Measuring the degree of air pollution
We know the level of air cleaner in a particular geographical spot through the air quality index, which is useful in determining whether a valid area to be inhabited or not, is also useful in measuring the effectiveness of the application of policies to reduce air pollution, the Environmental Protection Agency (in English: Environmental Protection Agency) developed the so-called air quality index (English: air quality index) to measure air quality in the atmosphere, which is as follows: 
Can be seen air pollution rates in each country around the world directly through the following link: Click here. 
Prevention of atmospheric pollution
You can do some steps to reduce the vulnerability of people to the polluted air after checking the air quality index in the desired area by using sites that provide this information, and these steps:
- The study of the movement of wind and knowledge of those who wind Mstahbh with them come from polluted air to avoid.
- Identify the times that abound in which air pollutants during the day to avoid them; Where pollution levels rise the presence of sunlight in areas where emissions of vehicles and factories abound, for example.
- The use of air purifiers inside the house to reduce the proportion of pollutants in it.
- Minimizing do daily activities during which people are exposed to air pollution, and do Bmjhodat physical light rather than stressful activities; Such as the replacement of walking about running, which can be allowed to enter large amounts of polluted air into the body.  
The most important types of pollutants and how to prevent them
Despite the great interest of the ozone layer (in English: Ozone) in preventing harmful ultraviolet rays from reaching the Earth, the ozone gas is very harmful when his presence near the surface of the earth; Because it is the main component of smog (in English: Smog), which causes some diseases to people, and produces when the resulting emissions reaction from the burning of fossil fuels in vehicles, factories, and power plants with the sun's rays, and increase the amount of ozone when increasing the emissions mentioned ratio, especially at peak hours when the movement of traffic to be at its height. 
Prevention method varies from ozone damage as a result of a different degree of air quality indicator in a given area as follows: 
Know the exact (particle in English: Particulate Matter) as small solid and liquid particles that can enter the lungs and cause many diseases of the respiratory system, and these particles are divided into two parts; Particles ranging from some of the thickness of between 2.5-10 micrometer called (PM10) and arise from the dust on the road, and milling and crushing operations, and particles of up thickness to less than 2.5 micrometers called (PM2.5), and arise from different combustion processes such as the burning of forests, or fossil fuels, or can be created from the merger of ammonia emissions with factories, and can not see these contaminants without using electron microscopy. 
You can fine particulates (PM2.5) to move to the lungs and other body organs through the bloodstream, leading an increase in the human body to the heart attack (in English: Heart Attacks), and disturbance of heart systems (in English: Cardiac Arrhythmia), and exacerbation of asthma, and bronchitis, as well as infection with difficulty breathing, chest tightness, cough, palpitations, fatigue, and other symptoms, while causing (PM10) pain in the eyes, and runny nose, as well as coughing, shortness of breath for people suffering from heart disease and lung, 6] must therefore reduce the stressful activities of the various external activities to reduce the incidence of the risks of these pollutants, but this varies depending on the health status of people as it varies depending on the air quality indicators, which are as follows: 
Shaped carbon monoxide from incomplete combustion of the element carbon, which is colorless, odorless, and commonly found in cold weather conditions as a result of the effect of cold temperatures on the combustion process is complete, so it remains near the surface of the ground, vehicles of different means of transportation is the largest producer of this gas , in addition to factories, forest fires, burning wood stoves, this gas and lead to a decline in the amount of oxygen gas that reaches the body, and increase the proportion of this gas in large quantities in the body lead to death in some cases, causes carbon monoxide confusion, dizziness , blurred vision also in the case of presence by high. 
Monoxide causes carbon many of the health problems of different people, but the embryos, people with heart disease are the most susceptible to the effects of this gas, and the effects of exposure: nausea, headache, and fatigue, as well as loss of consciousness sometimes, and difficult presence of this gas concentration the great outdoors, but there is indoor more, and the effects of this gas show in the outer atmosphere in the places of fresh air or moderate. 
Prevention method varies from damage to the first carbon dioxide gas as a result of a different degree of air quality index in a particular area as follows: 
Produces carbon dioxide sulfur in plants that use coal or fuel that contains sulfur in its work, such as oil refineries, power plants, and difficult this gas to enter the human body through the nose, but it seeps into the body when breathing person through the mouth, and this causes gas to many diseases and health problems, including: shortness of breath, chest pain, and when exposed to this gas in the long term compounded some health problems such as asthma, cough, and vascular disease, and lung disease chronic symptoms of this gas faster and appear when it enters to the body closely, it is worth mentioning that the sulfur dioxide contributes to the formation of fine particles also.  
There are many steps that can be done to avoid the effects of carbon dioxide sulfur, and these steps as follows:
