[Objective] To determine content of heavy metal in wild Oenanthe javanica (Blume) DC and its growing soil, so as to analyze the relationship between the two. [Method] The content of heavy metal in tested samples collected from Taihu located in Suzhou and Wuxi was determined by ICP, followed by the correlation analysis. [Result] Among soil samples, only Pb content reached the rank 2 soil requirement ruled in Environmental Quality Standard for Soils (GB15618-1995). Contents of Cd, Cr, As and Ni in growing soils were all out of limits apart from Cu, Zn and Pb. Cd, Cr, As, Ni and Pb were not detected in wild Oenanthe javanica (Blume) DC. Content of Mn in stems and leaves showed a significant correlation with that in soil (-0.96). [Conclusion] The soil of Taihu was polluted slightly by heavy metal, but the wild Oenanthe javanica (Blume) DC was edible.
