RESEARCH OF THE RELATIONSHIP BETWEEN THE CONTENT OF HEAVY METALS IN SEDIMENT DUST AND AGRICULTURAL SOIL IN THE AREA SURROUNDING THE STEELWORKS ZENICA

This paper contains analysis of the results after monitoring the content of heavy metals (Pb, Cd, Fe, Zn, Ni, Cr and Mn) in sediment dust and agricultural soil in nine locations surrounding steelworks Zenica from March to August in 2016. The aim of the paper is to analyze and assess connection of the content of heavy metals in sediment dust and in soil surrounding steelworks Zenica in order to rate soil contamination caused by heavy metals that have been emitted from metallurgic plants, and in order to evaluate the industrial emissions effect on the environment and human health. It has been established that the biggest sample number of sediment dust is being loaded by Nickel and Cadmium, and soil samples by Nickel and Manganese. By applying Pearson coefficient, it has been concluded that there is a strong relation between Lead and Zinc, and a medium strong relation between Iron in sediment dust and soil, while other analyzed metals do not show significant correlation in terms of statistics. This shows that Lead, Zinc and Iron in the soil are probably of techno-genic origin, and the other metals are of primarily geological origin. The correlation analysis of metal substance in soil and sediment dust in measuring areas has shown that there is a statistically significant correlation between Zinc in sediment dust and soil in the following areas: Gradi?će, Arnauti and Novo Selo, and correlation of Chromium in sediment dust and soil is present in ?erići.
