This report covers the first phase of work to study whether the lead in Trail soils could be rendered less available to children by adding something to reduce its solubility in the human gastrointestinal tract. Learn how the first bench-scale trials using phosphate were conducted, and what the results suggested.

This article was published in Environmental Geochemistry and Health (1996). It summarizes the approach and studies from the first 5-years of the Trail Lead Task Force. The Task Force had responsibility for developing a strategy to reduce children’s blood lead levels in Trail. With funding from the provincial government, the smelting company and the municipal government,
Learn what were the key factors associated with higher blood lead levels in Trail children in 1994. This study involved a more comprehensive look at links between the environment and children, following up from the first such study in 1988.

This paper describes the limitations and challenges of studies of children’s lead exposure. It argued that insistence on proof of effectiveness of each potential intervention prior to moving ahead would lead to inaction. A case was made for moving ahead, evaluating the package of actions using the trends in annual blood lead data for Trail.

This study, conducted by UBC, laid the groundwork for the formation of the Trail Community Lead Task Force in 1990, and provided helpful guidance for the research and program development work through to 2000. Learn what the researchers discovered about the key factors affecting children’s lead exposure in Trail at that time.
