During the combustion of different types of fuels numerous compounds have been emitted directly into the atmosphere or have been concentrated on the ash particles. In Serbia agricultural biomass has a great potential of use as a renewable energy resource. Biofuels are being increasingly used worldwide in order to replace fossil fuels. Among pollutants which can be emitted, there are many volatile and semi-volatile organic compounds. These compounds are formed due to incomplete combustion or reformed in the flue gas. Their concentrations depend on the fuel composition, combustion conditions and treatment of flue gases before emission. Since some of these compounds, such as polycyclic aromatic hydrocarbons (PAHs) are potentially carcinogenic and toxic, it is necessary to monitor their concentrations in order to optimize the combustion efficiency and to reduce potential environmental risk. Besides, it is imperative to determine major (Ca, K, C, O, H, N), minor (Mg, Na, S, P, Cl) and trace elements (Mn, Zn, Cu, Fe, Mo, B) in ash samples for their suitability for soil amendment and as a soil fertilizer.
