摘要：为了解北京市中小学周边食品店中出售的儿童小食品中重金属污染情况,采用原子吸收光谱法,测定了31种儿童小食品中的Cu、Zn、Pb、Cd、Cr的含量。结果显示,儿童小食品中对人体有害的铅、镉检出率分别为95%和60%～75%,除镉、铬的合格率分别为75%～87.5%和75%～100%,其他元素合格率均为100%。其中镉污染较重,大于1/2标准值及超标的样品比例占45%～75%,儿童小食品在一定程度上受到了重金属的污染,除镉元素外,大部分元素含量在国家标准值内,以低于1/2国家标准值为多。这些小食品受镉、铅、铬污染虽不严重,但普遍存在。镉污染较铅、铬污染相对严重,应给予一定重视。
In order to investigate the heavy metals pollution in small packs of ready food for children which were sold around the primary and junior high school in Beijing city, we measured the contents of copper （Cu）, zinc （Zn）, lead （Pb）, cadmium （Cd）, chromium （Cr） in 31 kinds of packed food by Atomic absorption spectrometry. The results showed that the detection rates of Pb and Cd in tested food were 95% and 60%-75%, and content of Cd in 12.5%-25% of tested food had exceeded the national standards, meanwhile the content of Cr in some ready food also had exceeded standards. Cd pollution was more serious than other heavy metal, it existed in 45%-75% of the tested food with the content over 1/2 standard or standard. Although the heavy metal pollution in our tested food is not serious except for Cd, most heavy metals contents were lower than 1/2 national standard, the fact that most of heavy metal can be checked out should be paid attention.
