Abstrakt: PM2.5 generally represents fine fraction of atmospheric aerosol. Fine particles may remain in the atmosphere for days or even weeks and therefore they may be transported over long distances. Moreover, they may increase the background levels of atmospheric aerosol mass far from their origin. They have important adverse health effects and in the same time, they influence climate due to their direct and indirect effects on Earth radiative balance. To know the origin of PM2.5 aerosol, its chemical composition can serve as the diary of contacts with aerosol sources and transformations. Therefore it is necessary to study PM2.5 chemical composition if the fine aerosol sources should be revealed. A rural background site study can serve as a basis enabling to determine the real influence of larger sources like cities or an industry.
