Abstract: The paper presents the results of environmental and geochemical researches of soil and plant covers in Pushkin city – a unique cultural and historical center, suburb of Saint-Petersburg (Russia). The investigations of elements-pollutants (radionuclides (14С, 3Н), heavy metals, arsenium, etc.) and plant nutrient chemical elements (P, K, Ca), showed the significant dependence between distribution of elements in soils and plants. High degree of correlation is common for distribution of radionuclides and heavy metals. Moreover, soils and vegetation in areas contaminated with heavy metals and radionuclides are as a rule depleted in nutrients. The obtained results were supported by bioindication researches.
