Detecting of heavy metal pollution in steel factory environment health of the North of Iran

Heavy metals like cadmium, lead and mercury are inessential and toxic elements which are created by various urban, industrial and agricultural activities and cause resources pollution. In this study, the soil sample was derived from the environment within the steel factory and from the leaves and roots of poplar trees existed inside of the steel factory and also the samples of soil, leaves and roots of poplar trees were provided outside of the factory. Sampling was random and after that, the amount of heavy metals, cadmium, lead and mercury, was calculated by atomic absorption spectrometer and then studied by Kolmogorov–Smirnov test, ANOVA, T-test, Levin test and Tukey test. The results suggest that there is a significant difference between existing mercury inside and outside of factory environment. The minimum stored density is related to mercury which has been observed in the leaf and root more than the others and less than the others in aerial organs of leaves.
