Abstract

The paper presents the results of an analysis of the content of heavy metals (Pb, Cd, Zn, Ni, Cu and Fe) in a leaf of green salad from six locations which gravitate towards the city of Zenica. After sampling from the defined locations, samples of green salad were prepared for analysis in the laboratory of the Faculty of Metallurgy, by dry digestion procedure. Analysis of heavy metals was performed on device "Atomic Absorption Spectrophotometer, PerkinElmer AAnalyst 800", using two techniques, flame technique and technique of graphite cuvette (TGHA). The results show that the concentration of lead in leaf of green salad from one location exceeds the maximum allowable concentration (MDK) defined by the national regulations of BiH. Concentrations of other analyzed heavy metals in the leaf of green salad are below MDK at all defined locations.
