An Investigation on the Possibility of Heavy Metal (Pb and Ni) Phytoremediation from Plant Artemisia Sieberi in Mohammadabad Waste Disposal Site in Ghazvin

This study was conducted in Mohammadabad waste disposal site in Ghazvin in order to determine the concentration of Ni and Pb in Artemisia sieberi and in region’s soil.

Three plots were selected. Ten random samples from root and shoot of the plant and also from the soil were collected. Two-way and one-way ANOVA were used to assess the differences of metal concentrations in roots and shoots of the plants, and in the soil of the plots, respectively. Duncan Test was applied to compare the average concentrations of metals in different plots.

The results revealed that the soil of the different plots does not have a significant difference in Ni and Pb concentrations. No significant difference was observed between the metal concentrations in roots and shoots of the plants. The mean concentration of lead in the A.sieberi aerial and root organs was 2.35 mgkg-1 and 3.19 mgkg-1, respectively, and for the nickel metal 3.14 mgkg-1 and 2.99 mgkg-1 respectively.

Bio concentration and transmission factors for Ni and Pb (TF=0.78; 0.81 and BCF=1.10; 0.33, respectively) suggested that A.sieberi is an appropriate plant to remove Pb from soil.
