Particles of fine dust are so microscopic that they can not settle and stand in the air. Because of their small mass, they fail to be naturally filtered and retained by inhalation by a person, so they go deeper into the lungs, causing far more damage than particles that remain on the floor. Particularly important is the filtration that is used and how much this fine dust captures. Children often breathe through their mouths, rather than through the nose they provide, less chance of filtering the particles of nasal cilia in the upper respiratory tract.Children are more active than adults, and the volume of air inhaled increases with activities due to increased heart and respiratory rate. Toxins enter the child's blood faster than adults. Children's immune system is not as mature as in adults, so they are more susceptible to inflammatory and allergic reactions.

More than 95% of the world's population breathes unhealthy air and the worst affected are poor nations, a new report said. According to the Global Air Annual Report published by the Institute of Health, long exposure to polluted air causes approximately 6.1 million deaths worldwide in 2016. The report says airborne air breathing leads to heart attacks, lung cancer and chronic lung disease, causing premature death in many of them. Source: www.nationalgeographic.bg

March can be a rough time for people with spring allergies. The reason: Some types of trees start releasing pollen that can be carried in the wind for miles, even into your home, triggering sneezing, coughing and all the other unpleasant allergy symptoms. The particular culprits are trees with fine, powdery, barely visible pollen that can be easily blown away by a strong breeze. Breathing in just a small amount is enough to cause a reaction.

Fine dust particles are microscopic solid or liquid substances suspended in the earth's atmosphere. Sources of particulate matter can be natural (naturally occurring) or artificial. The major sources of natural dust load are: erosion of soil and minerals - mainly by wind and water; microorganisms, for example spores; sea ​​salt; volcanoes; Forest fires Great causes of dust from human activity: Economic activity; construction; transport: gasoline engines, diesel engines; brake wear particles, catalysts, tires, street covers Domestic needs: heating and cooking: gas, oil, wood, coal and other solid fuels; smoking (closed premises); agriculture, including stinging; What impact of PMI have on human health? Dust travels to the body primarily through the respiratory system in which the larger particles are retained in upper airways, and the finer particles (below 10 mm - PM10) reach the lower respiratory compartments, causing damage to the tissues in the lung. Children, adults and people with chronic lung disease, influenza or asthma are particularly sensitive to high PM10. The harmful effect of dust pollution is more pronounced with the simultaneous presence of sulfur dioxide in the atmospheric air. Their synergistic effect on respiratory organs and open mucous membranes was established. Other fine particles are responsible for the increase in allergies, asthmatic attacks, respiratory disturbances, lung cancer, and an increased risk of inflammation in the middle ear of children. It is also suggested that they have an effect on heart and blood circulation (eg heart attack). The particle size of the particles on the respiratory tract depends on particle toxicity such as lead, vanadium, beryllium, aluminum, mercury, hydrocarbon compounds, and particle size: the smaller the particles, the deeper they penetrate the lungs of the human.

How serious is the problem from a purely medical point of view? It's very serious! Indeed, the deterioration in ambient air quality - especially the exceeding of the pollution level by some forms of domestic heating, exhaust gases, fine particulates - in many cases leads to an increase in a certain type of morbidity. What do scientists from Europe say about the air condition of the continent as a whole? Scientists confirm the data on the rise of these five major diseases, which are directly related to the quality of the atmospheric air. Very interesting data is published between 2014 and 2016. Studies have shown that there is a direct correlation between ambient air quality and such diseases as worrying worries, autism, diabetes and even obesity in children. Traditionally we associate the problem with lung disease. What does the statistics say about them? A study by the European Association of Pulmonary Diseases definitely links these diseases to the impaired air quality. In 2016, the statistics for Europe are nearly 420,000. Bulgaria is not left out of these pessimistic forecasts - and there is an increase in our disease. In our country, 50 people per day die from problems and complications related to air quality. For 2014, these are a total of 13 700 people, and in 2016 - 18 200 Which chemical ingredient in the contaminated air is most dangerous to our health? Data shows that the biggest polluter is domestic heating. The second is the exhaust of cars. Harmful chemicals are nitrogen, sulfur dioxide, non-methane volatile organic compounds, ammonia, methane and others. The role of ozone concentration should also not be forgotten.
