4.2 Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this compound include pigmentation, skin irritation and inflammation; dermatitis, nausea, vomiting, abdominal pain, headache, vertigo, dizziness, faintness, cyanosis, collapse, difficulty breathing, convulsions, erythema, vesiculation, blistering, ulceration, gangrene, kidney and liver damage; chronic lung disease, hypothermia and coma. Other symptoms include sensation of burning and itching; conjunctivitis with mild hyperemia, photophobia and discharge; and keratoconjunctivitis, involving loss of corneal epithelium, clouding of the cornea, long-lasting irritability, miosis and photophobia. This compound may also cause salivation, respiratory difficulties, thready pulse, loss of pupillary reflexes, keratitis and corneal abrasion. ACUTE/CHRONIC HAZARDS: This compound is irritating to the skin and eyes. (NTP, 1992)

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin and eyes, muscular weakness, cardiovascular collapse and paralysis of the vasomotor centers. Ingestion produces burning in the mouth and throat, gastrointestinal distress, tremors and collapse. ACUTE/CHRONIC HAZARDS: This compound is an irritant and is easily absorbed through the skin. When heated to decomposition it emits toxic fumes. (NTP, 1992)

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 if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the 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. Poisons A and B

SECTION 10: Stability and reactivity

10.1 Reactivity

On combustion, forms toxic fumes.

10.2 Chemical stability

Darkens on exposure to air and light

10.3 Possibility of hazardous reactions

This material is combustible when exposed to heat or flame.Phenols, such as CREOSOTE, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. This compound is incompatible with acacia, albumin, oxidizers and cupric, ferric, gold and silver salts. (NTP, 1992)

SECTION 12: Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 230 µmol/L - 96 h.
  • Toxicity to daphnia and other aquatic invertebrates: IC50 - Daphnia magna - 63 mg/L - 24 h.
  • Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - > 100 mg/L - 72 h.
  • Toxicity to microorganisms: EC50 - Shk1 cells - 583 mg/L - 5 min.

12.2 Persistence and degradability

AEROBIC: o-Methoxyphenol, present at 100 mg/L, reached 97% of its theoretical BOD in four weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for o-methoxyphenol(SRC), using log Kow of 1.32(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

A log Koc of 1.60 for o-methoxyphenol, corresponding to a Koc of 40(SRC), was experimentally determined in a Brookston clay loam soil(1). A log Koc of 1.56(2), corresponding to a Koc of 36(SRC) has also been reported. According to a classification scheme(3), these Koc values suggest that o-methoxyphenol is expected to have very high mobility in soil. The pKa of o-methoxyphenol is 9.98(4), indicating that this compound will exist primarily in the undissociated form in the environment(SRC). The adsorption of the phenol occurrs by hydrogen bonding to sites on soil surfaces; ortho-substitution generally results in decreased adsorption compared to para-substitution due to steric hindrance(1).

12.5 Other adverse effects

no data available

SECTION 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.
