Abstract
The migration of lead and cadmium from lacquered tableware was investigated. Seven samples of bowls and five samples of chopsticks were purchased on the market. The migration test was carried out with 4% acetic acid at 60 degrees C for 30 min. Lead and cadmium in the test solution was determined by flameless atomic absorption spectrometry. Release of lead was 3.4 and 4.4 ppb from two samples and release of cadmium was 1.3 ppb from one sample. Those samples were chopsticks coated with natural lacquer and colored with pattern. No other samples released lead and cadmium. Evapolation residue was less than 13 ppm in all samples.
