[Objective]The study was to investigate residual regularity in tissues of layer after combined exposure to lead (Pb)and/or cadmium (Cd).[Method]Lead acetate (100 mg/L)and/or cadmium chloride (50 mg/L)were administered in drinking water to 120 individuals of 40-week-old hyline layers for 8 weeks.[Result]Compared with the Cd group,the Cd content in various tissues,except kidney and femur,in Cd+Pb group all increased,but the difference was not significant (P>0.05).The Cd contents in kidney and femur in Cd group were significantly higher than that in Cd+Pb group.Compared with the group Pb,the Pb contents in breast muscle and kidney in Cd+Pb group decreased significantly (P<0.05);the Pb contents in femur decreased extremely (P<0.01);while the Pb contents in leg muscle,heart and spleen increased significantly (P<0.05);the Pb contents in liver and glandular stomach were almost the same.Compared with the control group,the Cd content in various tissues in Pb group increased significantly (P<0.05);no significant changes were observed for Pb content in Cd group.[Conclusion]Deposit of Pb and Cd in poultry body had complex interaction.

[Objective] The study was to investigate the residual regularity in tissues of layer after combined exposure to lead (Pb) and / or cadmium (Cd). [Method] Lead acetate (100 mg / L) and / or cadmium chloride L) were administered in drinking water to 120 individuals of 40-week-old hyline layers for 8 weeks. [Result] Compared with Cd group, the Cd content in various tissues, except kidney and femur, in Cd + Pb group all increased , but the difference was not significant (P> 0.05) .The Cd contents in kidney and femur in Cd group were significantly higher than that in Cd + Pb group. Compared with the group Pb, the Pb contents in breast muscle and kidney in Cd The Pb contents in femur decreased extremely (P <0.01); while the Pb contents in leg muscle, heart and spleen increased significantly (P <0.05); Pb contents in liver and glandular stomach were almost the same. Compared with the control group, the Cd content in various tissues in Pb group increased significantly (P <0.0 5); no significant changes were observed for Pb content in Cd group. [Conclusion] Deposit of Pb and Cd in poultry body had complex interaction.
