Residential Indoor and Outdoor Metals Concentration Data from Regina

146 homes in Regina, Saskatchewan, participated in this study of metals in fine particulate matter (PM2.5). Health Canada and the Regina Qu’Appelle Health Region collected 5-day indoor and outdoor exposure samples during winter and summer 2007. The dataset provides summary results from ICP-MS analysis, presented separately for homes with and without smokers.

Use Cases

• Compare indoor versus outdoor metals concentration levels for specific PM2.5 components.
• Analyze seasonal variations in metal exposure by comparing winter and summer 2007 sampling sessions.
• Assess the impact of environmental tobacco smoke by contrasting results from homes with and without smokers.
• Model population exposure to specific metals like lead or arsenic in a residential urban setting.

Strengths

• Data from 146 participant homes provides a substantive sample for a single-city study.
• Includes separate analysis for a key confounding factor: homes with and without smokers.
• Covers two distinct seasons (winter and summer 2007) for temporal comparison.

Limitations

• Sample size is limited to one city (Regina), restricting geographic generalizability.
• Data is from 2007 and may not reflect current building materials, lifestyles, or air quality.
• The dataset provides summary statistics, not raw, high-temporal-resolution measurements.
