Özet
Anthropogenic inputs of pollutants such as heavy metals into the marine environment have increased their levels to a large extent within the past few decades. The available literature on heavy metal bioaccumulation by freshwater crayfish has been analysed. A very uneven data distribution was found; Orconectes, Cambarus Procambarus and Astacus are the most commonly investigated orders of crayfish. Furthermore, Zn, Cu, Pb and Cd are the most intensively researched heavy metals, and only infrequently are investigations of other metals documented. At some conditions bioaccumulation levels of some heavy metals were as follows Mn> Zn >Cu>Ni>Cr>Pb>Cd. Accumulated metal concentrations are interpreted in terms of different trace metal accumulation patterns, dividing accumulated metals into two components - metabolically available metal and stored detoxified metal. The following chapter will focus on the bioaccumulation of some heavy metals in freshwater crayfish.
