摘要

Forty female chickens were allocated to four groups of ten birds each. The control group (K) was fed a basal diet without supplementation. The second control group received a basal diet with humic acid (HA) at a dose of 0.5 g per chicken/day. The first experimental group was fed the basal diet with methylmercury (MeHg) at a dose of 0.02 mg per chicken/day and the group of chickens MeHg + HA received 0.5 g HA per chicken/day. After slaughter, mercury levels were assessed in liver, kidney, brain and muscle tissue samples. After 10-day treatment of the chickens with MeHg, significantly increased (P < 0.001) Hg concentrations were detected in all examined tissues in comparison with the groups K and HA. The average concentrations in liver, kidneys, brain and muscle tissues were 424, 398, 81.6 and 79.2 mu g Hg/kg, respectively. After concurrent treatment with HA and MeHg, Hg concentrations were lower by 20.6%, 23.8%, 23.0% and 18.6% in liver, kidneys, brain and muscle tissues (P < 0.001). Biological accumulation of Hg was 25.5% and 20.4% in MeHg and MeHg + HA groups, respectively.
