| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. If symptoms (such as redness or irritation) develop, immediately transport the victim to a hospital.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992) |

| Umweltverhalten | TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 68(SRC), determined from an estimated log Kow(2) and a recommended regression-derived equation(3), indicates that C.I. Pigment Yellow 12 will have high mobility in soil(SRC). As C.I. Pigment Yellow 12 may act as an ionic compound in the environment, volatilization of this compound will not be important from moist soil surfaces(4,SRC). Based on limited data, C.I. Pigment Yellow 12 is expected to be resistant to aerobic biodegradation in soil(SRC)in the MITI test this compound is resistant to biodegradation0 biodegradation occurred after a period of two weeks(5).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 68(SRC), determined from an estimated log Kow(2) and a recommended regression-derived equation(1), indicates that C.I. Pigment Yellow 12 will not adsorb to suspended solids and sediment in water(SRC). As C.I. Pigment Yellow 12 may act as an ionic compound, volatilization from water surfaces is not expected(3,SRC). According to a classification scheme(4), experimental BCF values ranging from 0.38 to 5.4(5,SRC), suggests that bioconcentration in aquatic organisms is low(SRC). Based on limited data, C.I. Pigment Yellow 12 is expected to be resistant to aerobic biodegradation in water(SRC). Using the MITI test, this compound is resistant to biodegradationATMOSPHERIC FATE: The ionic nature of C.I. pigment Yellow 12 in the environment makes this compound essentially non-volatile(1,SRC). |

| Soil Adsorption/Mobility | The Koc of C.I. Pigment Yellow 12 is estimated as approximately 67(SRC), using an estimated log Kow(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that C.I. Pigment Yellow 12 has high mobility in soil(SRC). However, the ionic nature of the pigment may slow down or prevent leaching(SRC). |
| TSCA Test Submissions | Acute oral toxicity was evaluated in 10 young adult Charles River-CD male rats administered single doses of C.I. pigment yellow 12 (2,2'-((3,3'-dichloro(1,1'-biphenyl)-4,4'-diyl)bis(azo))bis(3-oxo -N-phenylbutanamide)) as a suspension in peanut oil at a level of 11,000 mg/kg of body weight. Mortality was not observed in any animalan LD50 value of greater then 11,000 mg/kg body weight was reported. Clinical observations included yellow feces for a few days after dosing. Gross necropsy findings were not reported. |
| Human Toxicity Excerpts | ... An incr in color printed newspapers might be a new source of clinical allergy to azo dyes. Patch tests were performed in 32 patients with an established p-aminoazobenzene allergy using a series of important azo dyes used in offset printing ink (Pigment Yellow 12, Pigment Yellow 13, Pigment Red 53, Pigment Red 57), as well as with dye containing inks and specimens of color printed newspaper containing these azo dyes. In 25 out of the 32 patients (78%), positive patch tests were seen to textile azo dyes, in particular to Disperse Orange 3 (24 patients). In none of the 32 patients were reactions observed to the azo dyes used in printing ink, to the inks used or to the color printed paper specimens, indicating that these products were apparently not a cause of contact dermatitis in /this/ group of patients with azo dye sensitization. |
| Artificial Pollution Sources | C.I. Pigment Yellow 12's production and use as a pigment for lacquers, printing inks, plastics, and rubber(1) may result in its release to the environment through various waste streams(SRC). |

| Environmental Bioconcentration | When carp were exposed to 0.1 mg/l C.I. Pigment Yellow 12, the experimental BCF ranged from 0.38 to 3.2 over a period of 6 weeks. When carp were exposed to 0.01 mg/l C.I. Pigment Yellow 12, the experimental BCF ranged from 2.4 to 5.4 over a 6 week period(1). According to a classification scheme(2), these BCF values suggest that bioconcentration in aquatic organisms is low. |
