以8种果蔬（9种样品）为研究对象，采用湿法消解，建立了ICP—AES同时检测铜、钴、镍、铬、镉和铅六种重金属元素含量的测定方法。在最优条件下，实验结果表明：Cu、Pb、Ni、Cr、Cd和Co的检出限分别为0．0015μg·mL^-1、0．024μg·mL^-1、0．0042μg·mL^-1、0．0033txg·mL^-1、0．0006μg·mL^-1和0．0021Ixg·mL^-1，相对标准偏差介于0．12％^-110．29％之间，加标回收实验中回收率均介于89．4％-108．6％之间（土豆中Ni的回收率为123．7％）。根据国家食品卫生标准中的果蔬类标准，通过分析得出，Cr、Cd两种重金属元素污染比较严重，对居民的身体健康存在潜在的威胁。

Eight kinds of fruits and vegetables ( nine kinds of sample) as the research objects, using wet digestion, a method of simultaneous detection of the concentration of six heavy elements Cu, Pb, Ni, Cr, Cd, and Co using ICP-AES was established. Under optimal conditions, the experimental results showed that the detection limits of Cu, Pb, Ni, Cr, Cd and Co were 0. 0015 μg · mL^-1 , 0. 024 μg - mL^-1 , 0. 0042 μg · mL^-1 , 0. 0033 μg · mL^-1 , 0. 0006 μg · mL-land 0. 0021 μg · mL^-1 respectively. Relative standard deviation was between 0. 12% and 10. 29% , recoveries ranged from 89.4% to 108.6% ( the recovery of Ni in potatoes was 123.7% ). According to the national food hygiene standards in the fruit and vegetable standards, the results showed that pollution was more serious of the two heavy metal el- ements Cr and Cd, causing a potential threat to the physical health of the residents.
