Abstract
In this work, the concentration of five non-essential (Cr, As, Cd, Pb and Hg) and three essential elements (Cu, Zn and Se) in five different species from the genus Lactarius collected from Southern Spain and Northern Morocco were determined by ICP-MS after a block acid digestion. Zn was found to be the major element in all the studied samples, followed by Cu and Cr in almost all the cases. The data obtained from the Health Risk Index (HRI) assessment suggested that As content in L. semisanguifluus and L. deliciosus collected from different locations in Granada and Cadiz provinces (Spain) may pose a risk to human health. The comparison between the Daily Intake of Metals (DIM) and the Recommended Dietary Allowance (RDA) indicated that the consumption of the studied mushrooms only covers a small percentage of the daily requirements of Cu, Zn and Se.
