Following skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Following eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Following ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Most important symptoms and effects, both acute and delayed

no data available

Indication of any immediate medical attention and special treatment needed

Immediate 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 if 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. Aromatic hydrocarbons and related compounds

Persistence and degradability

AEROBIC: A Warburg respirometer study utilizing an activated sludge seed and 6 hr of incubation resulted in a 2,6-xylidine depletion of 33-37% at a concentration of 20 ppm(1). In a 6 week soil degradation study using (14)C-labelled 2,6-xylidine, 8.4% of applied radioactivity was recovered via CO2 evolution in non-autoclaved soil while 0% CO2 evolution occurred in autoclaved soil(2). In a soil degradation study conducted in glass vessels using Chernozem soil, 2,6-xylidine (at 500 mg/L) was degraded after 3 days of incubation with >90% recovered in transformation products(3). Using OECD Guideline 301F (Ready Biodegradability: Manometric Respirometry Test), 2,6-xylidine (at 100 mg/L) reached 4, 8, 25, 38 and 69% of its theoretical BOD after 7, 13, 36, 42 and 70 days. respectively(4); these results indicated that 2,6-xylidine was not readily biodegradable according to OECD criteria, however, it is biodegradable after extended adaptation(4). In another OECD Guideline 301F study, 2,6-xylidine (at 100 mg/L) showed no bidegradation after 33 day(4). Using OECD Guideline 302B (Inherent biodegradability: Zahn-Wellens/EMPA Test) and an industrial activated sludge seed, 83% of initial 2,6-xylidine was removed from the aqueous test system after 11 days, however, the substance was mainly removed via volatilization(4). 2,6-Xylidine, 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(5).

Bioaccumulative potential

An estimated BCF value of 8 was calculated for 2,6-xylidine in fish(SRC), using a log Kow of 1.84(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2,6-xylidine can be estimated to be 190(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,6-xylidine is expected to have moderate mobility in soil. Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(3,4), suggesting that mobility may be lower in some soils(SRC). In a short term soil adsorption study using 14C-labelled 2,6-xylidine, 66% of the applied radioactivity was bound to the soil (3.4% organic matter, 36.6% sand, 28.2% silt, 35.2% clay) after 24 hrs(3).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
