Most important symptoms/effects, acute and delayed
Benzonitrile may enter the human body by ingestion, absorption through the skin, or inhalation. The earliest symptoms of cyano compound intoxication may be weakness, headaches, confusion, and occasionally nausea and vomiting. The respiratory rate and depth will usually be increased at the beginning and at later stages become slow and gasping. Blood pressure is usually normal, especially in the mild or moderately severe cases, although the pulse rate is usually more rapid than normal. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
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 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. Cyanide and related compounds

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces toxic fumes including hydrogen cyanide and nitrogen oxides. Reacts violently with strong acids. This produces highly toxic hydrogen cyanide. Attacks some plastics.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Combustible but burns with difficulty.The cyano group can be readily hydrolyzed in the presence of mineral acids to produce stable, moderately toxic benzoic acid . When heated to decomposition, it emits highly toxic fumes of nitrogen oxides and hydrogen cyanide [Sax, 9th ed., 1996, p. 353].
Conditions to avoid
no data available
Incompatible materials
Strong acids which can liberate hydrogen cyanide. Forms explosive mixture with air.

Persistence and degradability
AEROBIC: Benzonitrile , present at 100 mg/L, reached 63.4% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Other screening studies give similar results (63.4-80.8%) and benzonitrile is confirmed to be biodegradable according to the standard test of the Japanese Ministry of Industry and Trade (MITI) that employs a mixed inoculum obtained from freshwater, soil, and sludge(2-4). The theoretical oxygen demand (ThOD) for benzonitrile in Ohio River Water from Cincinnati and/or aged sewage sludge were 0, 60, 90% and/or 0, 40, 80% after 2, 5, and 12 days, respectively(5). The BOD for benzonitrile in a bench-scale activated sludge unit was measured to be 93-98%(6). The BOD for benzonitrile in river water, present at 50 ppm, was 7%(7). Benzonitrile achieved 100% degradation after 280 minutes in a phosphate buffer solution in the soil and after 500 minutes in a soil slurry(8). Benzonitrile also achieved 20% and 44% in ash and ash-amended soil slurries at 2000 minutes, respectively(8). Benzonitrile achieved 88% degradation after 8, 10, and 12.5 hours in char-amended soil, soil and washed-char-amended soil slurries(9).
Bioaccumulative potential
An estimated BCF of 5 was calculated in fish for benzonitrile(SRC), using a measured log Kow of 1.56(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of benzonitrile is estimated as 150(SRC), using a log Kow of 1.56(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that benzonitrile is expected to have moderate mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
