ABSTRACT: The purpose of this study was to examine concentrations of selected heavy metals in the liver and kidney of brown hares (Lepus europaeus). In addition, correlations between heavy metals and biochemical parameters in blood plasma were determined. The average concentrations of heavy metals (mmol/L) +/- SD were as follows: liver: Pb 0.221 +/- 0.189, Cd 0.160 +/- 0.140, Hg 0.021 +/- 0.030, kidney: Pb 0.115 +/- 0.125, Cd 1.570 +/- 1.103, Hg 0.030 +/- 0.053. The average concentrations of biochemical parameters in the blood plasma were as follows: Ca 3.16 mmol/L, P 2.19 mmol/L, Mg 1.40 mmol/L, Na 148.71 mmol/L, K 8.12 mmol/L, glucose 6.56 mmol/L, total proteins 56.49 g/L, urea 5.00 mmol/L, total lipids 1.40 g/L, bilirubin 3.97 micro mol/L, cholesterol 1.53 mmol/L, aspartate aminotransferase (AST) 6.06 micro kat/L and alanine aminotransferase (ALT) 1.94 micro kat/L. Average levels of hormones (ng/mL) were as follows: testosterone 2.94, androstendiol 0.13, estradiol 501.59, progesterone 6.63, oxytocin 328.60. Tissue analysis showed an accumulation of lead, cadmium and mercury in the liver and kidney of brown hares. There were no significant correlations between levels of heavy metals in liver, kidney, and biochemical parameters.

ABSTRACT: The content of cadmium and lead, as risk factors of environment, in liver and kidneys of wild animals as brown hare (Lepus europaeus), yellow-necked mouse (Apodemus flavicollis), wood mouse (Cleithrionomys glareolus), and red deer (Cervus elaphus) were studied. Samples were analyzed by the atomic absorption spectrophotometry method (AAS). The highest levels of cadmium were found in kidneys (0.213-2.387 mg/kg) of all animal species. The concentration of cadmium in liver was 0.032-0.258 mg/kg. The analysis of lead showed that the concentration of this element was higher in kidneys of yellow-necked mouse and wood mouse (0.503-0.780 mg/kg) than in liver (0.177-0.268 mg/kg). In brown hare and red deer a higher accumulation of lead in liver (0.221-1.904 mg/kg) in comparison with kidneys (0.115-0.561 mg/kg) is reported.

ABSTRACT: Concentrations of lead, cadmium, and mercury in liver and kidneys of brown hares in relation to season, age, and sex were investigated. Over a period of one year 74 hares, 36 males and 38 females were analyzed. The concentrations of lead and cadmium were analyzed by AAS and mercury was determined by mercury vapor technique. The median concentration of lead in liver as well as in kidney in relation to the season is the highest in winter period in comparison with spring, summer, and summer period (p < 0.001). The highest concentration of cadmium was found in winter, but the differences were not significant. In mercury, we report significantly higher (p < 0.001) median concentrations in liver (0.023 mg kg(-1)) as well as in kidney (0.068 mg kg(-1)) in winter period in comparison with all other observed periods. In relation to age the concentrations in lead and mercury in liver and kidney were very similar, without significant differences. In cadmium we report significantly higher concentrations in the liver as well as kidney in adult animals (0.154 and 1.521 mg kg(-1)) in comparison with juvenile animals (0.048 and 0.582 mg kg(-1), respectively). In comparison of the female and male brown hares we found significantly higher (p < 0.05) median concentration of lead in the liver of males (0.216 mg kg(-1)) than in females (0.127 mg kg(-1)) and the level of cadmium is significantly higher (p < 0.001) in females (1.464 mg kg(-1) than in male brown hares (1.384 mg kg(-1)).
