Environmental pollutants emission from public transport assessment and analysis in Vilnius city, in The 8th International Conference “Environmental Engineering”: Selected papers. Ed. by D. Čygas, K.

Abstract: The transport is one of the major air polluter. The transport sector accounts for about 75% of total pollutants in Lithuania. One of the most characteristic feature of environmental pollution from transport is that in particular pollution is the largest on the city streets, especially in densely populated and high-intensity areas of transport. On the basis of emissions from internal combustion engine calculations, the emissions of carbon monoxide (CO), hydrocarbons (CH), nitrogen oxides (NOx), sulfur dioxide (SO2) and particulate matter (PM) emissions from Vilnius bus fleet vehicle engines were determined. It was found out that the largest pollutants are carbon monoxide and its emission is changing from 1,000 to 1,500 tons per year. In addition, in the article presented environmental pollution from public transport during the 2002-2009 year changing analysis in Vilnius city. Vilnius bus fleet regularly updates its vehicles. Assessing the ecological situation in the city of Vilnius, now park is exploiting 100 average age buses and in the next year is planning to buy new gas-efficient buses. The authors present modelling way for determining the future influence of public transport on the environment according Vilnius bus fleet technical content.
