Toxic substances list: benzene
Benzene is used in Canada in a variety of ways that result in it entering the Canadian environment. Vehicle emissions are the major source of benzene release to the environment. Releases of benzene result in measurable concentrations in the various media to which humans and other organisms may be exposed. In Canada, the primary source of human exposure to benzene is ambient and indoor air; food and drinking water contribute only minor amounts to the daily intake of benzene.
