Research on potentially toxic elements chromium and nickel and laboratory testing of their concentrations was carried out in the wider area of Maglaj, with the aim to detect and determine their quantities, which gave basis for discussion about origins of these pollutants in soil. Field and laboratory observations included 45 soil samples, taken by the network, which is dictated by geomorphological conditions. The most frequently sampled type of soil are fluvisol and humofluvisol. Concentration of chromium (Cr) and nickel (Ni) are obtained by the most sophisticated laboratory method (ICP-MS), with a highly sensitive detection threshold (0.1 to 10,000 ppm).
Evaluation of test results showed that concentrations of Cr (max. 954 ppm, min 154 ppm, average 457.5 pmm) and Ni (max 504.5 ppm, min 103.5 ppm; average 275.57 pmm) are significantly increased compared to the concentrations prescribed in the Regulations on determination of allowed amounts of harmful and hazardous substances in soil (Cr max = 100 ppm and Ni max = 50 ppm). Considering geological settings of surrounding area (the dominant presence of igneous ultramafic and mafic rocks) it can be concluded that high concentrations of Cr and Ni have geogenic origins, what is mean that they originate from source rocks from which they are separated through the long-term decomposition and disintegration processes.
