Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, mucous membranes and upper respiratory tract. Depending on the intensity and duration of exposure, effects may vary from mild irritation to severe destruction of tissue. Prolonged contact can cause eye damage. It can also cause irritation of the nose and throat. Exposure to this type of compound 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 type of compound 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 is highly toxic by inhalation, ingestion and 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 destruction of tissue. It is also an irritant of the nose and throat. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and hydrogen chloride gas. (NTP, 1992)

Persistence and degradability

31% biodegradation of 2,3,4,5-tetrachlorophenol was reported in an aerobic clay loam soil after 160 days(1). No significant degradation of 2,3,4,5-tetrachlorophenol was reported in an 80 day period in an anaerobic clay loam soil(1). In a river die-away study, 2,3,4,5-tetrachlorophenol had a biodegradation rate constant of 1.4X10-7 M/hr; a lag phase of 400 hours was reported(2). Groundwater containing 2,3,4,5-tetrachlorophenol at an average concn of 140 ug/l was present at 0.04 ug/l in the effluent of a sewage (activated sludge with phosphorus precipitation) treatment plant; dewatered sludge contained this compound at 0.07 mg/kg total solids(3). Half-lives of 2,3,4,5-tetrachlorophenol were reported as 7 (lag phase of 2 days) and 21 (lag phase of 12.5 days) days under aerobic and anaerobic conditions, respectively(4). A first-order biodegradation rate constant of 0.107/day (half-life of 6.5 days) was reported for 2,3,4,5-tetrachlorophenol in anaerobic estuarine sediment(5). Intermediates formed during this reaction are as follows: 3,4,5-trichlorophenol (27%), 2,4,5-trichlorophenol (22%), 2,3,5-trichlorophenol (3%), and 2,3,4-trichlorophenol (5%); 3,4-dichlorophenol>3,5-dichlorophenol>2,4/2,5-dichlorophenol; 3/4-chlorophenol(5). 94.9, 96.5, and 64.9% removal efficiency was reported for 2,3,4,5-tetrachlorophenol initially present at 0.37, 1.20, and 2.21 umol/l, respectively, following treatment in an upflow anaerobic sludge blanket reactor(6).

Bioaccumulative potential

An estimated BCF of 930 was calculated for 2,3,4,5-tetrachlorophenol(SRC), using a log Kow value of 4.21(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). BCF values of 38 to 41 and 213 to 351 were measured in two species of earthworms, E. fetida andrei and L. rubellus, respectively(4). Leeches exposed to water in Thunder Bay Harbor, Lake Superior, Canada for 3 weeks bioaccumulated 2,3,4,5-tetrachlorophenol at 63 to 427 ng/g near wastewater discharge points from a pulp mill; at sites located at a greater distance from the discharge area no bioaccumulation in leeches was seen(5).

Mobility in soil

The Koc of 2,3,4,5-tetrachlorophenol is estimated as approximately 4600(SRC), using a log Kow value of 4.21(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that 2,3,4,5-tetrachlorophenol is expected to have slight mobility in soil(SRC). Koc values of 13200, 13900, and 12500 were measured for a lake sediment (foc=0.094), river sediment (foc=0.026), and aquifer material (foc=0.0084), respectively(7). A Kp value of 0.94 was measured for 2,3,4,5-tetrachlorophenol in aquifer sand at a pH value of 2(4). 2,3,4,5-Tetrachlorophenol added to Eustis fine sand (0.23-0.39% organic carbon; 96.4% sand) had a measured Kp value of 4.19 mL/g; 47% of this compound was ionized in this experiment(6). In addition, a desorption rate coefficient of 2.07 per hour was measured(6). In an aqueous adsorption study, 1360 pg/g 2,3,4,5-tetrachlorophenol was found in the sediment, 480 pg/g in suspended matter, and 2 pg/g in the water; the sediment to water ratio is 680 and suspended matter to water ratio is 240(5).

SECTION 13: Disposal considerations

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.
