4.2 Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, nose, throat, mucous membranes and upper respiratory tract. Contact with the skin may result in redness, edema, dermatitis and chemical burns. Contact with the eyes may result in corneal injury and iritis. It may also cause lacrimation. Other symptoms may include an increase followed by a decrease in respiratory rate and urinary output, fever, increased bowel action, weakness of movement, collapse, convulsions, lung damage, liver damage and kidney damage. Additional symptoms caused by this type of compound include painless blanching or erythema of the skin, corrosion, profuse sweating, intense thirst, nausea and vomiting, diarrhea, cyanosis from methemoglobinemia, hyperactivity, hyperthermia, skin rashes (sometimes chloracne), neurological and immunological effects, stupor, blood pressure fall, hyperpnea, abdominal pain, hemolysis, coma, and pulmonary edema followed by pneumonia. Rapid death has been reported. If death from respiratory failure is not immediate, jaundice and oliguria or anuria may occur. Skin sensitivity reactions occur occasionally. Prolonged eye contact may cause eye damage. Depending on the intensity and duration of exposure, effects may include severe destruction of tissue. ACUTE/CHRONIC HAZARDS: This compound is harmful by ingestion, inhalation and skin absorption. It is an irritant of the skin, eyes, nose, throat, mucous membranes and upper respiratory tract. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and hydrogen chloride gas. It may also emit toxic fumes of chloride ion.
4.3 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. /Phenols and related compounds/

12.2 Persistence and degradability
AEROBIC: 2,4,6-Trichlorophenol biodegraded 100% in 10-14 days with an 8 day lag time in filtered water and in 8-10 days with a 2 day lag time in water with sediment(1). 2,4,6-Trichlorophenol is expected to biodegrade in aerobic soils with a biodegradation half-life of about 5 days(2). Total degradation of 2,4,6-trichlorophenol in Dunkirk silt loam took 5 days and in Mardin silt loam took 13 days(3). In Labisch soil, 2,4,6-trichlorophenol biodegraded 67% in 60 days(4). 2,4,6-Trichlorophenol was aerobically degraded 95% in 3 days and 27% in 80 days in non-sterile and sterile clay loam, respectively(5). Microbial degradation, volatilization, and photodecomposition were ruled out in the sterile soil indicating that other mechanisms contribute to degradation(5). Activated sludge made from soil resulted in 100% removal of 2,4,6-trichlorophenol in 3 days(6); sewage seed resulted in complete removal in 7 days(7); 39% removal by activated sludge in 14 days was reported(8). 2,4,6-Trichlorophenol was readily degraded in an aerobic microcosm using soils from the saturated zone(9). A 2,4-dichlorophenol-acclimated soil inoculum completely degraded an unspecified initial concentration of 2,4,6-trichlorophenol in 28 days(10). 2,4,6-Trichlorophenol, present at 1.5 mg/L, was completely degraded in 8 days using an inoculum derived from river sediment obtained near a petrochemical plant(11). The compound was 92% degraded in 30 days using an activated sludge inoculum(12). 2,4,6-Trichlorophenol, present at 100 mg/L, reached 82.5-89.3% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(13).
12.3 Bioaccumulative potential
BCFs of 250-310 were reported for Golden Orfe fish (1,2). BCFs of 87 and 676 were reported for flagfish (Jordanella floridae)(3). A BCF of 270 was also reported(4). According to a classification scheme(5), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high(SRC).
12.4 Mobility in soil
The Koc values of 2,4,6-trichlorophenol in soil at pH 6, 7 and 7.7 were measured as 2200, 600 and 150 respectively(1). Koc values of 1300 and 800 were determined in river and lake sediment at an unspecified pH(2). Koc values of 2000(3), 1050(4) and 1070(5) were also reported for 2,4,6-trichlorophenol. According to a classification scheme(6), these Koc values suggest that 2,4,6-trichlorophenol is expected to have moderate to slight mobility in soil. The pKa of 2,4,6-trichlorophenol is 6.23(7), indicating that this compound will exist partially 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(8).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 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.
