摘要
本研究分析和评估山东省威海地区西洋参中重金属和有机氯农药残留情况,为山东西洋参的品质评价提供试验依据。采用湿法消解及HNO3-HClO4体系,用电感耦合等离子体发射光谱(ICP-OES)法测定西洋参中5种重金属元素的含量,气相色谱串联质谱(GC-MS)法测定样品中六氯苯(HCB)和五氯硝基苯(PCNB)2种有机氯的残留。威海地区12个乡镇23个村共42个采样点的西洋参中Cu检出频率为100%,含量范围为2.17~18.34 mg/kg;As检出率为76.19%,含量范围为0.02~0.53 mg/kg;Cd检出率为19.05%,含量范围为0.03~1.45mg/kg;Pb、Hg均未检出;5种重金属超标率为0%。样品中HCB、PCNB检出率为100%,含量范围分别为0.0036~0.0263 mg/kg和0.0121~0.2900 mg/kg,HCB均未超标,PCNB超标率为4.76%。42个采样点的西洋参样品重金属及农药残留的检出频率较高,重金属均未超出限量标准,2个采样点中有机氯含量超标。本试验为山东威海地区西洋参的质量控制提供数据支持。
The study analyzes and evaluates the residues of heavy metals and organochlorine pesticides in American ginseng in Weihai,Shandong Province,and provide a test basis for the quality evaluation of American ginseng.Wet digestion and HNO3-HClO4 system were used to determine the contents of five heavy metal elements in American ginseng by inductively coupled plasma emission spectroscopy(ICP-OES)and hexachloride in samples by gas chromatography tandem mass spectrometry(GC-MS)Benzene(HCB)and pentachloronit-robenzene(PCNB)two kinds of organic chlorine residues.The detection frequency of Cu in American ginseng at 42 sampling points in 12 towns and 23 villages in Weihai area was 100%,and the content range was 2.17~18.34 mg/kg;the detection rate of As was 76.19%,and the content range was 0.02~0.53 mg/kg;the detection rate of Cd was 19.05%,and the content range was 0.03~1.45 mg/kg;neither Pb nor Hg was detected;The excess rate of 5 heavy metals was 0.The detection rate of HCB and PCNB in the samples was 100%,and the content ranges were 0.0036~0.0263 mg/kg and 0.0121~0.2900 mg/kg respectively.HCB did not exceed the standard,and the PCNB exceeded the standard rate of 4.76%.The detection frequency of heavy metals and pesticide residues in American ginseng samples from 42 sampling points was relatively high.The heavy metals did not exceed the limit standard,and the organic chlorine content in 2 sampling points exceeded the standard.This experiment provides data support for the quality control of American ginseng medicinal materials in Weihai,Shandong.
