HHRA: Phase 4 Additional Data Collection and Probabilistic Risk Calculations

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.

Acceptable Level of Human Health Risk Resulting from Smelter Contaminants in the Trail Area (Ames, 2001)

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.

Phase 2 Investigation: In Situ Reduction of Lead Bioaccessibility in Soils, Trail, BC (Final)

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)

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, Trail, BC 

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.
