Abstract:
This study was aimed to detect the heavy metal residues of medicinal leeches, in order to understand the current market circulation situation of medicinal leeches, and to analyze possible factors which may cause heavy metal pollution, and to provide references for the standardized safe cultivation of medicinal leeches. Inductively coupled plasma mass spectrometry (ICP-MS) technique was applied to detect heavy metal residues in medicinal leeches. The results showed that medicinal leech samples tested for heavy metal content severely exceeded the standard, which caused a great threat to the safety of medication. It was conclude that more attentions should be paid on factors for causing heavy metal accumulation within medicinal leeches during the breeding process. The related department should also list safety limits explicitly and separately for animal drugs such as medicinal leech during the development of quality standards of Chinese materia medica.
