Following ingestion
Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Poisonous; may be fatal if inhaled, swallowed or absorbed through the skin. Contact with solid, vapor or solution can cause severe local damage to the skin and mucous membranes. Symptoms include discoloration, severe irritation, erythema, swelling, papules and vesicles. Necrosis may result from long exposure. The eyes may experience irritation, conjunctivitis, photophobia, lacrymation and burning sensations. The cornea may suffer ulceration and scarring. Chronic eye exposure causes gradual brownish discoloration of the conjunctiva and cornea, small corneal opacities and damage in corneal structure which cause loss of visual acuity. (USCG, 1999)

SECTION 11: Toxicological information
Acute toxicity
- Oral: LD50 - 130 mg/kg bw.
- Inhalation: no data available
- Dermal: no data available
Skin corrosion/irritation
no data available
Serious eye damage/irritation
no data available
Respiratory or skin sensitization
no data available
Germ cell mutagenicity
no data available
Carcinogenicity
Evaluation: No epidemiological data relevant to the carcinogenicity of 1,4-benzoquinone were available. There is inadequate evidence in experimental animals for the carcinogenicity of 1,4-benzoquinone. Overall evaluation: 1,4-Benzoquinone is not classifiable as to its carcinogenicity to humans (Group 3).
Reproductive toxicity
No information is available on the reproductive or developmental effects of quinone in humans or animals.
STOT-single exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the eyes. Exposure far above the OEL could cause respiratory failure and death.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the skin and eyes. This may result in discolouration, inflammation and injury of the corneal epithelium.
Aspiration hazard
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 - Pimephales promelas - 0.045 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
Fourteen strains of phenol-utilizing bacteria isolated from soil did not visibly grow when using 1,4-benzoquinone as a carbon source in an aqueous mineral salts media over 5 days of incubation(1).
12.3 Bioaccumulative potential
An estimated BCF value of 0.84 was calculated for 1,4-benzoquinone(SRC), using an experimental log Kow value of 0.20(1) and a recommended regression derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will not be an important fate process(SRC).
12.4 Mobility in soil
Based on a log Kow value of 0.20(1) and a regression-derived equation(2,SRC), the Koc value for 1,4-benzoquinone can be estimated to be about 30(SRC). According to a suggested classification scheme(3),this estimated Koc value suggests that 1,4-benzoquinone has high mobility in soil(SRC).
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.
