In accordance with the role and importance of which in the world and in our country is attached to soil as a bio production factor, the need to examine and protect soil from contamination is imposed. Heavy metals are very common contaminants of soils. Highly toxic and carcinogenic PAHs are natural components of raw petro chemical compounds. Due to their negative influence on plants and animal world as well as on human population, it is necessary to evaluate and determine heavy metals and PAHs content in soils, especially in ones intended for agricultural production.
In this work, we have examined agricultural and urban soils in the Canton Sarajevo, for content of heavy metals and polycyclic aromatic hydrocarbons. Analyzed samples were in scattered state, taken from a depth of 0-30 cm. The total number of determined soil samples was one hundred and twenty (120), in the period of 2009-2015.
According to determined general chemical characteristics, soils are from slightly acetous to slightly alkaline. According to mechanical texture composition, examined soils have showed the following texture marks by Ehwald: clay and sandy loam.
Using flame/electrothermal atomic absorption spectrometry and gas chromatography with FID detection we have established the content of seven heavy metals and polycyclic aromatic hydrocarbons. In determining the content of heavy metals following methods were used: BAS ISO 11466:2000 and BAS ISO 11047:2000, and for PAHs the method was BAS ISO 18287:2008. Results were compared with the limit values from "Regulation on determining the allowable amounts of harmful and dangerous substances in soils and methods of their examination" specified in Official Gazette of the Federation of B&H, No. 72/09.
