Gas Stove Emissions (NO2 and Benzene)
Gas stoves release nitrogen dioxide and benzene even when turned off. A 2022 study linked gas stoves to 1 in 8 childhood asthma cases. Benzene is a known carcinogen that spreads throughout the home.
Carbon Monoxide (CO)
CO is a silent killer — colorless, odorless, and lethal at high concentrations. It binds to hemoglobin 200x more than oxygen. Every home with fuel-burning appliances needs a CO detector.
Volatile Organic Compounds (VOCs)
VOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Cockroach and Pest Allergens
Cockroach saliva, feces, and decomposing body parts become airborne allergens. They are a major trigger for asthma in children, especially in urban environments. Mouse urine proteins cause similar reactions.
PFAS (Forever Chemicals) in Household Dust
PFAS chemicals from nonstick cookware, stain-resistant fabrics, and waterproof clothing accumulate in household dust. They never break down in the environment or the human body. Linked to cancer, thyroid disease, and immune suppression.
