The purpose of the work is to establish the characteristics of the accumulation of heavy metals of aboveground and underground organs in plant samples of 8 varieties of Narcissus hybridus and Camassia cusickii in the urbanized environment of the city of Ufa. The study of the elemental composition of the samples was carried out according to the method of quantitative chemical analysis ‘Determination of As, Pb, Cd, Sn, Cr, Cu, Fe, Mn and Ni in laboratory samples of food products and food raw materials by the atomic absorption method with electrothermal atomization’. It was found that the content of nickel, copper, cadmium, lead, magnesium, iron, chromium in all the samples studied does not exceed the standards specified in the State Pharmacopoeia of the Russian Federation (SP RF). The arsenic content exceeds the standards specified in the SP RF by 3.4 times. Revealed a high intensity of biological absorption of copper. It has been established that the concentrations of As, Cu, Pl, Mn, Fe in the aboveground organs are higher than in the underground part of plants; the ratio of the content of Ni, Cr, Cd in aboveground and underground organs is the same.
