Bioaccumulation of selected trace elements in lung nematodes, Pseudalius inflexus, of harbor porpoise (Phocoena phocoena) in a Polish zone of the Baltic Sea.
Concentrations of Cd, Pb, Cu, Zn, Cr, Co, Ni, Mn and Fe were determined by AAS in lung nematodes and their host organ of harbor porpoise in the Polish zone of the Baltic Sea. Correlation coefficients computed for all element pairs indicate significant co-associations between concentrations of Zn and Mn as well as Mn and Fe in P. inflexus and the host organ, and for the pair Cu-Cr in the parasite. Based on both concentration and discrimination factors it is well documented that the metals studied, especially Fe, Mn and Zn are bioaccumulated in P. inflexus with respect to the host lung, showing significant inter-specimen variations.
