The content of mercury can be directly determined in the soil by solid mercury measurement instrument using pyrol-ysis atomic absorption spectrophotometry. It was showed that the method of correlation coefficient was 0.999 or higher, the de-tection limit was 0.01 ng, the linear range was 0.05~600 ng total mercury, precision was 6.0%~9.1%, accuracy was 0%~6.7%, and the recovery ranged from 95%to 107%.The method was simple, rapid, accurate, less interference and was suitable for the determination of soil bulk samples.
