Heavy metal concentrations in tapeworms Diploposthe leavis and Microsomacanthus compressa parasitizing aquatic birds.
Original language description
Two parasite-host systems tapeworms Diploposthe laevis and Microsomacanthus compressa vs. Final hosts aquatic birds Aythya terina and A. nyroca were analysed by atomic absorption spectrometry for heavy metal (Pb, Cd, Cr, Ni) concentrations and compared with those found in muscles and liver of the final hosts.The ability of adult tapeworm to accumulate different concentrations was greater than that of their hosts´ tissues. The value ratios of the heavy metal concentration in D. laevis, (2.0-3.6) and M. compresa (2.3-22.3),respectively were higher than those in their final hosts´ tissues. The percentage proportion rank of individual heavy metals in the combined sample of strobilae of the above tapeworm species and in the sample of their hosts tissues indicates the highest proportion in Pb (40.6-57.9 %) followed by that in Ni, Cr and Cd, expect for the highest proportion of Cr in the liver of A. nyroca, followed by successively decreasing concentrations of Pb, Ni and Cd.
