Tbilisi is among the dangerous three cities where air is polluted - this is the results of a new research by the World Health Organization. According to the results, every 10 people breathe air polluted with 9 toxic substances and solid waste.

Chemical compound nitrogen dioxide, which is the result of exhaust, reaches critical levels in several districts of the capital.

According to Marina Arabidze, Head of Environmental Pollution Monitoring Agency, nitrogen dioxide is increased on Tsereteli Avenue. According to her, the average indexes of nitrogen dioxide with indicator measurement were also revealed on Rustaveli Avenue, Melikishvili Street, Metro station "Technical University" and other streets where there is intensive movement of transport.

The poisonous substance, which is produced by technically faulty automobiles, is accumulated in the human body. This may be the cause of cardiovascular, respiratory and tumor diseases.

Environmentalists say that the green cover is highly needed in the capital. They are criticizing the government because their policy is directed against the green city and trees are damaged every day at the expense of urbanization.

Specialists say that the quality of fuel is a major cause of emissions from vehicles. According to them, the fuel, which the population of the capital uses, is not checked.

The fact that the population breathes polluted air is known for the Ministry of Environment and Agriculture. Despite the alarming data, the agency does not see critical inconsistencies in the World Health Organization survey.

Recent studies have shown that atmospheric air in Tbilisi is becoming more and more dirty. In the streets of the city the cars are multiplied, and their exhaust and construction dust replaces clean air.
