Air quality indoor and outdoor

  1. 1. Air Quality Indoor and Outdoor Reported by: Monica D. Blanco
  2. 2. Air A colorless, odorless, tasteless, gaseous mixture, mainly nitrogen (approximately 78 percent) and oxygen(approximately 21 percent) with lesser amounts of argon, ca rbon dioxide, hydrogen, neon, helium, an d other gases.
  3. 3. Air Quality  the state of the air around us. Good air quality refers to clean, clear, unpolluted air. Clean air is essential to maintaining the delicate balance of life on this planet — not just for humans, but wildlife, vegetation, water and soil.
  4. 4.  Poor air quality is a result of a number of factors, including emissions from various sources, both natural and “human-caused.” Poor air quality occurs when pollutants reach high enough concentrations to endanger human health and/or the environment. Our everyday choices, such as driving cars and burning wood, can have a significant impact on air quality.
  5. 5. Indoor Air Quality  refers to the air quality within and around building structures. • According to the EPA, our indoor environment is two to five times more toxic than our outdoor environment, and in some cases, the air measurements indoors have been found to be 100 times more polluted.
  6. 6. Sources of Indoor Air Pollution  Inadequate ventilation is a primary cause of indoor air pollution and is why pollutants rise in homes during the winter. In highly urbanized and industrial areas, lack of air conditioning and high levels of humidity can increase concentrations of pollutants inside.
  7. 7. Other causes of indoor air pollution Radon - is a noxious gas that arises from the soil and bedrock beneath homes and may be in building materials. It may contain radium or uranium. 
  8. 8.  Tobacco smoke contains 200 known poisons and 43 compounds proven to cause cancer. Second-hand smoke causes 3000 deaths due to lung cancer, 35,000-50,000 deaths due to cardiovascular disease, 15,000-300,000 cases of respiratory infections in infants and worsens asthma in 1 million sufferers. • Mold • Mold, mildew and viruses thrive indoors and must be treated. In the event of mold in your home, call in professionals who use green methods to take care of the problem. This is a serious problem and may even require you to move.
  9. 9. Household Products The average home contains about 10 gallons of synthetic chemical products. Indoor use of pesticides, cleansers, paints and varnishes and air fresheners, candles and incense distribute toxins throughout the home.
  10. 10.  Building Materials Asbestos still lingers in the insulation, paints and floor tiles of many homes.
  11. 11. Outdoor Air Quality  Outdoor air provides people with oxygen, which is essential to human life. The outdoor air we breathe can be polluted with chemicals from vehicles electric power plants, incinerators, and other sources. Air pollution can also come from natural sources such as forest fires, industrial sources such as chemical plants and factories, and smaller sources such as dry cleaners and gas stations.
