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.

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.

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.

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.

Learn about whether any substances other than lead pose a potential concern in the local environment at Trail. This is the first in a series of reports on the subject. Phase 1 identifies eight other metals to be assessed in the later phases.
