Living near a construction site? I'll check what your family might be breathing and create a personalized protection plan.
This tool uses data from California's Proposition 65 list (900+ chemicals), the International Agency for Research on Cancer (IARC), and The Endocrine Disruption Exchange (TEDX) to identify which chemicals are associated with different types of construction. The risk score is an estimate based on distance, activity type, building age, and family vulnerability factors. For a precise measurement, consider hiring a certified industrial hygienist to test your indoor air quality.
Demolition of older buildings (pre-1978) is typically the highest risk because it can release asbestos fibers, lead paint dust, and crystalline silica simultaneously. These are all confirmed human carcinogens. Road work and painting/finishing are also high-risk due to diesel exhaust and volatile organic compounds (VOCs). The good news is that distance dramatically reduces exposure, and a quality HEPA air purifier can filter out 99.97% of airborne particles.
Research shows that PM2.5 particles (fine dust) can travel 20-50 meters from a construction site, while PM10 particles (coarser dust) typically settle within 100 meters. If you're more than 300 feet away, your exposure drops significantly. However, on windy days, fine particles can travel much farther. If you can see dust from construction, your family is being exposed. Running a HEPA air purifier indoors is one of the most effective steps regardless of distance.
