Fall 2008 Blood Lead Report
This report shares the 2008 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 2008 fall clinic was 5.9 µg/dL. Environmental conditions refer to Pb in air at different times of the year.

HHRA Phase 4: Additional Data Collection and Probabilistic Risk Calculations (2008)
Learn whether substances other than lead pose a potential concern in Trail. This phase evaluated peoples’ exposures to a broader suite of metals than had been considered in previous phases. The conclusion was that risks were low and the potential concern to watch going forward was arsenic and cadmium concentrations in outdoor air.

Fall 2007 Blood Lead Report
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.

Acceptable Level of Human Health Risk Resulting from Smelter Contaminants in the Trail Area (Ames, 2001)
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.
Program Review Report (2000)
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.

Phase 2 Investigation: In Situ Reduction of Lead Bioaccessibility in Soils (2000)
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.

HHRA Phase 3: Screening-Level Deterministic Risk Calculations, Revised (2000)
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.

Phase 3 Investigation: In Situ Reduction of Lead Bioaccessibility in Soils (1999 – Draft)
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.
HHRA: Phase 2: Screening-level deterministic risk calculations (1998)
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.
