We collected 51 feather samples from the breasts, tails and wings of Oriental White Storks（Ciconia boyciana）and Siberian White Cranes（Grus leucogeranus）at Hefei Wild Animal Park in May, 2007. Environment-Determination of methylmercury-Gas chromatography was used to determine the residues of op’-DDT, pp’-DDD, pp’-DDE, pp’-DDT, α-BHC, β- BHC, γ- BHC, δ- BHC and Hexachlorobenzene. The results showed that pp’-DDD, pp’-DDE, pp’-DDT, β-BHC, δ-BHC were detected in feathers of both Oriental White Storks and Siberian White Cranes, in which pp’-DDD had the greatest proportion, and reached 0.8936, 0.8353 and 0.7516 μg/g (dry weight) respectively in the breast contour feathers, pluma and tail feathers of Oriental White Storks. The residues were 0.5685, 0.5077 and 0.4657 μg/g (dry weight) in the feathers of Siberian White Cranes. There was not a significant difference in the residues of pp’-DDD and pp’-DDT in the breast contour feathers, pluma and tail feathers between both birds, but residues of pp’-DDD in the breast contour feathers and tail feathers of the Oriental White Stork was significantly higher than that of the Siberian White Crane.
