The examinations of the content of lead and cadmium in the liver and kidneys were carried out on 237 foxes which included 110 females and 127 males. The level of the tested metals varried greatly. The maximum content exceeded the minimal standart 89 times in the liver and as much as 123 times in kidneys, while the maximum content of cadmium exceeded the minimal standard by 43 times in the liver and 79 times in kidneys. It was noted that an average concentration of lead in males was greater than in females: 0.142 and 0.126 mg/kg in the liver, and 0.147 and 0.127 mg/kg in kidneys, respectively. The average concentration of cadmium in the liver was identical for both sexes, i.e. 0.036 mg/kg. However, the level of cadmium in the kidneys of males was higher (0.113 mg/kg) than in females (0.093 mg/kg). The highest concentration of the tested elements was found in foxes with reproductive disturbances.

The content of iron, copper and manganese was tested in 237 foxes, including 110 females and 127 males. The level of the elements varied greatly in the liver and in the kidneys according to the sex of the foxes. The average concentration of iron and copper was much higher in the liver of males than that in females and also higher in the kidneys of females compared with that in males. The average concentration of manganese in the kidneys of foxes did not vary considerably in either sex. On the other hand, it was notably higher in the liver of males than in females. The average level of iron, copper and manganese was significantly higher in the liver than in the kidneys of foxes independent of sex.

During the last 6 years 6491 pigs and 1700 cattle were examined for antibiotic residues. The samples of the kidneys, livers and muscles were taken by veterinary sanitary inspectors. Examinations were done by an agar disc method using Bacillus subtilis ATCC 6633 spores as the indicator bacterium. Positive results were confirmed by a cylinder-agar plate method. Antibiotic residues were detected in 42 pigs (0.65%) and 3 cows (0.18%). Streptomycin was found in 33 pigs, oxytetracycline in 9 pigs and 2 cows and penicillin only in one cow. The residues of antibiotics were found in the kidneys and livers but not in muscles. Residues of antibiotics can be assumed as sporadic. The may result from a therapeutic use of antibiotics and inobservance of their withdrawal time.
