no data available
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 the 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: The percent losses of herbicidal effectiveness of 0.1-32 ppm of 2,3,6,-trichlorobenzoic acid in an aerobic grab sample test with 4 different soils were 15.9%, 3.2%, 6.2%, and 9.0% after 120 days in incubation in Staten Island peaty muck, Stockton adobe clay, Yolo fine sandy loam and Hesperia sandy loam, respectively(1). Leaching of the 2,3,6-trichlorobenzoic acid was ruled out as a mechanism of effectiveness reduction(1). Incubation for 80 days of test concentrations of 100 ppm using a soil perfusion system with Celeryville muck with high microbial activity resulted in only 2% degradation (as measured by chloride ion acclimation in the perfusate)(2). 2,3,6-Trichlorobenzoic acid, 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(3). No degradation of 100 ppm 2,3,6,-trichlorobenzoic acid was observed in 36 days incubation in aqueous laboratory aerobic sewage die-away screening tests using raw sewage inoculum(4). Addition of glucose or benzoate and m-chlorobenzoate to the sewage did not promote degradation of the 2,3,6-trichlorobenzoic acid(4).
Bioaccumulative potential
The BCF of 2,3,6-trichlorobenzoic acid was <0.4 at a concentration of 293 ppb and <3.5 at a concentration of 29.3 ppb using carp (Cypinus carpio) which were exposed over a 6-week period(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2,3,6-trichlorobenzoic acid can be estimated to be 65(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,3,6-trichlorobenzoic acid is expected to have high mobility in soil(SRC). The estimated pKa of 2,3,6-trichlorobenzoic acid is 1.8(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). 2,3,6-Trichlorobenzoic acid readily leaches through soil; 2,3,6-trichlorobenzoic acid has been found at depths of 11 feet following surface application(5). Approximately 10% of the 2,3,6-trichlorobenzoic acid applied at rates of 0.2 and 0.6 kg/hectare to 8 experimental plots leached an unspecified distance to the tile-drain groundwater in 3 months(6). 2,3,6-Trichlorobenzoic acid was found to be readily leached from soil columns containing 4 different types of soil (Staten Island peaty muck, Stockton adobe clay, Yolo fine sandy loam and Hesperia sandy loam)(7). In a soil column filled with silty clay loam, 2,3,6-trichlorobenzoic acid was leached 20 inches upon the addition of sufficient water to wet the column to 22 inches(8). Most of the residual herbicidal activity of 2,3,6-trichlorobenzoic acid applied to a test field at a rate of 15-30 lb/acre was present in the second, third and fourth foot depth of the 6 foot of depth tested(9).
Other adverse effects

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.
