Description

In response to recommendations of the final report of the Provincial Advisory Committee on Public Safety and Sour Gas released in December 2000, Alberta Health and Wellness commissioned reports on the health effects of low-level exposure to hydrogen sulphide (H2S) and sulphur dioxide (SO2). The present report on hydrogen sulphide is the first of four reports. It focuses on the health effects information on short-term exposures to H2S at concentrations in the range of 0 to 100 ppm. A principal aim of the work was to update the conclusions reached in 1988 by the Ad Hoc Committee on H2S Toxicity. The review focused on the health effects of short-term exposures to low levels of H2S on normal, healthy individuals. Issues surrounding “hypersusceptible” individuals were not directly addressed. Similarly, health effects that might occur secondary to the odour of H2S were not specifically addressed.

Description

In this study, cow’s milk from farms which are potentially affected by polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran (PCDD/F) emissions from various industries in Ft. Saskatchewan, including the Dow Chemical EDC/VCM facility, were sampled and analyzed for PCDD/F. The results were compared with samples from reference farms as well as supermarket milk.
