Elemental composition of Russula cyanoxantha along an urbanization gradient in Cluj-Napoca (Romania)

Abstract How far-reaching is the influence of the urban area over the mineral composition of the Russula cyanoxantha mushroom? We studied the metal uptake behavior of this fungus relying on the soil properties. We sampled mushroom and soil from six forests according to an urbanization gradient, and two city parks in Cluj-Napoca (Romania). The elements were quantified using inductively coupled plasma – optical emission spectroscopy (ICP-OES). The concentrations of some elements differed significantly (p
