Abstract： A method for the determination of mercury in wheat food by atomic fluorescence spectrometry was developed. The results showed that the correlation coefficient （R2） of the method was 0.998 648， the detection limit was 2.00 μg·kg-1， the recoveries were 97.33% to 103.33%， and the RSD value was lower than 4.00%. The results of this method are accurate and stable， and can be applied to the detection of mercury content in food.
