Styrene is used mainly in the manufacture of polystyrene resins and of
copolymers with acrylonitrile or 1,3-butadiene. Five occupational exposure
scenarios were identified with highest exposures occurring within the
glass-reinforced plastics (GRP) industry, partly because of the use of open
moulding techniques and hand laminating (1.6 to 167 ppm 8hr TWA).
The European Scientific Committee on Health and Environmental Risks (SCHER)
adopted its opinion about styrene as far as human health is concerned. Consumer
exposure may result from emissions of building materials and carpets, from food
and food packaging, and from styrene-containing resins used for repair works
and boat building as well as from tobacco smoke. The combined exposure
(excluding tobacco smoke) was estimated to be at the level of about 90
micrograms per day.
