Total reflection X-ray fluorescence spectrometric method was developed for elemental analysis of lead and nickel contaminated natural biofilms grown on polycarbonate substrates. The biofilms were grown in the Lake of Velence for 4 weeks and then in the laboratory in contaminated lake water for other 2 weeks. It was established that the accumulation of these bivalent cations were practically the same and in their presence the accumulation of zinc decreased by approximately 20% while the other elements (Ca, K, Fe, Mn, Sr, Ti, Rb) showed smaller changes within the statistical interval. From biological point of view, these two bivalent cations reduced the abundance of the algae, to a similar extent; however, the total biomass production was significantly hampered only by nickel (14%).
