Indoor Air Pollutants - AP Environmental Science
- Identify a common indoor air pollutant released by burning wood.
- Carbon monoxide. Incomplete combustion of wood produces this toxic gas.
- Identify a way to reduce radon levels in homes.
- Improve ventilation. Better airflow dilutes and removes radon gas.
- Identify a method to control indoor humidity to reduce mold growth.
- Use a dehumidifier. Lower humidity prevents mold growth conditions.
- Which indoor air pollutant can be reduced by increasing ventilation?
- Volatile organic compounds (VOCs). Fresh air dilutes volatile organic compound concentrations.
- What is a common biological indoor air pollutant?
- Mold spores. Living organisms that release allergens and toxins.
- Which pollutant is a byproduct of combustion from gas stoves?
- Nitrogen dioxide. Gas stoves produce this respiratory irritant during combustion.
- What is the primary indoor source of lead exposure?
- Lead-based paints. Old paint chips and dust contain lead particles.
- Which pollutant can be controlled by using exhaust fans in kitchens?
- Carbon monoxide. Exhaust fans remove combustion gases from cooking.
- What health issue is commonly associated with exposure to asbestos fibers?
- Asbestosis. Asbestos fibers cause lung scarring and breathing difficulty.
- Identify the indoor air pollutant that can cause allergic reactions.
- Dust mites. Microscopic organisms that trigger allergic responses.
- What is the main health risk of long-term exposure to radon?
- Lung cancer. Radioactive decay damages DNA in lung cells.
- Which indoor air pollutant is a significant risk in buildings with poor ventilation?
- Volatile organic compounds (VOCs). Poor ventilation allows VOCs to accumulate indoors.
- Identify a common household product that releases VOCs.
- Paints and varnishes. These products release various organic chemicals into air.
- Which indoor air pollutant is associated with respiratory infections?
- Mold. Fungal spores can cause respiratory infections.
- Name an indoor air pollutant that can cause lung cancer.
- Radon. This radioactive gas is the second leading cause of lung cancer.
- What is a health effect of exposure to indoor particulate matter?
- Respiratory issues. Fine particles irritate airways and reduce lung function.
- Identify a common indoor air pollutant released by scented products.
- Volatile organic compounds (VOCs). Fragrances contain volatile chemicals that evaporate into air.
- What is the main health effect of exposure to carbon monoxide indoors?
- Headaches and dizziness. CO prevents oxygen transport in blood, causing these symptoms.
- Which indoor air pollutant is a concern with improperly vented fireplaces?
- Carbon monoxide. Poor venting allows CO to accumulate from fireplace use.
- What is a health risk of exposure to indoor lead dust?
- Neurological damage. Lead affects brain development and nervous system function.
- Which pollutant is commonly found in household cleaning products?
- Volatile organic compounds (VOCs). Chemical cleaners release various organic vapors.
- What indoor air pollutant is a concern with humidifiers?
- Mold spores. Moisture in humidifiers can promote mold growth.
- Which indoor air pollutant is primarily a concern in older buildings?
- Asbestos. Used as insulation in buildings before health risks were known.
- What is the primary indoor air pollutant found in tobacco smoke?
- Particulate matter. Tobacco smoke contains fine particles and toxic chemicals.
- What is a common source of indoor ozone?
- Photocopiers. Electronic equipment produces ozone as a byproduct.
- What is a primary source of indoor benzene exposure?
- Tobacco smoke. Cigarettes contain and release benzene compounds.
- Identify the indoor air pollutant that causes irritation to eyes and throat.
- Formaldehyde. This chemical irritates mucous membranes in eyes and throat.
- Identify the indoor air pollutant associated with kerosene heaters.
- Nitrogen dioxide. Kerosene combustion produces this nitrogen compound.
- What is a common symptom of exposure to high levels of indoor ozone?
- Coughing. Ozone irritates respiratory tract and causes coughing.
- What indoor air pollutant is primarily associated with radon decay?
- Radioactive particles. Radon decay releases alpha particles that damage lung tissue.
- What indoor air pollutant is primarily from inadequate combustion?
- Carbon monoxide. Insufficient oxygen during burning creates this toxic gas.
- What is a common source of formaldehyde in indoor environments?
- Pressed wood products. Adhesives in plywood and particle board emit formaldehyde.
- Identify the indoor air pollutant that can cause headaches.
- Carbon monoxide. CO poisoning commonly causes headaches and fatigue.
- Identify a source of indoor sulfur dioxide.
- Burning coal. Coal combustion releases sulfur-containing gases.
- Identify the indoor air pollutant that is odorless and colorless.
- Carbon monoxide. This toxic gas has no detectable smell or color.
- Which pollutant is released from gas appliances and is a lung irritant?
- Nitrogen dioxide. Gas combustion produces this respiratory irritant.
- What indoor air pollutant is a product of incomplete combustion?
- Carbon monoxide. Insufficient oxygen during burning creates this gas.
- Identify a pollutant commonly found in scented candles.
- Particulate matter. Burning wax and fragrances release fine particles.
- Which indoor air pollutant is associated with asthma exacerbation?
- Dust mites. Mite allergens trigger asthma attacks in sensitive people.
- Identify one way to reduce indoor dust mite levels.
- Use allergen-proof mattress covers. Barriers prevent mites from accessing bedding materials.
- What kind of indoor pollutant can be reduced with air purifiers?
- Particulate matter. Filters capture solid particles suspended in air.
