| Air pollution |
Usually we associate air pollution with the respiratory system and respiratory problems, but if we analyse more deeply the causes of high mortality in the modern world, we will see the fine particles of dust. According to the European Environment Agency's data, over 400 000 people in the European Union die annually due to air pollution, while in Bulgaria die 15 thousand, according to World Health Organization data. The World Health Organization's statistics on a global plan are even more daunting - 7 million a year.
"Not by chance, among the most in-depth publications for the last year in the European Heart Journal, is an analysis of the role of pollution, especially fine particles of heart disease, cardiologist professor Ivo Petrov, national consultant on invasive cardiology. The basis of many studies shows that: Particularly fine dust particles are one of the major risk factors for early development of cardiovascular diseases, along with diabetes, smoking, high cholesterol levels and arterial hypertension. year-olds die from heart disease caused by air pollution, according to a study in the Utah State, where there is a higher compression of fine dust particles, accelerate brain and heart attacks and stroke. "Specialists of the World Health Organization are secure that the fine dust particles and more particularly the PM 2.5 fraction below 25 microns are absorbed and go into the circulatory system and, together with harmful gases, have a toxic effects on the heart, damage the blood vessels, cause heart attacks, stroke, kidney and pancreas. And if smoking, abuse of alcohol and narcotics is a personal choice, the air pollution is a matter of social responsibility.
Fine dust particles are the result of solid and liquid combustion, industrial and other activities. In Bulgaria, two basic sources of pollution are domestic warming (40%) and transport (60%). Only by automobile traffic fine dust particles are 40%. Acceptable levels at the EU border are 25 micro-grams per cubic meter, while the World Health Organization warns that the harmful impact should not exceed 10 micro-grams.
