in locality Olšanské pole, which was even exceeding the hygienic<br />

limit determining the soil sanitation (1.9 to 3.8-fold of<br />

value C 10 mg Hg kg –1 ). Similarly the extremely high content<br />

of Hg was determined in Poráč, where the 3.2-fold higher<br />

exceeding of this limit value was determined. The contamination<br />

of soil by Hg was obvious also in localities: Pod horky,<br />

Zemkovské (Markušovce) and na stráni (Matejovce because<br />

of the exceeding of limit value B (2 mg Hg kg –1 ) for the soil<br />

contamination at 4.65-fold. Similarly the soil contamination<br />

by As was proved in Markušovce (locality Olšanské pole),<br />

where the limit value B (30 mg As kg –1 ) was exceeded 1.45fold<br />

and Poráč (locality Pasienky) with 1.06-fold In Poráč the<br />

soil contamination by Cu was evident (1.15-fold of limit B).<br />

Conclusions<br />

The residual soil burden by heavy metals and potential<br />

follow contamination of the food chain in observed areas presents<br />

the potential risk for the human health. Therefore it is<br />

important to monitor the risk metal contents as in soils as in<br />

agricultural plants and in case that it is necessary to realise<br />

s520<br />

the remedy for the inhibition of the risk heavy metal input<br />

into the human food chain.<br />
