Pollutant
Sources
Health Effects
Carbon Monoxide (CO) Furnaces, vehicle exhaust, tobacco smoke, and other combustion processes Causes angina, impaired vision, and reduced brain function; High concentrations can be fatal.
Carbon Dioxide (CO2) Human respiration and all combustion processes Only at high levels, (>1.5% of air or 15,000 ppm), loss of mental acuity noted
Ozone (O3 ) Copy areas and other electrical equipment; Outside air Decrease in lung function; Aggravation of asthma, chest pain, and inflammation of lung tissue
Mercury Medical equipment, electrical switches, some light bulbs, thermostats, and batteries Cough, chest pain, nausea, diarrhea, long-term weight loss, irritability, and memory loss
Pesticides Used in food preparation areas, on indoor plants, wood and other products; Can be tracked in from outside Depends on active and inert ingredients in the pesticide and the dose received
Formaldehyde Volatilization from building furnishings, certain types of plywood, glues, adhesives, and tobacco smoke Causes burning in eyes; Irritates mucous membranes and respiratory tract; Probable human carcinogen
Asbestos Deteriorating, damaged, or disturbed insulation, fireproofing, acoustical material, and tiles Causes asbestosis (lung disease), lung, chest, and abdominal cancer; Known human carcinogen
Volatile Organic Compounds (VOCs) Paints, cleaners, copiers, tobacco smoke, insecticides, personal care products, and combustion vapors Some lead to nausea, dizziness, eye, respiratory, and mucous membrane irritation; Some linked to cancer
Environmental Tobacco Smoke Tobacco combustion: cigarettes, cigars, pipes Known human carcinogen; Aggravates asthma
Nitrogen Oxides Combustion processes Eye, respiratory, and mucous membrane irritation; Exacerbates asthma, bronchitis, and emphysema
Dust Multiple sources, including soil, fleecy material, pollen, combustion processes, and renovations Particles may contain lead, pesticide residues, toxic materials, irritants, and/or carcinogens.
Lead Lead-based paint, drinking water, food, and contaminated soil or air Damage to brain, kidneys, nervous system, and red blood cells; Children are especially susceptible.
Allergens and Pathogens Areas of high humidity or significant amounts of moisture; Entrance growth of biological material Several diseases such as tuberculosis, measles, infections, influenza, Legionnaires disease transmitted by air; Molds and pollen contribute to allergies.
Radon Naturally occurring radioactive gas found in earth- ground buildings, well-water, and some materials Known lung carcinogen
Polychlorinated Biphenyls Transformers, capacitors, circuit boards, oils, and other electrical devices Acute effects unknown; Chronic effects include respiratory, dermal, gastro-intestinal, and reproductive problems. Probable human carcinogen
