ABSTRACT

Cadmium and lead levels were examined in blood serum and hair of 79 horses reared in 7 breeding centres. Blood and hair samples were collected twice a year: in summer and in winter. The concentration of the metals was determined with the ICP EAS emission spectrophotometer, model JY 24. Mean concentration of cadmium in the horses' blood serum in summer ranged from 0.027 to 0.07 micromole per litre, and in winter – from 0.003 to 0.049 micromole per litre. Mean concentration of this element in hair of horses was observed in the range 0.039–0.997 milligram per kilogram of fresh weight in summer, and 0.0–0.111 milligram per kilogram in winter. Average lead values found in blood serum were from 0.09 to 0.44 micromole per litre (summer) and from 0.06 to 0.17 micromole per litre (winter). Mean lead concentration recorded in the hair of horses ranged from 0.0 to 10.7 milligram per kilogram in summer and from 0.0 to 2.46 milligram per kilogram in winter. The study allows concluding that significantly
