[Residues analysis of pesticides and heavy metals in Whitmania pigra and its breeding base].
OBJECTIVE
To give a reference to the safe and standardized production of Whitmania pigra, through the comparative research on residues of heavy metals and pesticide in W. pigra, breeding base soil and breeding water .


METHODS
Residues of heavy metals and pesticide in W. Pigra, soil and water were determined by atomic absorption spectrophotometers, atomic fluorescence spectrophotometers and GC-ECD.


CONCLUSIONS
With the exclusion of Pb residue, the residues of HCH, DDT and other heavy metals in W. pigra, soil and water in breding base met the requirements of the national standards. We suggest that the residues limits of animal drugs like W. pigra should be listed in a separate category when the national standards are revised in the fature.
