The results of the complex histologic biochemical research of Cucumis sativus L. seedlings, obtained when grown on copper and cadmium contaminated soils. Histochemical method allows to reveal the mechanism of heavy metal distribution in seedling tissues and to assess their damage degree, even in the apparent external wellbeing. Biochemical indices such as catalase activity, chlorophyll and sucrose content, decrease significantly due to metabolic process inhibition in the seedling tissues.
