Pollutants

Understanding and controlling some of the common pollutants found in homes, schools, and offices may help improve your indoor air and reduce your family’s risk of health concerns related to indoor air quality (IAQ).

 

Radon is a radioactive gas that is formed in the soil. It can  enter indoors through cracks and openings in floors and walls that are in contact with the ground.

 

  • Radon is the leading cause of lung cancer among nonsmokers, and the second leading cause of lung cancer overall.

 

Secondhand smoke comes from burning tobacco products. It can cause cancer and serious respiratory illnesses.

 

  • Children are especially vulnerable to secondhand smoke. It can cause or worsen asthma symptoms and is linked to increased risks of ear infections and Sudden Infant Death Syndrome (SIDS).

 

 

Combustion Pollutants are gases or particles that come from burning materials. In homes, the major source of combustion pollutants are improperly vented or unvented fuel-burning appliances such as space heaters, woodstoves, gas stoves, water heaters, dryers, and fireplaces. The types and amounts of pollutants produced depends on the type of appliance, how well the appliance is installed, maintained, and vented, and the kind of fuel it uses. Common combustion pollutants include:

 

  • Carbon monoxide (CO) which is a colorless, odorless gas that interferes with the delivery of oxygen throughout the body. Carbon monoxide causes headaches, dizziness, weakness, nausea, and even death.

 

  • Nitrogen dioxide (NO2) which is a colorless, odorless gas that causes eye, nose and throat irritation, shortness of breath, and an increased risk of respiratory infection.

 

Volatile organic compounds (VOCs) are chemicals found in paints and lacquers, paint strippers, cleaning supplies, varnishes and waxes, pesticides, building materials and furnishings, office equipment, moth repellents, air fresheners, and dry-cleaned clothing. VOCs evaporate into the air when these products are used or sometimes even when they are stored.

 

  • Volatile organic compounds irritate the eyes, nose and throat, and cause headaches, nausea, and damage to the liver, kidneys, and central nervous system. Some of them can cause cancer.

 

Formaldehyde exposure can cause irritation of the skin, eyes, and throat. High levels of exposure may cause some types of cancer. Formaldehyde is found in resins used in the manufacture of composite wood products (i.e., hardwood plywood, particleboard and medium-density fiberboard), building materials and insulation, household products such as glues, permanent press fabrics, paints and coatings, lacquers and finishes, and paper products, preservatives used in some medicines, cosmetics and other consumer products such as dishwashing liquids and fabric softeners as well as in fertilizers and pesticides.

 

Asthma triggers are commonly found in homes, schools, and offices and include mold, dust mites, secondhand smoke, and pet dander. A home may have mold growing on a shower curtain, dust mites in pillows, blankets or stuffed animals, secondhand smoke in the air, and cat and dog hairs on the carpet or floors. Other common asthma triggers include some foods and pollutants in the air.

 

  • Asthma triggers cause symptoms including coughing, chest tightness, wheezing, and breathing problems. An asthma attack occurs when symptoms keep getting worse or are suddenly very severe. Asthma attacks can be life threatening. However, asthma is controllable with the right medicines and by reducing asthma triggers.

 

Molds are living things that produce spores. Molds produce spores that float in the air, land on damp surfaces, and grow. Inhaling or touching molds can cause hay fever-type symptoms such as sneezing, runny nose, red eyes, and skin rashes. Molds can also trigger asthma attack.
