The Deadly Particles that Hide in the World's Air Supply

If it is not for industrial revolution, present technology will not exist. In the mid-eighteenth century, James Watt made a steam engine that allows the UK to produce and distribute energy resources faster than any other country at the time. This made other countries more dependent on all British energy products. In Britain there are all the elements necessary to produce energy, such as hydrocarbon fuels, coal, iron, oil, natural resources. Over time, demand for resources increases.

Fatal particles circulate in our air supply. They are "the life that brings the most serious threat to air pollution." These are small particles of soot and other substances released from diesel engines for trucks, buses and coaches. They are thought to have played a role in the premature death of 8,000 people. Other pollutants known as GMM are causing this damage. GMM is a genetically modified microorganism. These microorganisms are released into the atmosphere and water from factories and laboratories. They are the most life-threatening for elderly people and already ill people. (McCarthy 1)

These small particles and particulate matter will turn clean air into smoke. Particles in the air deteriorate visibility and cause acid rain. Particles may fade the building, but the main problem of particulate matter is the influence on the human body. Medical experts pay special attention to particles smaller than 10 microns, as small particles can damage the lungs, exacerbate asthma, and even cause heart attacks. Inhalation of particulate matter is also fatal to those who suffer from heart and lung diseases.

Particulate matter (PM) is an air pollutant composed of dust and droplet particles. They fall into three categories based on particle diameter: coarse PM, fine PM, and ultra fine PM. Coarse particles are 2.5 micrometers to 10 micrometers, fine particles are 0.1 to 2.5 micrometers, and ultrafine particles are less than 0.1 micrometer. Each size can be inhaled into the body, but the influence of PM on the body varies with size. Coarse particles are filtered by the upper respiratory tract, and these particles accumulate and cause inflammation in the lungs. This can cause eye and sinusitis as well as sore throat and cough. Coarse PM usually consists of heavier and more toxic substances that have short-term effects and can have stronger effects

Very roughly, fine dust can be said to be very small particles in the air. There is a difference between PM 10 and PM 2.5. PM 10 is less than 10 μm in air, while PM 2.5 is less than 5 μm. The smaller the particle, ie smaller than 5 μm, the greater their health risks as they may penetrate the alveoli. Air quality indicators can be calculated based on particles in the air. It indicates that the air is straight "good" or "bad". Unfortunately, there is no unified standard here. Because calculation differs depending on the country, or scale is different. The Wikipedia article on the air quality index contains an easy-to-understand description. In our school we follow the classification established by EPA (US Environmental Protection Agency)
