Share of air transport pollution reached 63%


The share of car exhausts in overall air pollution in Bashkortostan increased from 49 to 63% for the last decade, deputy Minister of nature management and ecology RB Olga Lazdina reported.

“The main reason of this jump is the increase of the number of transport vehicles on our roads” – she said – “Because Republican car fleet increased nearly twice since 1998. At that the average age of the cars remains too high – more than 10 years and it anticipates low level of ecological indices of their engines”.

Transport remains the main air polluter in Bashkortostan as well as all over Russia and this problem grows up every day. In 2008 the volume of car exhausts increased in Bashkortostan 46 thousand tons, making up 713 thousand tons, as compared with 2007.

“The world experience determines several most efficient methods for lowering the negative effect of car exhausts”  -Olga Lazdina says – “First, this is the improvement of fuel quality; the usage of various additions; the replacement of traditional fuels by alternative sorts of fuel, natural gas, for example; construction of modern highways with small number of traffic lights, better design of car engines and toughening of state control over observation of state standards on engine toxicity and black smoke”.

Bashkortostan was the first region in Russia, which refused from the usage of ethyl benzenes and diesel fuel with sulfur content more than 0,2%. Besides, Republican enterprises started production of methyl tertiary butyl ether, used as an oxygen-containing addition for fuel. This addition reduces the content of carbon monoxide in car exhausts by 30%.

“Natural gas can be also considered the real alternative to oil in the nearest future” – Olga Lazdina says. By the beginning of 2009 there were more than 80 gas-cylinder transport vehicles in the Republic as well as 98 gas-filling stations. 60 technical centers are busy with re-equipment of local transport for working with gas at present time.
