| Abstract: | Based on the Chinese national standards(GB/T 5009.12-2003 Determination of lead in foods,and GB 2762-2005 Maximum levels of comtaminants in foods),lead contents in foods were determined with graphite furnace atomic absorption spectrometers made in China and abroad,and the results were compared.It has been shown that the measurement accuracy and precision of the instruments made in China can meet the requirements of the Chinese national standards for the determination of lead in foods. |
