Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound include painless blanching or erythema, vomiting, collapse, coma, profuse sweating, intense thirst, nausea, diarrhea, cyanosis, hyperactivity, stupor, blood pressure fall, hyperpnea, abdominal pain, hemolysis, convulsions and pulmonary edema followed by pneumonia. Other symptoms include irritation of the skin with redness and edema, eye irritation, corneal injury and iritis. The dusts cause irritation of the nose and pharynx. Exposure can cause irritation of the mucous membranes and respiratory tract, severe destruction of tissue (due to intensity and duration of exposure) and burns. Symptoms of exposure to a related compound include softening and whitening of the skin followed by development of painful burns, headache, dizziness, rapid and difficult breathing and weakness. Ingestion of a related compound causes severe burns and internal damage. Chronic exposure causes digestive disturbances, nervous disorders, skin eruptions, dermatitis, liver damage and kidney damage. ACUTE/CHRONIC HAZARDS: This compound may be harmful by inhalation or ingestion. It is an irritant of the skin, eyes, mucous membranes and upper respiratory tract. Prolonged contact may result in severe burns and destruction of tissue. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and hydrogen chloride gas. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
For advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or in respiratory arrest. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary . Start an IV with D5W TKO /SRP: To keep open, "minimal flow rate"/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema . For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors for hypotension with a normal fluid volume. Watch for signs of fluid overload . Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. . Treat seizures with diazepam (Valium). ... Use proparacaine hydrochloride to assist eye irrigation . Phenols and related compounds

Persistence and degradability
Pure cultures of the bacteria KC3 degraded 2,3,6-trichlorophenol under aerobic conditions(1). An actinomycete, Rhodococcus chlorophenolious has been shown to metabolize 2,3,6-trichlorophenol(2). The aerobic biodegradation half-life of 2,3,6-trichlorophenol in a mixed bacterial culture was 25 days, with a lag time of about 23 days(3). 2,3,6-Trichlorophenol (8 uM) was completely degraded in an anaerobic batch reactor over a 6 day incubation period(4).
Bioaccumulative potential
A BCF value of 400 was calculated for 2,3,6-trichlorophenol(SRC), using a log Kow of 3.77(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
Based on a pKa of 5.8(1), 2,3,6-trichlorophenol is expected to dissociate significantly in moist soil surfaces. Based on a recommended classification scheme(2), a Koc value of 2,700(SRC), determined from a log Kow of 3.77(3) and a recommended regression-derived equation(4), indicates that 2,3,6-trichlorophenol is expected to have slight mobility in soil, but the mobility of the anion is expected to be greater than that of the neutral species(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.
