- Abstract: In order to evaluate the heavy metal potential pollution of soil and medicinal materials in main producing area of Phellodendron amurense, we collected 32 soil samples and 32 herb samples from northeast and north of China covering four provinces. In this study, the detection of heavy metal contents was conducted by ICP emission spectroscopy and atomic fluorescence spectrometry. The results showed that the soil from all areas of Ph amurense generally reached the national standard. As, Hg, Cr, Cd, Pb and Cu content of herb samples met the requirtment of the national standard except Hg content exceeding standard slight in a few samples. The reason of excessive Hg was the ability of Hg accumulation in Ph. amurense and atmospheric environment was polluted. So, national standard and Good Agricultural Practice (GAP) must be carried out severely in Ph. amurense resources production.
