Ground Level Ozone Precursors: Emission Changes in Lithuania 1990–2006
Keywords:ground level ozone precursors, intensity of ground level ozone precursors, Lithuania.
AbstractLithuanian national strategy for sustainable development is aiming to reduce air pollution per GDP unit significantly and to ensure compliance with international commitments in the air pollution sphere. Ground-level ozone (O3) is one of the most important secondary air pollutants, which is assigned to be harmful to environmental and human health and is one of the main problems of air pollution in cities. This paper aims to overview the changes in the emissions of ground level ozone precursors and their ozone forming potential as well as the achieved progress in foreseen goals. During the analysis period (1990 - 2006) emissions of ground-level ozone precursors declined twofold in Lithuania. After transitional decline intensity of ground level ozone precursors also significantly decreased due to advanced technologies, more efficient energy consumption and changes in fuel mix. However, intensity of ground-level ozone precursors in Lithuania was higher compared to the old EU member states on average, therefore much more attention should be given to special air pollution mitigation measures.
