4.2 Most important symptoms/effects, acute and delayedSYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, mucous membranes and upper respiratory tract. Prolonged contact can cause damage to the eyes, severe irritation and burns. Exposure to this class of compounds may cause profuse sweating, intense thirst, abdominal pain, nausea, vomiting, diarrhea, cyanosis from methemoglobinemia, hyperactivity, stupor, blood pressure fall, hyperpnea, hemolysis, convulsions, collapse, coma and pulmonary edema followed by pneumonia. If death from respiratory failure is not immediate, jaundice and oliguria or anuria may occur. Other symptoms of exposure to this class of compounds may include headache, dizziness, rapid and difficult breathing, weakness, severe burns and internal damage. Chronic exposure may result in digestive disturbances, nervous disorders, skin eruptions and liver and kidney damage. Skin contact with this type of compound may result in softening and whitening of the skin, followed by the development of painful burns. Prolonged contact may lead to dermatitis. Local contact may also result in painless blanching or erythema and corrosion of the skin. Skin sensitivity reactions occur occasionally. ACUTE/CHRONIC HAZARDS: This compound may be harmful by inhalation, ingestion or skin absorption. It is an irritant of the skin, eyes, mucous membranes and upper respiratory tract; and prolonged contact may result in severe irritation or burns. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and hydrogen chloride gas. It is rapidly absorbed through the skin.
4.3 Indication of immediate medical attention and special treatment needed, if necessary/SRP:/ 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/

AEROBIC: 2,3-Dichlorophenol, 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 I test(1). 2,3-Dichlorophenol, present at 60 ppm in Wiggins, Mississippi acidic sandy loam with a pH of 4.8, reached 90% transformation to unspecified intermediates in 55 days, with a half-life of 28 days(2); 2,3-dichlorophenol, present at 130 ppm in Austin, Texas basic sandy silt loam with a pH of 7.8, reached 90% transformation to unspecified intermediates in 25 days, with a half-life of 8 days(2). Approximately 100% of initially added 2,3-dichlorophenol had been degraded after 2-4 weeks of incubation in four freshwater pond sediments(3); the chlorine at the 2-position was the most susceptible to the reductive dechlorination which occurred(3). After a lag period of approximately 2 weeks, 100% of the 2,3-dichlorophenol initially added to a freshwater pond sediment (which had been contaminated with asphalt) was observed to degrade within two weeks(3).
12.3 Bioaccumulative potentialA BCF of 7.5 to 35 was measured in fish for 2,3-dichlorophenol using carp (Cyprinus carpio) which were exposed over a six week period to a water concentration of 30 ppb, according to the standard test of the Japanese Ministry of Industry and Trade (MITI)(1). According to a classification scheme(2), this BCF suggest the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilAn average Koc of 426 has been measured in three types of lake and river sediments(1). According to a classification scheme(2), this Koc value suggests that 2,3-dichlorophenol is expected to have moderate mobility in soil. The pKa of 2,3-dichlorophenol is 7.7(3), indicating that this compound will partially exist 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).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
