SYMPTOMS: Symptoms of exposure to this compound may include severe irritation of the skin and eyes, and skin sensitization. It can cause corrosion of tissues. Other symptoms may include burns, irritation of mucous membranes and upper respiratory tract, nausea, vomiting and headaches. Exposure may also cause central nervous system depression, hepatic lesions and pain to the eyes. Symptoms of exposure to a related compound include drying and cracking of the skin on contact, primary irritation to mucosal surfaces, fatigue, weakness, depression, unsteadiness, feeling of drunkenness, abnormal electroencephalograms and one case of toxic retrobulbar neuritis. Chronic exposure to a related compound has caused peripheral neuropathies (distal hypesthesia and decreased nerve conduction velocities). ACUTE/CHRONIC HAZARDS: This compound is corrosive and can cause burns. It may be toxic by ingestion, inhalation or skin absorption. It is absorbed slowly through the skin. It is an irritant and, when heated to decomposition, it emits acrid fumes and toxic fumes of carbon monoxide and carbon dioxide. (NTP, 1992)
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. Aromatic hydrocarbons and related compounds

Evaluation: There is inadequate evidence in humans for the carcinogenicity of styrene-7,8-oxide. There is sufficient evidence in experimental animals for the carcinogenicity of styrene-7,8-oxide. Overall evaluation: Styrene-7,8-oxide is probably carcinogenic to humans (Group 2A).
No information is available on the reproductive or developmental effects of styrene oxide in humans. Maternal toxicity and increased fetal mortality have been observed in rats and rabbits exposed to styrene oxide by inhalation. Maternal toxicity, increased preimplantation loss of fetuses, reduced fetal weight, and increased incidence of ossification defects were reported in rats. Maternal toxicity and increased frequency of resorptions were reported in rabbits.
The substance is irritating to the eyes and skin. The substance may cause effects on the central nervous system. Exposure could cause lowering of consciousness.
This substance is probably carcinogenic to humans.
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.
AEROBIC: Styrene-7,8-oxide, present at 100 mg/L, reached 80-82% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1); however, the test results might be for the hydrolysis product, styrene glycol(SRC).
An estimated BCF of 3.5 was calculated in fish for styrene-7,8-oxide(SRC), using a log Kow of 1.61(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). Hydrolytic half-lives of 0.17, 28 and 40.9 hours have been reported for styrene-7,8-oxide at pH 3, 7, and 9, respectively(4). Hydrolysis is likely to be a more important fate than bioconcentration in aquatic organisms, particularly in acidic waters(SRC).
The Koc of styrene-7,8-oxide is estimated as 53(SRC), using a water solubility of 3,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that styrene-7,8-oxide is expected to have very high mobility in soil. Hydrolytic half-lives of 0.17, 28 and 40.9 hours have been reported for styrene-7,8-oxide at pH 3, 7, and 9, respectively(4). Hydrolysis is likely to be a more important fate than transport through soils, particularly in acidic soils(SRC).

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.
