In case of eye contactRinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
If swallowedRinse mouth. Refer immediately for medical attention.
4.2 Most important symptoms/effects, acute and delayedAbsorption of toxic quantities by any route causes cyanosis (blue discoloration of lips, nails, skin); nausea, vomiting, and coma may follow. Repeated inhalation of low concentrations may cause pallor, low-grade secondary anemia, fatigability, and loss of appetite. Contact with eyes causes irritation. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aniline and related compounds/

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsFlammable when exposed to heat, flame, or oxidizers.As a result of flow, agitation, etc., electrostatic charges can be generated.P-TOLUIDINE neutralizes acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Can react vigorously with oxidizing reagents. Emits very toxic fumes of oxides of nitrogen when heated to decomposition. Hypergolic reaction with red fuming nitric acid [Kit and Evered, 1960, p. 239, 242].

AEROBIC: 4-Aminotoluene, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1), suggesting this compound is not expected to biodegrade rapidly. However, other screening studies(2-8) give contradictory results and show 4-aminotoluene to be readily biodegradable in the environment. Some test results are: 64% of theoretical BOD used in 5 days with a sewage seed(2); 64% of theoretical BOD in 8 days using an activated sludge inoculum acclimated to aniline(3); and 97.7% removal in 5 days with activated sludge(4). When 4-aminotoluene was incubated with sewage, 90 and 100% degradation occurred after 10 and 14 days, respectively(5). Complete degradation was obtained in 4 days with a soil inoculum(6). 500 ppm of 4-aminotoluene completely degraded after 9 days in a Chernozen soil, leaving degradation products that persisted for over 90 days(7). 4-Aminotoluene, present at 2 mg/L, reached 46% of its theoretical BOD in 5 days using water from the Songhua River in China as an inoculum(8).
12.3 Bioaccumulative potentialA BCF of <1.3 was measured for 4-aminotoluene, using orange-red killifish (Oryzias latipes) which were exposed over an 8-week period(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilThe mean Koc of 4-aminotoluene to 4 silt loam soils was 79 at a pH range of 6.1 to 7.5 where 4-aminotoluene is predominantly un-ionized(1). At lower pH, electrostatic forces should play a larger role. Three other soils had Koc values of 323, 496, and 508 where the pH was 4.0, 4.3, and 5.9, respectively(2). In this case appreciable concentrations of 4-aminotoluene would be present in both the neutral and protonated forms. The isotherms were linear and the adsorption constant was highly correlated with the clay content of the soil(2). The mean Koc of 4-aminotoluene in 3 soils (silt, silt loam, loam) was 141 over a pH range of 5.2 to 7.4(3). According to a classification scheme(4), these Koc values suggest that 4-aminotoluene is expected to have high to moderate mobility in soil. The pKa of 4-aminotoluene is 5.10(5), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(6). Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(7,8), suggesting that mobility may be much lower in some soils(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
