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.
HHRA: Phase 2: Screening-level deterministic risk calculations (1998)

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.
Sentinel Homes Report (1999)

Sentinel Homes Report (1999)

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.
HHRA: Phase 1 Problem Formulation (1997)

HHRA: Phase 1 Problem Formulation (1997)

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.
Exposure Pathways Investigations (1995)

Exposure Pathways Investigations (1995)

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.
HEPA House Cleaning Pilot Project (1994)

HEPA House Cleaning Pilot Project (1994)

This study looked at whether regular (once every 6 weeks) thorough cleaning of floors using HEPA filter equipped vacuum cleaners would have a measurable effect on children’s blood lead levels. Fifty-five homes received the regular cleaning, while 56 homes did not.
Research Realities in Trail (1993)

Research Realities in Trail (1993)

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.
Trail Lead Study Report (1990)

Trail Lead Study Report (1990)

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.
