During exposure to ultraviolet light water treatment decreases in concentrations of PAHs. PAH removal efficiency was in the range from 45 to 62% for the total amount of these compounds, while for the individual is in the range from 17 to 67%. Percentage of degradation depended on the exposure time and the connection rings in the hydrocarbon molecule."]
