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.
