Information
on the Regulatory Treatment of Styrene
Canada
Regulatory Risk Assessment
In 1994, styrene was assessed for toxicity by the two Federal government
agencies (Environment and Health Canada) responsible for administering the
Canadian Environmental Protection Act (1988). The assessment concluded that
the levels of styrene found in the Canadian environment do not pose a threat
to human health or the environment upon which human health depends. The
assessment of styrene is ongoing in relation to the environment.
Worker Exposure Limits
Provincial governments are responsible for worker safety issues including
the setting of occupational exposure limits. Most of the provinces have
set the occupational exposure limit for styrene at 50 ppm, without personal
protective equipment.
