About the book
Air is the most essential ingredient for human survival; a person can live without air for only 4 minutes. It is very important that the air is clean because breathing polluted air can cause chronic diseases and disabilities that develop in individuals over the years. The clean air include 78.08% N2, 20.95% O2, 0.93% Argon and 0.03% CO2. Polluted outdoor air is determined by measuring the amount of particulate matter, gases such as C0, Ozone, NO2, SO2, and heavy metals such as lead. The Air Quality Index is based on the measurement of particulate matter (PM2.5 and PM10), Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Carbon Monoxide (CO). According to the United States Environmental Protection Agency standard, the results with the Air Quality Scale are 0-50 good, 50-100 moderate, 100-150 unhealthy for sensitive groups, 150-200 unhealthy, 200-300 very unhealthy, 300-500 dangerous air for human health. In the measurement of indoor air quality, gasses such as CO2, formaldehyde and volatile organic compounds should be measured, as well as particulate substances and ultrafine particles. In addition, the detection of bacteria and molds in the indoor air is necessary to determine the air quality. Polluted air or low quality air causes respiratory tract infections, allergies, asthma, acute and chronic bronchitis, chronic obstructive pulmonary disease, respiratory system cancers, cardiovascular system diseases, especially hypertension. Cardiovascular diseases, cancers and respiratory system diseases are the three most common causes of death in the world when all age groups are taken into account. For these reasons, air pollution ranks first among the risk factors that cause death in the world today. Therefore, fighting for clean air for human health and public health has become one of the most important public health goals of today. The main activities that cause air pollution in the world are industry and power plants, transportation, mining industry, heating, construction activities, waste disposal and some industrial agricultural activities. Precautions for these activities should be taken or increased protection measures.
