The comparative analysis of two forms of heavy metal in soils of the Primorsky Krai Nature Reserves in the article. Reveals the importance of choice the assess criteria of heavy metals the content in the soil. Analysis the elemental composition of the Nature Reserves soils for the possibility of using these areas as a background was held in this research. The obtained results confirm that, for the purpose of soil-ecological monitoring is the most appropriate definition of «pseudo gross» forms of heavy metals and their comparison with the established maximum permissible concentrations (MPC). The content of total forms of heavy metals should be compared to the сlark value, however, these values cannot be used to establish the level of contamination, because in the process of migration involved only part of the elements of the gross and only part of the elements to be in plant-available form.
