1998
Stranai, I. (Slovak Agricultural Univ., Nitra (Slovak Republic))
From 1993-1995 tissues from ten species of fish, present practically for the entire length of the Nitra river (western Slovak Republic), from kilometer 160 to its outfall into the Vah river, were analyzed. Contents of lead, cadmium and chromium in muscles, liver and kidney were defined. The lowest values were found in muscles. These values, for lead, cadmium and chromium, which are accumulated above all in entrails, do not overstep hygienic limits. However, in cases of chub, giebel and partially carp, the muscles are also contaminated with cadmium, whose concentration in some samples exceeded the standard limit. In samples from entrails chromium overstepped its permitted limit in the majority of species, with the exception of rapacious carp, pike-perch and wels
