摘要: 采集南京市17个农贸市场、6个超市的芦蒿样品共37个,用原子吸收光谱法和原子荧光光谱法测定芦蒿中铅(Pb)、铬(Cr)、汞(Hg)、砷(As)的含量。结果表明:芦蒿中铅含量为0.35±0.10mg/kg,铬含量为0.22±0.10mg/kg,汞含量为0.01mg/kg,砷含量未检出。对照国家食品卫生标准,97.3%的芦蒿样品中铅含量超出食品中铅限量卫生标准,芦蒿样品中铬、汞、砷含量在限量卫生标准以内,芦蒿中铅的来源可能是产地环境质量的原因。

Abstract: The concentration of heavy metals including plumbum (Pb),chromium (Cr), hydrargyrum (Hg) and arsenic (As) were determined on Artemisia seleirgensis Turoz collected from 10 terminal markets and 6 super markets by atomic absorption spectrophotometer and atomic fluorescent spectrophotometer method. The results showed that the concentration of Pb and Cr were 0.35±0.10mg/kg and 0.22±0.10mg/kg, respectively. However, Hg and As were not detected except two samples at 0. 01mg/kg. Compared with limits of National Food Health Standards of Pb<0.20mg/kg, Cr<0.50mg/kg, Hg<0.01 mg/kg and As<0.50mg/kg, the concentration of Pb of 97.3% samples were unqualified. The pollution of the environment may be responsible for high level of Pb in Artemisia seleirgensis Turoz.
