11. Toxicological Information
11.1 Likely routes of exposure:
Inhalation, skin and eye contact.
11.2 Symptoms related to the physical, chemical and toxicological characteristics:
Acute Eye Toxicity:
Studies indicate that exposures to concentrations of styrene above 200 ppm
cause irritation of the eyes. Styrene causes transient moderate eye irritation
without corneal involvement.
Acute Inhalation Toxicity:
Studies indicate that exposures to concentrations of styrene above 200 ppm
cause irritation of the upper respiratory tract.
11.3 Delayed and immediate effects and also chronic effects from short and long term exposure:
Subchronic:
Overexposure to styrene has been suggested as a cause of the following
effects in laboratory animals and may aggravate preexisting disorders of the
following organs in humans; mild, reversible kidney effects, effects on
hearing, respiratory tract damage, testis damage and liver damage.
Chronic/Carcinogenicity:
The International Agency for Research on Cancer (IARC) has classified
styrene in Group 2B, possibly carcinogenic to humans. IARC concluded that
evidence of carcinogenicity from human health studies, was inadequate and
based the classification on animal and other relevant data. IARC considered
the combined results of these cancer studies to provide "limited evidence" of
carcinogenicity. The relevance of these findings is uncertain since data from
other long-term animal studies and from epidemiology studies of workers
exposed to styrene do not provide a basis to conclude that styrene is
carcinogenic.
Teratology:
Styrene did not cause birth defects in orally-dosed rats, mice, rabbits and
hamsters exposed by inhalation. Styrene given by inhalation for six hours a
day during organ development has been shown to be toxic to fetal mice at
250 ppm and to fetal hamsters at 1000 ppm. Information from human
experience and the results of animal studies suggest no significant risk of
birth defects or reproductive toxicity of styrene to humans.
Mutagenicity:
Styrene has given mixed positive and negative results in a number of
mutagenicity tests. It was not mutagenic in the Ames test without metabolic
activation but gave negative and positive mutagenic results with metabolic
activation. It has also given negative mutagenic results in the Chinese
Hamster Ovary Test, and the Forward Gene Mutation Test and positive
results in the Sister Chromatid Exchange and the Chromosomal Aberration
