The overall content of polycyclic aromatic hydrocarbons (PAHs) in biomass and coal ashes is comparable, but the content of each of PAHs depend on many factors such as feedstock type, burning conditions. In many countries, such as Canada and USA, both biomass and coal ashes are used for soil amending, if background soil content of PAHs is low. For the reduction of PAHs content different processes could be responsible. Since PAHs represent hydrophobic compounds, they can be adsorbed to soil particles which makes them to be more persistent to the action of various processes. PAHs degradation can be induced by the action of sun light (photodegradation), soil microorganisms, phytoremediation (by fast growing trees like willow, maize, cereals), fungi and others.
