sweating, drain pans, poorly-vented kitchenettes
Mold and fungi growth, occupant comfort
Carbon Monoxide (CO)
Leaking vented combustion appliances, car exhaust, parking
garages, furnaces
Shortness of breath, mild nausea, mild headaches, reduce oxygen delivery to organs
and tissue, death
Ozone (O3)Smog, VOCs + NOx, cars burning
gasoline, petroleum refinery, industrial facilities, chemical
manufacturing
Chest pain, coughing, throat irritation, and congestion, worsened bronchitis, emphysema,
and asthma, reduce lung function, scar lung tissue.
