An Investigation of Contamination of Heavy Metals of Zinc and Cadmium in Soil and Plants of Squares of Meshginshahr Town

Abstract

According to limitation of resources of earth, provision of health food security of growing population of the world in a way to have the least destruction in environment is considered as of the most importance. The present study aims to determine amount of concentration of heavy metals of zinc and cadmium in main squares of Meshginshahr City. In this research, to investigate position of concentration of heavy metals of zinc and cadmium in main squares of Meshginshahr Town, first position of sampling from soil and plants in main squares of Meshginshahr City was determined and eight squares were selected. Data obtained from this research was statistically analyzed by SPSS software. Pearson Correlation Test was used to determine correlation of samples and one-sample t-test to consider meaningfulness of samples, Kolmogrorov-Smirnov Test to determine normality of data and variance analysis test to investigate average of concentration of data were used. Results indicated that amounts of concentrations of heavy metals of zinc and cadmium in measured squares were less and standard limit of FAO and so it was meaningful. Also, results of Pearson Correlation Analysis did not indicate a meaningful relationship between amounts of concentrations of heavy metals of zinc and cadmium in soil and plants. Also, results of analysis of data variance indicated that there is not a meaningful difference between metals in soil and plant.
