Most important symptoms/effects, acute and delayed
SYMPTOMS: This compound may cause severe irritation. High concentrations are extremely destructive to tissues of the mucous membranes and upper respiratory tract, skin and eyes. The greatest danger from ingestion of large quantities of this compound (2 g/kg) is intestinal obstruction. Aspiration or inhalation could cause chemical pneumonitis. Implantation will cause a foreign body reaction. A case of contact sensitivity has been reported. ACUTE/CHRONIC HAZARDS: This compound is a severe irritant. It is harmful if swallowed or inhaled. High concentrations are extremely destructive to tissues of the mucous membranes and upper respiratory tract, skin and eyes. When heated to decomposition, this compound may emit toxic fumes of carbon monoxide and carbon dioxide. It may produce aldehydes. It may also emit acrid smoke and irritating fumes. (NTP, 1992)
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 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. Poisons A and B

Persistence and degradability
AEROBIC: Sorbic acid is readily degradable in soil(1). Sorbic acid also shows high degradability, 95% within 6 days, in the Zahn-Wellens test(1). 100% degradation of sorbic acid was observed after 3 days incubation in seawater taken from Akashi Beach, Japan and river water taken from the Mino River, Japan, using an initial sorbic acid concentration of 60 ppm(2). Sorbic acid, present at 100 mg/L, reached 83% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(3). Sorbic acid was observed to biodegrade in soil suspensions(4). Sorbic acid (at 2 mg/L) was found to be readily biodegradable in an aerobic BOD test using domestic activated sludge with a 7-day theoretical BOD of 65.5% and a 28-day theoretical BOD of 74.9%(4).
Bioaccumulative potential
An estimated BCF value of 3 was calculated in fish for sorbic acid(SRC), using a log Kow of 1.33(1) and a recommended 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 sorbic acid can be estimated to be 9(SRC). According to a classification scheme(2), this estimated Koc value suggests that sorbic acid is expected to have very high mobility in soil. A Koc of less than 1 was estimated for sorbic using an HPLC method(3). The pKa of sorbic acid is 4.76(4), indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
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.
