摘要
目的对膏方中农药残留和重金属残留进行监测,以期为膏方全面质量控制提供依据。方法采用GC法测定膏方中六六六(BHC,含α-BHC、β-BHC、γ-BHC、δ-BHC)、滴滴涕(DDT,含PP′-DDE、PP′-DDD、OP′-DDT、PP′-DDT)和五氯硝基苯(PCNB)的量;采用原子吸收光谱法测定Pb、Cd、As、Hg、Cu的量。结果 4批次膏方中的农药残留:BHC和DDT总量低于20 ng/g,PCNB的量低于10 ng/g;重金属残留:Pb的量低于0.5μg/g,Cd的量低于30 ng/g,As和Hg的量低于0.2μg/g,Cu的量低于2μg/g。结论膏方中农药残留量和重金属残留量均符合《中国药典》和欧盟规定的限量标准。
Objective To monitor the pesticide residues and heavy metal residues in the herbal paste and to provide the basis for the total quality control of the herbal paste.Methods The contents of benzene hexachloride（BHC,containing α-BHC,β-BHC,γ-BHC,and δ-BHC）,dichloro-diphenyl-trichloroethane（DDT,containing PP′-DDE,PP′-DDD,OP′-DDT,and PP′-DDT）,and pentachloronitrobenzene（PCNB） were determined by using the method of gas chromatography.The contents of Pb,Cd,As,Hg,and Cu were determined by using atomic absorption spectrometry.Results Pesticide residues in four batches of the herbal paste were as follows： The total BHC and DDT were less than 20 ng/g,and PCNB was less than 10 ng/g.The heavy metal residues were as follows： Pb was less than 0.5 μg/g,Cd was less than 30 ng/g,As and Hg were less than 0.2 μg/g,and Cu was less than 2 μg/g.Conclusion Pesticide residues and heavy metal residues in the herbal paste accord with the limit standards of Chinese Pharmacopoeia and the EU rules.
