Other Hazards in Your Kitchen
Your Kitchen may also contain these air quality hazards:
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.
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.
Carbon Monoxide (CO) in Other Rooms
Carbon Monoxide (CO) can also be found in other rooms in your home:
