Abstract

The occurrence of nickel from industrial emissions was determined in biological material of cattle slaughtered on agricultural farms Perin and Cestice in the fallout region of the metallurgical plant (ESIW) Kosice. In the period of 1997-1999 a total of 168 samples from 42 heads of cattle (muscle, heart, liver, kidney) were analysed for the presence of nickel by the atomic absorption spectrophotometer UNICAM SOLAR 939. Above-limit levels of nickel were determined in 15 of the 168 samples. The increased levels of nickel were recorded in the liver, heart and kidney. From the results obtained it follows that nickel is an ecologically important heavy metal in the observation area. We consider it necessary to implement ecological measures in the given area.

 

Key words: nickel, cattle, emissions, ecology.
