Shell states that Alberta Health and Wellness (AHW) recently evaluated the
potential health effects associated with short-term SO2 exposures. Based on a
review of human clinical evidence, AHW (2006) concluded that healthy
individuals can be exposed to concentrations up to 26,000 μg/m 3 (10 ppm) with
transitory effects on pulmonary function, even under extreme conditions
involving hyperventilation, mouth-only exposure and heavy exercise. It is
inaccurate to state that AHW concluded that healthy individuals can be exposed
to the mentioned concentrations, as the document referenced is a review of the
available literature and reporting of the associated findings. The document was
not intended to reflect AHW’s evaluation, or conclusions, regarding human
health effects associated with SO2.

In 2006, Alberta Health and Wellness released a report on the potential health
effects associated with short-term exposure to low levels of SO2. The goal of the
report was to “provide a comprehensive review of the available primary scientific
literature in order to develop a quantitative understanding of the current state of
knowledge with respect to the dose-response relationship between exposure to
