4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

In case of skin contact

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Inhalation or ingestion causes headache, nausea, methemo- globinemia, vomiting, weakness, and stupor; cyanosis caused by contact usually develops in 4-6 hrs.; prolonged and excessive exposure may also cause liver damage. Contact with eyes or skin causes irritation; continued exposure may cause same symptoms as inhalation or ingestion. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

INHALATION: Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN: Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. EYES: First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

12.2 Persistence and degradability

AEROBIC: In a 2 week closed bottle biodegradation test, using 100 mg/L substrate and 30 mg/L sludge, 2-nitroaniline had a theoretical BOD of 0%(1). Degradation in a soil mineral salts suspension took greater than 64 days as determined by 100% loss of UV absorbance(2). A 16% BOD threshold was measured with a Warburg respirometer using aniline-acclimated activated sludge(3). A 0% removal (based on chemical oxygen demand) was measured in a batch system using activated sludge and a 5-day incubation period(4). Biological degradation in an electrolytic respirometer using activated sludge was in excess of 10 days(5). 2-Nitroaniline was not biodegradable in an electrolytic respirometer study, although 4-nitroaniline was found to be biodegradable using the same test conditions(6). Aerobic incubation of 2-nitroaniline in a rotary shaker using sewage inocula for 52 days resulted in a maximum loss of 15% as measured by UV absorbance loss(7). A 20-day study using uniformly ring-labeled 2-nitroaniline had a 14-carbon dioxide evolution of 1.9%, measured from laboratory flask system containing a silt loam soil media(8); 14-carbon dioxide evolution was less than 0.3% from the same soil system which had been sterilized with sodium azide(8). 2-Nitroaniline had a biodegradation rate of 0.023/hr in river water giving a half-life of 31 hours, which was classified as poor degradation(9). A 5 day BOD at 20°C in Songhua river water was -5% for 2-nitroaniline(10).

12.3 Bioaccumulative potential

A 6 week bioconcentration study obtained BCF values of 2.1-4.9 and <10 for concentrations of 2- nitroaniline of 0.5 and 0.05 mg/L, respectively(1). An aquarium study using carp fish found 2-nitroaniline to have a low bioaccumulation potential(2). A study using zebrafish experimentally determined the BCF for 2-nitroaniline to be 8.1(3). According to a classification scheme(4), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The log Koc of 2-nitroaniline was measured as 1.77 giving a Koc of 59(1). According to a classification scheme(2), this Koc value suggests that 2-nitroaniline is expected to have high mobility in soil. 2-Nitroaniline was found to have a Kd value of 8.4 L/kg in homoionic K+ Montmorillonite type soil(3). However, anilines are expected to bind strongly to humus or organic matter in soils due to high reactivity of the aromatic amine group(4,5), suggesting that mobility may be much lower in some soils(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The 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 packaging

Containers 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.
