Air Pollution


Indoor air

Indoor air quality is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IA Q can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, micro contaminants (mold, bacteria), or any mass or energy stress or that can induce adverse health conditions.

Sick building syndrome is a term which refers to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.

Statistics about indoor air quality and what the standards are

  • Air pollution affects kids more than adults due to higher concentrations of polluted air in their systems per body size.India is the country with the worst air quality in the world. The European Union would save 161 billion euros a year if deaths caused by air pollution were diminished. In large cities, over 80% of fatal pollutants that cause lung damage come from cars, buses, motorcycles and other vehicles on the road.According to the World Health Organization, there are as many deaths (1.3 million per year) in the world due to air pollution as there are deaths due to car accidents. The average adult breathes 3,000 gallons of air every day.Each weekend, more than 800 million gallons of gas per year are used in lawn mowers in the United States, producing up to 5% of total air pollution.Vehicle exhaust contributes 60% of all carbon monoxide emissions in the United States and can go to over 90% for large cities.The Great Smog of London in 1952 was one of the worst air pollution events in history with over 8,000 deaths.The largest cause of air pollution in Europe is road transportation with over 5,000 people dying each year from lung cancer and heart attacks caused by vehicle

causes and effects of indoor pollution

  • indoor air pollution causes irritation in the throat, nose, lungs and eyes. It causes breathing problems and aggravates existing health conditions such as emphysema and asthma.Contaminated air reduces the body’s defenses and decreases the body’s capacity to fight other infections in the respiratory system.Frequent exposure to polluted air increases the risk of cardiovascular disease. Breathing air that is filled with fine particulate matter can induce hardening of the arteries, triggering cardiac arrhythmia or even a heart attack. People who exercise outdoors are susceptible to the adverse effects of air pollution because it involves deeper and faster breathing.Acid rain contains hydrogen ions, which can damage trees, crops, harm marine animals and induce corrosion in metals. smog causes harmful health effects in humans and animals. Studies have shown signs of black lung disease in dolphins of due to high concentrations of carbon particles in the air. People afflicted with heart disease, children and older people are more sensitive to air pollution
