC), calculated from its rate constant of 2.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase 2-nitro-p-phenylenediamine may be removed from the air by wet or dry deposition(SRC). 2-Nitro-p-phenylenediamine absorbs at wavelengths of 441 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).

Medical SurveillanceRoutine checking of lips, tongue and nail beds of exposed personnel for signs of cyanosis. /Protect/ from exposure those individuals with anemia, cardiovascular or pulmonary diseases.
Soil Adsorption/MobilityThe Koc of 2-nitro-p-phenylenediamine is estimated as 46(SRC), using a log Kow of 0.53(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-nitro-p-phenylenediamine is expected to have very high mobility in soil. However, anilines (aromatic amines) are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4), suggesting that mobility may be much lower in some soils(SRC).
Natural Pollution Sources...is not known to occur as natural product.
Human Toxicity Excerpts/HUMAN EXPOSURE STUDIES/ Thirty-nine hairdressers were patch tested for 24 hours with 2-nitro-p-phenylenediamine (2NPPD). Thirty-two of the hairdressers had no history of allergic contact dermatitis from p-phenylenediamine, and none of these 32 had a positive reaction to 2NPPD. One of seven hairdressers who had experienced strongly positive reactions to p-phenylenediamine was positive for 2NPPD. The researchers suggested that this may have been a cross reaction./CASE REPORTS/ A case has been described in the literature in which a dental hygienist developed dermatitis on the skin of her left forearm where it came into frequent contact with the hair of patients. A patch test with p-phenylenediamine mix was negative at 48 and 96 hours, and, with 2% 2-nitro-p-phenylenediamine, was strongly positive at 48 hours./GENOTOXICITY/ At 50-100 ug/mL, 2-nitro-p-phenylenediamine induced chromosome & chromatid gaps & breaks in human peripheral blood lymphocytes./GENOTOXICITY/ 2-Nitro-p-phenylenediamie... was active in inducing unscheduled DNA synthesis in HELA human cervical cancer cells.For more Human Toxicity Excerpts (Complete) data for 2-NITRO-P-PHENYLENEDIAMINE (6 total), please visit the HSDB record page.
