Abstract:
OBJECTIVETo determine the residues of organochlorine pesticides and heavy metals in Radix Ophiopogonis and Ophiopogon japonicus.
METHODThe residues of 4 isomers of benzene hexa chloride (BHC) and 4 isomers of dichloro dipheny trichloroethane (DDT) were determined by gas chromatography. The contents of Pb, Cd, Cu, Cr, Hg and As were determined by ICP.
RESULTThe residues of organochlorine pesticides in Radix Ophiopogonis were lower than the permissible maximum limits of the Chinese national standard except hexachloride (BHC) in Radix Ophiopogonis from Cixi as well as Cu in soil of Luojiang.
CONCLUSIONThe enrichment capacity of Radix Ophiopogonis for (BHC) and Hg is higher. It is suggested that we should try to select herbs-growing soil for O. japonicus with a particular emphasis on the pesticides residues in soil.
