Concentrations of some heavy metals in the Parvitaenia ardeolae (Cestoda) and in the host Ardea purpurea.
Original language description
Using the atomic absorption spectrophotometry, the content of 4 heavy metals (Cd, Pb, Ni, Cr), in the strobila of gravid tapeworm specimens Parvitaenia arddeolae Burt, 1940 (Dilepididae), were determined. The concentrations of the same HMs were also determined in the liver and muscle of the definitive host Ardea purpurea (Ciconiiformes). In the tapeworm biomass the following values of HMs (in 100% dry matter in mg.kg) were found: Cd= 0.42?0.06, Pb= 6.21?0.98, Ni= 1.43?0.31, Cr 0.51?0.10. In the hosts liver tissues: Cd= 0.42?0.06, Pb= 0.55?0.03, Ni= 0.01?0.03 and Cr= 0.03?0.01. In the muscle of the same host: Cd= 0.02?0.01, Pb= 0.77?0.08, Ni= 0.05?0.01 and Cr 0.07?0.02. Generally, the accumulation of 4 HMs in the P. ardeolae - gravid specimens were higher than in the liver tissue or muscles of the definitive host A. purpurea. The highes value was determined in the case of Pb, the minor in Cd.
