Description

A comprehensive list of priority environmental contaminants were monitored in blood serum of pregnant women in 2005, with the purpose of establishing the magnitude of exposure to environmental contaminants during pregnancy for women living in all regions of Alberta. The objectives were specifically to examine the influence of age, geographic location, and seasonality on the maternal serum concentrations of man-made or naturally occurring chemicals that women may absorb from food, drinking water, air, soil, household dust, or commercial products. This is the first Province-wide biomonitoring study for Alberta.

Description

A comprehensive list of priority environmental contaminants were monitored in blood serum of healthy children with the objective to examine the influence of age and to compare these new data with concentrations in pregnant women that were reported previously for the same region. In general, concentrations of detected contaminants were either lower or similar to concentrations reported in other studies of children in North America or around the world.

Assessment of the potential lifetime cancer risks associated with exposure to inorganic arsenic among indigenous people living in the Wood Buffalo region of Alberta

Description

The toxicity of arsenic is a subject of considerable research, as well as some controversy, particularly in relation to its potential to cause cancer. In order to better understand and assess the significance of the elevated cancer risk from arsenic exposure, Alberta Health and Wellness retained Cantox Environmental Inc. (CEI) to review previous research and assess the potential cancer risk using refined methodology consistent with that typically used by CEI. The work was meant to serve as a “second opinion” of the lifetime cancer risk that could be presented to people living in the Wood-Buffalo region from arsenic exposure.

Health effects associated with short-term exposure to low levels of sulphur dioxide (SO₂) : a technical review

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 SO2 is the second of four reports. The goal of these reports 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 these contaminants (H2S and SO2) and health effects based on the weight of evidence in the peer-reviewed scientific literature.

Description

This report summarizes the results of a community exposure and health effects assessment undertaken in Fort Saskatchewan to assess the impact of airborne contaminants on the health of the population. The report describes the population and personal distribution of exposure to airborne chemicals and particulates in the city of Fort Saskatchewan and the surrounding region. Using a personal exposure model, the relative contribution of various exposure sources and pathways to airborne chemicals is estimated and associations between exposure to airborne chemicals and human health effects are described.

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

The Alberta Oil Sands Community Exposure and Health Effects Assessment Program was designed to assess exposure and associated health effects by direct measurement of personal exposure, direct measurement of biomarkers, and daily logs of a participant's activities. The study was modeled after the Total Exposure Assessment Method (TEAM) approach developed by the United States Environmental Protection Agency. The TEAM approach is based on four fundamental characteristics: direct measurement of all routes of exposure (breathing, ingestion, and skin contact), direct measurement of biomarkers, daily logs of a participant’s activities, and a representative probability sample.

Description

Over the past few decades, emphasis has been placed on environmental toxicology and modeling of pollutant fate and transport in the environment to deal with human health concerns. Sources of pollution such as stack emissions, industrial effluents, and toxic wastes are being monitored and are reasonably well understood. However, at the time of this report human exposure to contaminants from all pathways (air, food, drinking water, and direct skin contact) is largely unknown. Several countries, as well as the World Health Organization, are implementing exposure and health effects assessment approaches to address human health concerns related to environmental and other factors. This document describes an application of the approach in Alberta to assess human exposure to contaminants from oil sands industrial activity.

Description

This report provides an overview of the Alberta Oil Sands Community Exposure and Health Effects Assessment Program Main Study. The report describes the population and personal distribution of exposure to airborne chemicals and particulates in the city of Fort McMurray. Using a personal exposure model, the relative contribution of various exposure sources and pathways to airborne chemicals is estimated and associations between exposure to airborne chemicals and human health effects are described.
