Determination method for total mercury in paddy and products directly by mercury analyzer was established. Meanwhile, the total mercury content in 20 portions of paddy sample had been investigated by the method. The results indicated that agood linearity was observed within a range from 0～400ng，theminimum detection limit was 0.1μg/kg, theminimum quantitative limit was 1μg/kg, the relative standard deviation (RSD) was less than 2.0%. The results of determining national reference material, Liaoning rice (GBW10043) and Hunan rice(GBW10045), were all in the scope of standard values. Compared with national method, the result has no remarkable difference. The total mercury in both paddy and products were all below the national standard limit. The mercury were main concentrated in rice, secondly in the rice bran, while nearly none in rice husk.
