R. Newhook et al., STYRENE - EVALUATION OF RISKS TO HEALTH FROM ENVIRONMENTAL EXPOSURE IN CANADA, Environmental carcinogenesis & ecotoxicology reviews, 12(2), 1994, pp. 453-471
Styrene has been assessed as a Priority Substance under the Canadian E
nvironmental Protection Act. Based on available data, styrene has been
classified as ''possibly carcinogenic to humans'', and tolerable dail
y intakes/concentrations developed based on relevant studies in animal
s. The estimated average total daily intake of styrene by the Canadian
general population is more than 50 times less than the TDI/TDC for ne
urotoxic effects following inhalation, or for foetotoxic effects follo
wing long-term exposure to styrene by the oral route.
