This report shares the 2007 Children’s Blood Lead Clinic results. This includes participation rates, results, and environmental conditions. Participation is voluntary. Rates are provided by neighbourhood and area. The blood lead level geomean based on the 2007 fall clinic was 5.2 µg/dL. Environmental conditions refer to Pb in air at different times of the year.

This report responds to a request by Teck (then Cominco) as a “responsible person” under Section 18 of the BC Contaminated Sites Regulation for a formal recommendation on the acceptable level of human exposure and health risk for the site. Recommendations were prepared by the Medical Health Officer and transmitted to BC Ministry of Environment.
In 2000, the Trail Community Lead Task Force consulted with the local community and international experts as it worked to develop recommendations following 10 years of research, program development and monitoring. This report includes notes about the meeting content reviewed and Q&A, summarizes key discussion points, and presents proposed actions collated by the review group.

This report covers the second phase studying 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 second set of bench-scale trials using phosphate, iron and pulp mill organic residual were conducted, and what the results suggested.
Phase 2 Investigation: In Situ Reduction of Lead Bioaccessibility in Soils (2000) Read More »
Learn whether substances other than lead pose a potential concern in Trail. This phase further evaluates risks associated with arsenic and cadmium, incorporating new data from air and indoor dust monitoring. The potential for adverse health effects from long-term residence in Trail was limited. Continued monitoring of air concentrations for arsenic and cadmium was recommended.

This report covers the third 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 third set of trials using phosphate, iron and other potential amendments were conducted, and what results suggested.
Learn about whether any substances other than lead pose a potential concern in Trail. This phase eliminated five metals from further evaluation Risks from arsenic and cadmium were found to be low, but recommendations were made for further data collection and risk analysis for these remaining two metals of potential concern.

Find out what was learned by monitoring 35 “sentinel” homes in Trail from 1994 through 1998. This monitoring network was set up mainly to enable measurement of the changes in lead levels in and around homes after the new lead smelter began operation in early 1997.
