Скачать или смотреть Sources and potential health effects of Indoor Air Pollutants

Indoor Air Pollutants are often more concentrated than outdoor pollutants, especially in poorly ventilated spaces. These pollutants come from everyday activities, materials, and even the building itself—and they can have serious health consequences.

🔍 Major Sources of Indoor Air Pollution
Source Type Examples & Details
Combustion Sources Cooking with biomass, kerosene, coal, or gas stoves; tobacco smoke; candles
Building Materials Asbestos, formaldehyde in insulation and furniture, lead-based paints
Household Products Cleaning agents, air fresheners, pesticides, adhesives, paints
Biological Contaminants Mold, dust mites, pet dander, pollen, bacteria, and viruses
Outdoor Pollutants Indoors Radon gas from soil, vehicle exhaust, industrial emissions entering through windows
Electronic Waste & Appliances Off-gassing from plastics, flame retardants, and ozone from printers or copiers
You can explore a full list of sources on the EPA’s Indoor Pollutants and Sources page.
