Sediments of seven Bohemian Forest lakes were analysed for chemical composition (dry mass, pH, organic carbon (OC), P, Fe, Al) and P fractionation. Differences among sediments from all lakes were small, except Plesné Lake. Due to low pH, no inorganic carbon could be found in sediments. Sediment from Plesne Lake contained the highest concentration of P (4.0 mg/g) in comparison with other lakes (1.8-2.4 mg/g), apparently reflecting the basin geology. The sequential P fractionation according to Psenner & Puczko (1988) was used to examine differences in phosphorus components. The largest part of P (80-90
