| 摘 要： | In this study, we applied synchrotron radiation X-ray fluorescence technique （SR-XRF） to investigate the heavy metals including Hg and Pb in a few single strands of pinnule of the outermost wing feather of snow petrel （Pagodroma Nivea） collected in the Antarctic. The microscopic distributions of Hg and Pb along with the strand of pinnule show significant variation and the types of distribution are different for pinules, suggesting that external contamination may have an important impact on the levels of Hg and Pb, rather than reflecting levels in the blood during feather formation. This should be taken into account in future monitoring studies. The sources of Hg and Pb detected in the feather were also discussed. Using feathers of snow petrel to investigate the springtime mercury depletion events （MDEs） in the Antarctic were proposed.
