| concentrations of zn, mn, cu and cd in different tissues of perch (perca fluviatilis) and in perch intestinal parasite (acanthocephalus lucii) from the stream near prague (czech republic). | we monitored concentrations of cd, cu, mn and zn in acantocephalan parasites (acanthocephalus lucii) and its final host (perca fluviatilis). the concentrations in parasites were found to be significantly higher than those found in the muscle, gonads and liver of fish host. the bioaccumulation factor values (bf=c(parasite)/c(host muscle)) were 194, 24.4, 2.2 and 4.7 for cd, cu, mn and zn, respectively. this suggests a benefit for the host due to the high accumulation of toxic cadmium. | 2011 | 22118835 |
| intestinal parasite acanthocephalus lucii (acanthocephala) from european perch (perca fluviatilis) as a bioindicator for lead pollution in the stream "jevanský potok" near prague, czech republic. | lead concentrations in the tissues of perch and its parasites were determined as mg/kg dw. lead was found at higher concentrations in the acanthocephalans (11.56) than in different tissues (liver, gonads and muscle with skin and bone) of perch. with respect to fish tissues, the highest concentrations of lead were present in the liver (1.24), followed by the gonads (0.57) whereas the lowest concentrations were in the muscle with skin and bone (0.21). the bioconcentration factors for lead indicate ... | 2011 | 21301806 |
