Air pollution. Main problems and ways to solve them

Air pollution is one of the main types of anthropogenic pollution. Consists of the emission into the atmosphere of chemicals, solid particles and biological materials capable of causing harm to humans and other living organisms

Acid rain. Acid rain is formed as a result of the reaction between water and pollutants such as sulfur dioxide (SO2) and various nitrogen oxides (NOx). These substances are emitted into the atmosphere by road transport, as a result of the activities of metallurgical enterprises and power plants, as well as during the burning of coal and wood

Smog. Smog is excessive air pollution with harmful substances that are released as a result of industrial production, transport under certain weather conditions

The burning of oil, coal and gas, the creation of landfills, the development of motor vehicles, irrational agriculture lead to emissions of greenhouse gases (carbon dioxide, methane, nitrous oxide), which, entering the Earth's atmosphere, intensify the "greenhouse" effect, which leads to global climate change

Air pollution is responsible for 40% of deaths from coronary heart disease, 7% from pneumonia, 8% from stroke, 6% from chronic obstructive pulmonary disease, 7% from lung cancer, and another 32 premature deaths from non-communicable diseases.

Thank you for attention

The ozone hole is a local drop in ozone concentration in the stratosphere by 10-40%. This is due to the effect of freons, the decrease in the amount of oxygen during spaceship launches and jet flights. It is clearly detected at excessively low temperatures
