During combustion of coal and biomass different compounds have been generated. There is increasing concern regarding the negative environmental impact of CO2 formed during coal combustion. Biomass, as a source of renewable energy, could play a significant role in the reduction of greenhouse gases concentration. The ashes generated by burning of biomass or coal may pose threat to the environment due to the presence of toxic pollutants, so it is necessary to determine their content in order to estimate the environmental risk. Biomass and coal ashes are not so often characterized for organic compounds such as polycyclic aromatic hydrocarbons (PAHs). Their distribution in ash particles is important because of their toxic and carcinogenic effects to humans and animals. In accordance to this, the determination of PAHs by HPLC/DAD in extracts of ashes from combustion of soybean straw in PKB and coal in Thermal Power Plant was done. In this paper environmental impact of PAHs in biomass and coal ashes was estimated according to their physical and chemical properties
