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.
