Investigation on Heavy Metal Pollution ın Uludag Fir Forests (Abies nordmanniana subsp. bornmülleriana MATTF) in the Bartın Region

Abstract

In this study carried out in pure Uludağ fir forests of Bartın-Ardıç district the change of amount ofheavy metals in both soil and needles of Uludag fir depending on altitude was investigated. For thisreason, experimental areas were established in three different altitude levels (1,000 m, 1,100 m and 1,200m) and changes of heavy metals were determined in the soil and Uludag fir needles. According to theresults obtained from this research, soil and plant contamination by heavy metals is increasing nowadayswhile the heavy metal (Pb, Zn, Ni, Cu, Cd, Mn, Cr and Fe) concentrations decreased with the increase inaltitude. The highest levels of Cd, Cr and Fe were found in the composite soil and needle of Uludag firadjacent to 1,000 m and other altitude levels. However, there are significant differences at the P
