[Comparative study on pesticide and heavy metal residuals of four cultivars of Chrysanthemum morifolium].
OBJECTIVE
To study organochlorine pesticide and heavy metal residuals of Chrysanthemum morifolium.


METHODS
The contents of organochlorine pesticide residuals was determined by chromatography, Cu, Pb, Cd was determined by AAS, and As, Hg was determined by AFS.


CONCLUSIONS
The contents of organochlorine pesticide and heavy metals residuals are up to "Green Trade Standards of Importing & Exporting Medicinal plants & Preprations" (MOFTEC, 2001), but the contents are different among four cultivars clearly.
