To determine five kinds of heavy metal content in Bo Angelica dahurica, the five heavy metal were directly detected by microwave-ICP-MS. This test method had a good linear relationship, the precision test of RSD was in the range of 1. 99%~4. 89%, the repeatability test of RSD was in the range of 1. 31%~5. 09%, the average recovery rates were ranged from 83. 95%~103. 13%; The twelve plots in Bozhou City of Bo Angelica dahurica of plumbum ( Pb ) , cadmium ( Cd) , mercury ( Hg) , arsenium ( As) and copper ( Cu) shall not exceed the standard of heavy metal content. This method can accurately recommend heavy metals content of Bo Angelica dahurica, as well as recommend Bo Angelica dahurica detection and safely evaluation provided a reliable technical method.
