Flashcards
0/15
Carbon Monoxide (CO)
CO is a colorless, odorless gas produced by burning fossil fuels. Exposure can cause headaches, dizziness, and even death at high levels.
Particulate Matter (PM)
PM refers to the mixture of solid particles and liquid droplets in the air. Can cause respiratory issues and aggravate preexisting lung diseases.
Formaldehyde
Formaldehyde is a colorless gas with a pungent smell, used in building materials and household products. It can cause irritation and is a known carcinogen.
Radon
Radon is a radioactive gas that comes from the natural decay of uranium in soil. Linked to lung cancer, especially in smokers.
Volatile Organic Compounds (VOCs)
VOCs are emitted as gases from certain solids or liquids and include a variety of chemicals. Exposure can cause eye, nose, and throat irritation, headaches, and organ damage.
Nitrogen Dioxide (NO2)
NO2 is a reddish-brown gas with a characteristic sharp, biting odor and is one of the several nitrogen oxides. Long-term exposure can decrease lung function and increase the risk of respiratory conditions.
Ozone (O3)
Ozone is a molecule composed of three oxygen atoms. Indoor ozone can cause chest pain, coughing, throat irritation, and airway inflammation.
Humidity
Indoor humidity levels can affect comfort, health, and mold growth. High humidity can lead to mold formation and health issues like asthma.
Temperature
Indoor temperature can affect comfort and health. Extreme temperatures can lead to heat stress or hypothermia.
Biological Contaminants
Biological contaminants include molds, bacteria, viruses, pollen, and dust mites. Can cause respiratory issues, allergies, and spread diseases.
Lead Particles
Lead particles result from lead-based paint or contaminated dust. Exposure can affect brain development and cause behavioral issues, especially in children.
Pesticides
Pesticides used in homes can linger in the air and surfaces. Overexposure can lead to neurological problems and increased cancer risk.
Asbestos
Asbestos is a naturally occurring mineral fiber that when inhaled can lead to lung diseases like asbestosis, mesothelioma, and lung cancer.
Carbon Dioxide (CO2)
CO2 at very high levels can cause headaches, dizziness, restlessness, and breathing difficulties. It is an indicator of proper ventilation.
Mold and Dampness
Mold grows in damp conditions and can produce allergens, irritants, and potentially toxic substances. Exposure can cause respiratory issues and allergic reactions.
