Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include severe irritation and burns of the skin and eyes; irritation of the respiratory tract, dizziness, stomach pain, exhaustion, coma and damage to the liver or kidneys. Other symptoms include headache, nausea and vomiting. It may cause corrosion of the tissues of the mucous membranes and upper respiratory tract, eyes and skin. Inhalation may result in burning sensation, coughing, wheezing, laryngitis and shortness of breath. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi; chemical pneumonitis and pulmonary edema. Symptoms of exposure to this class of compounds include skin sensitization, profuse sweating, painless blanching or erythema of the skin, intense thirst, diarrhea, cyanosis from methemoglobinemia, hyperactivity, stupor, blood pressure fall, hyperpnea, abdominal pain, hemolysis and convulsions. If death from respiratory failure is not immediate, jaundice and oliguria or anuria may occur. ACUTE/CHRONIC HAZARDS: This chemical is highly toxic by inhalation, ingestion or skin absorption. It is corrosive to tissue of the mucous membranes and upper respiratory tract, eyes and skin. When heated to decomposition it emits acrid smoke and toxic fumes of carbon monoxide and carbon dioxide. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Administer activated charcoal . Dilution may be contraindicated because it may increase absorption. Do not use emetics . Cover skin burns with dry sterile dressings after decontamination . Phenols and Related compounds

Persistence and degradability
Anaerobic degradation of phenolic compounds to methane and carbon dioxide in sewage sludge digestion occurred in both ground water and laboratory digestors. water samples were collected from the near surface ground water in an area contaminated with plant process wastes resulting from operation of a coal tar distilling and wood treating plant. phenolic compounds (including 2,5-dimethylphenol) were isolated from the aqueous samples by dichloromethane extraction.
Bioaccumulative potential
An estimated BCF of 35 was calculated for 2,5-dimethylphenol(SRC), using a log Kow of 2.33(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate.
Mobility in soil
The Koc of 2,5-dimethylphenol is estimated as 440(SRC), using a log Kow of 2.33(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,5-dimethylphenol is expected to have moderate mobility in soil(SRC).
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.
