PHOSPHORUS AND CALCIUM IN THE MUSSELS SINANODONTA WOODIANA (LEA) AND DREISSENA POLYMORPHA (PALL.) IN THE KONIN LAKES

The aim of the study was to analyze the phosphorus and calcium content of the soft tissues and shells of two mussel species, Sinanodonta woodiana (Lea) and Dreissena polymorpha (Pall.), that inhabit the Konin lakes. It was determined that the accumulation of these elements in both of these species was comparable to the levels noted in mussels from the family Unionidae and the species D. polymorpha from other freshwater basins. The loads of the accumulation of these two elements in mussels inhabiting the Konin lakes was estimated.
