This study was carried out on plant samples taken from hazelnut gardens between Trabzon and Giresun provincial centers where hazelnut agriculture is made intensively. These gardens consist of ten different locations and three different altitudes at each location. Plant samples; It is composed of leaves, giraffes, hard crust and inner fruit (nuts), taken from the same garden. The heavy metals (Cr, Ni, Pb) in these samples were examined. The heavy metal contents in the samples were determined on the ICP-OES device by using the wet ashing technique. Cr 0.21 - 2.09 ppm, Ni 3.58 - 7.33 ppm, Pb 0.29 - 1.70 ppm in plant samples were determined. In the plant samples examined for heavy metal content, significant differences were found between the locations and between the arms, indicating that it has significant risks today and in the future.
