3. Health Aspects

3.6 Conclusion

The review of the very extensive literature leads to the following conclusions:

• Liquid styrene is irritant to skin and eyes, while higher vapour concentrations may be irritant to the respiratory tract.
• Exposure to styrene above currently recommended workplace limits may cause reversible effects on the nervous system.

The carcinogenic risk to humans is very low if recommended occupational exposure levels will not be exceeded.
