Nickel content in plants and soil in the area of the protected natural resource “Avala” - Belgrade

The purpose of this research is above all focused on the aim of determining the load of ecosystem or rather soil and plants with the heavy metal Ni and the level of accummulation in this area so that on the basis of the obtained results adequate protection measures could be timely taken. The research of nickel (Ni) content in the leaves of herbs and woody plants growing under urban conditions in comparison with the nickel concentrations in the plant leaves in the protected natural resource “Avala” (16 km away from Belgrade) indicates that the recorded values of nickel concentrations by locations are statistically significantly different and range from A to F on locations 1, 2 and 3 while on location 4 in urban conditions the values range from A to B in accordance with Duncan’s Test.
