We studied the level of mercury in the kidneys, liver and muscle tissue in breeding hens and in 7-day-old chicks hatched from the eggs of experimental hens. Mercury in the form of phenyl mercury chloride was applied to the feed at the dose of 5 ppm and 30 ppm. In hens in both experimental groups the highest mercury level was found in the kidney, a high level in the liver and the lowest in the muscle tissue. The same tendency for mercury to accumulate was found in the organs of 7-day-old chicks hatched from experimental hens. The increased dose of mercury applied to the hens in the second group was reflected in a mild increase in mercury level in the kidneys, in the double increase in the muscle tissue and in the decrease in the liver. A higher increase in mercury level was observed in 7-day-old offspring after 4 and 8 weeks of experiment. Statistically significant differences in the liver and in the kidneys were observed between the control and the 2nd group (P < 0.05) and between the 1st and 2nd experimental group (P < 0.05). The longer the experiment lasted, the more the mercury level decreased in the chick liver and muscles and increased in their kidneys.
