Introduction:
Soil pollution by heavy metals in the soil due to long-term sustainability and ecologically harmful effects, has become an environmental problem. In the study of vegetation in polluted areas with heavy metals, plants have the ability to grow and absorption the heavy metals, viewpoint the scientific aspects, functional and economically very important.
Material and methods:
In this study 500, 1250 and 2000 meter from the center Kiasar cement of sari in Mazandaran province, soil and vegetation sampling was conducted using systematic random. Plant species such as Astragalus, Artemisia and Convolvulus with 3 replications and 3 treatments (a total of 27 samples and 27 samples of soil from the plant Rhizosphere) in the form of randomized complete block design was tested. The collected Samples transported to the laboratory for testing. The concentration of Pb, Cu, and Zn of the samples were determined by using ICP Device.
Results and discussion:
Results of statistical analysis of this study showed that heavy metals in soil had difference was greater than the species studied. So compare means of data show amount of cu and pb in soil and species had significant differences with increasing distance (p < 0.05). Copper increased with increasing distance and lead showed decreasing trend. Zn did not show any significant differences with the changes of distance in soil but it was significant differences in species and does not follow the regular process.
Conclusion:
Correlation of heavy elements of species with soil elements showed that Astragalus and Artemisia have significant Correlation with Copper and lead but Convolvulus just significant positive correlation with the Zn.
