This work studied trace elements in the paleo-sediment of the Yellow River of Wuzhi, Jiaozuo, Henan Province, using the flame atomic absorption spectrometry and atomic fluorescence spectrometry to analyze the concentration of trace elements (Cu、Ni、Mn、Zn、Pb、Cr、Fe、As). The concentrations of the eight trace elements in the paleo-sediment of the Yellow River ranged between 6.42 and 28.35 mg·kg-1 (mean 15.09 mg·kg-1), 13.69 and 39.24 mg·kg-1 (21.31 mg·kg-1), 158.8 and 338.65 mg·kg-1 (219.56 mg·kg-1), 178.25 and 309.75 mg·kg-1 (239.49 mg·kg-1), 14.16 and 27.19 mg·kg-1 (20.22 mg·kg-1), 27.25 and 67.71 mg·kg-1 (37.84 mg·kg-1), 17830 and 34080 mg·kg-1 (25942 mg·kg-1) and 26.315 and 532.01 mg·kg-1 (141.71 mg·kg-1), respectively. The results showed that the impact of human activities is one of the main factors, especially the destruction of natural vegetation of the middle reaches of Loess Plateau in the Qin and Han Dynasties and the development of industry and agriculture.特集 : 「資源、新エネルギー、環境、防災研究国際セミナー
