摘　　要：研究黑龙江道地药材火麻仁中的有机氯农药和重金属的残留水平。从黑龙江省内4个片区共采集10批样品,我国南方不同产地采集12批样品,采用电感耦合等离子体质谱法进行重金属的测定,采用气相色谱-质谱法进行农药残留的测定,参照2020版《中国药典》四部通则,对中药材中有机氯农药和重金属的残留进行风险评估。有机氯农药在南方不同产地采集10批样品有所检出;在重金属残留方面,参考《中国药典》对重金属一般限量标准的规定,在南方不同产地采集7批样品超标,其余南方所产火麻仁虽然重金属含量均不超过国标限量标准,但是重金属含量相对于黑龙江省产火麻仁均有较大差异,仍有健康风险。为系统全面精准评价不同产地的火麻仁的质量奠定基础、提供科学依据。This study investigates the residual levels of organochlorine pesticides and heavy metals in hemp seed,an authentic medicine in Heilongjiang Province,along with its health risk assessment.Ten batches of samples were collected from four areas in Heilongjiang Province,while additional 12 batches were obtained from various producing areas in southern China.Heavy metals were determined by inductively coupled plasma mass spectrometry,and pesticide residues were determined by gas chromatography-mass spectrometry.According to the four general principles outline in China Pharmacopoeia(2020 edition),the risk assessment of organochlorine pesticides and heavy metals residues in Chinese herbal medicines was carried out.Organochlorine pesticides were detected in all ten batches of samples collected from different producing areas in southern China.In terms of heavy metal residue,seven batches of samples exceeded the general limit standard set by China Pharmacopoeia.Although the heavy metal content in the remaining hemp seeds from the south did not exceed the national limit standard,it significantly differed from that of hemp seeds produced in Heilongjiang Province,indicating health risks.This study aims to provide a solid foundation and scientific evidence for a comprehensive and precise evaluation of the quality of hemp seeds from different origins.
