| Abstract: | Objective: To determine the heavy metal elements in Pinus plants and the soil. Method: The content of Pd,Cd,Hg,As in three Pinus plants and the soil was determined by atomic fluorescence photometry. Result: The correlative coefficients of the standard curves surpassed 0.999, with the recovery at 93.2%-103.6%, while the RSD was below 3.3%. The content of Pd,Cd and Hg was higher than the limited standard levels, the content As and the four heavy metal elements in soil were lower than the limited standard levels. Conclusion: The method is quick, simple with high sensitivity. It is a reliable method for the determination of the heavy metal elements in Pinus plants. |
