Heavy metals in the mountain streams

A heavy metal representing a subset of elements that exhibit metallic properties, which would mainly include the transition metals, some metalloids, lanthanoids, and actinides. There have been proposed many different definitions of the term “heavy metals”. Some of them were based on density, some on atomic number or atomic weight. Also some definitions were founded on toxicity or other chemical properties. The elements in heavy metals group are miscellaneous. But latest times, the occurrence of heavy metals were dramatically changed in the nature. In many places the concentration of heavy metals was increased. It was caused by thoughtless human activity, i.e. toxic pollution as consequence of mining natural resources. It was confirmed, high concentration of these elements in nature has serious impact on the living organisms, so it is still necessary to study this theme, and of course find the solutions which can help to eliminate them from nature. In contrast to the High Tatra streams, very little published information are available on the biota and chemical properties of the streams in the West Tatra. In view of the need to increase our knowledge in this area, the Institute of Fishery Research and Hydrobiology organized a limnological investigation of the West Tatra lakes in 1988-1990.
