Direct determination of mercury in tobacco and tobacco production by cold atomic absorption was discussed.The working conditions of the instrument were optimized.The relation rate was greater than or equal to 0.9992. Detection limit (3S/N) found was 0.04 ng.Recovery of the method was tested by the standard addition method, and the results obtained were in the range of 96.0%to 102%, better than other methods.The values of RSD was less than 6%. Mercury content in tobacco and tobacco products was 0.036~0.120 μg/g.
