& Indoor Air, Problems, Glossary
Outdoor Air Pollution & Fine Particulates
The BC Ministry of Environment site explains fine particulates from outdoor air, how they affect us, their sources,
impacts on indoor air quality, how we can control them, and regulations.
Indoor Air Pollution & Ultrafine Particles
Ultrafine indoor particulates, their sources, health problems associated with them, and how to decrease exposure for
better IAQ are offered here by Aerias Air Quality Sciences.
Residential Indoor Air Problems & VOCs
Washington State Department of Health covers IAQ problems with formaldehyde, asbestos, tobacco smoke,
combustion by-products, chemicals, organisms, allergens, mold, and more.
