摘要
目的:建立6个不同药店穿心莲中4种重金属元素的检测方法,并对其含量水平和健康风险进行初步评价。方法:采用微波消解—原子吸收光谱法定量分析广州市6个不同药店穿心莲中铅、镉、铜、铬等4种重金属元素的含量。结果:健民(利众店)和采芝林(神农轩分店)的穿心莲样品Pb超标,而Cd元素除采芝林(南方分店)的穿心莲合格之外,其它均超标。从重金属总量来看,健民(利众店)的穿心莲超标较严重。结论:从健康风险指数来看,健民(利众店)和采芝林(神农轩分店)穿心莲的含铅量、采芝林(神农轩分店)和康美药店售穿心莲的含镉量及健民(利众店)的穿心莲含铬量,都可能会对人体健康产生一定风险,应该予以重视。
Objective： To establish the method for determination of four heavy metal elements in herba andrographitis from six drugstores in Guangzhou city,and discuss it＇s concentration and health risk assessment.Methods： Four heavy metal elements in herba andrographitis from six drugstores were measured by microwave digestion-atomic absorption spectrometry method.Results： The concentrations of Pb in herba andrographitis from jianmin and caizhilin（shennongxuan branch store） drugstores were both found higher than national standard.The concentrations of Cd were all beyond national standard except for caizhilin south branch store.The sum Concentration of four heavy metal elements from Jianmin drugstore was obvious higher than other drugstores.Conclusion： The Risk Index showed that the concentrations of Pb from Jianmin and Caizhilin（Shennongxuan branch store） drugstores,the concentrations of Cd from Caizhilin（Shennongxuan branch store） and Kangmei drugstores,and the concentrations of Cr from Jianmin drugstore will possibly produce health risk of adult person.We should pay much attention to this situation.
