摘要
通过监测吉林省2001～2004年6个地区食品中铅、镉含量,了解铅、镉的污染状况,并提出铅、镉可能的污染来源。按照国家标准方法GB T5009对样品进行前处理,采用石墨炉原子吸收光谱法检测铅、镉含量。2001年～2004年共监测13类917份食品中铅、镉含量,铅超标率为9.49%,镉超标率在6.24%。结果显示目前食品中铅、镉污染不严重,但由于各类食品中铅、镉都有检出,说明存在不同程度的积累,对人体健康存在潜在的威胁。
Through monitoring content of lead and cadmium in foods of six cities in Jilin Province, situation of lead and cadmium pollution and their possible sources was realized. Pb and Cd contents in foods were determined by graphite furnace atomic absorption spectrometry after pre-treatment according to national standard method. 917 samples of 13 kinds of foodstuffs were monitored during the period from 2001 to 2004. it was found that Pb in 9. 49% of samples and Cd in 6.24% of samples were over standard. Results showed that pollution of lead and cadmium in Jilin not very serious during that period. However, lead and cadmium detected in all kinds of foodstuffs suggest accumulation and potential harmful impact on human heahh may be existing.
