Currently, one of the main sources of air pollution is vehicles,
which have an extremely negative impact on the environment, Vasif
Aliyev, Deputy Head of the National Hydrometeorology Service of the
Ministry of Ecology and Natural Resources of Azerbaijan, Trend
reports.
“As the economy develops and cities grow, so does the number of
vehicles. Traffic congestion on the streets as a result of the
increase in the number of vehicles causes persistent air
pollution,” Aliyev said.
The amount of pollutants emitted by vehicles into the atmosphere
has doubled since 1993, the expert added.
Calculations show that when burning the same amount of gasoline
and diesel fuel, the number of pollutants emitted into the
atmosphere in diesel fuel is many times higher, he said.
“If during the combustion of one ton of gasoline during the
operation of vehicles, 20 kg of nitrogen oxide, 1.6 kg of sulfur
dioxide, 34 kg of hydrocarbons, 2 kg of solid particles (soot and
others), 1.4 kg of aldehydes (organic acids) are emitted into the
air, then the combustion of one ton of diesel fuel releases 33 kg
of nitrogen oxide, 6 kg of sulfur dioxide, 20 kg of hydrocarbons,
16 kg of solid particles (soot, structure), 6 kg of aldehydes
(organic acids) into the air,” Aliyev said.
The service representative added that the use of compressed gas
in the vehicles used by 'Baku Bus' company is commendable, as LPG
vehicles are less polluting.
