摘要：Introduction and objective. Research focused on the monitoring of selected heavy metals in ewes?blood. Concentrationsof selected toxic elements, lead, cadmium and zinc, in ewes living near an environmentally-loaded area, concerned 15 ewes(aged 3? years) in good physical condition, during the spring of 2014 and 2015 in the eastern part of Slovakia. The aimof the research was to determine the concentration of selected heavy metals and state the correlations of selected heavymetals in ewes?blood.Materials and method. Within the period of 2 years, 15 ewe were evaluated. Ewes?blood samples were collected twiceduring the spring season from a farm located in area Spi? eastern Slovakia, and then analysed for heavy metal contents. Inthe area under investigation, contamination with heavy metals was assumed as a result of intensive agricultural developmentand former mining activities. The level of selected heavy metals in the experimental group of animal blood was determinedusing an optical spectrophotometry.Results. Statistical analyses were carried out using the Statistica programme. The significant differences between meanswere calculated by the statistical method of the non-parametric Mann-Whitney磗 U test. The statistical test experimentalgroup of ewes in 2014 and 2015 confirmed the presence of selected heavy metals in ewes. The measured values of Cd(P=0.0003), Pb (P=0.0200) and Zn (P=0.0018) showed significant differences when comparing the years 2014 and 2015.Conclusion. The obtained and analysed blood samples confirmed the presence of selected heavy metals in ewes fromarea of Spi?in eastern Slovakia, which belongs the sub-region or is among the localities environmentally burdened. Theconclusions are centred on the population抯 interest and concern for the environment, as well as on the preoccupationwith factors that affect the satisfaction of basic needs, the local agricultural development and former mining activities.
