Abstract
UDK 631.41:631.482(1-751.2 Una)(497.6)
 The paper presented results of a comparison of alluvial soils of different land use at two sites within the National Park "Una". The sites were related to a natural meadow (BUK) and artificial meadow (KLISA). The main objective of the research, in addition to the physical and chemical parameters of soil quality, was to determine the distribution of the total content of cadmium (Cd), nickel (Ni) and arsenic (As). The total content of these elements were observed in composite samples at two depths of 0-10 cm and 0-20 cm and horizons profile. Their total content was measured by atomic AAS. The results were analyzed using Kruskal – Wallis test (p≤0.05) using coefficient χ2. The results showed a single legality of the distribution of Cd, Ni and As in samples of soil profile, while the average soil samples showed unique legality of the distribution of observed elements.
Highlights
In recent decades the area of the National park „Una“ has stirred the interest of many scientists and researchers (Alibabić and Bašić, 2005; Bašić and Čustović, 2005; Muhamedagić, 2010, etc)
The study has placed a special emphasis on the distribution of the total content of cadmium (Cd), nickel (Ni) and arsenic (As) in the average samples (0-10 and 0-20 cm) and by depth of the soil profile
The pH levels established at the sites of BUK and KLISA ranged from slightly to very alkaline with an upward trend with the profile depth
Summary
In recent decades the area of the National park „Una“ has stirred the interest of many scientists and researchers (Alibabić and Bašić, 2005; Bašić and Čustović, 2005; Muhamedagić, 2010, etc). The issues of distribution of toxic elements in the soil have been dealt with, both in our country and the world, by many researchers coming from different functional areas: industrial (Shakeri et al, 2009; Dheeba and Sampathkumar, 2012, etc.), urban (Romić and Romić, 2003, etc.), landfills (Dellantonio et al, 2007, etc.) and protected areas (Maksimović et al, 2013; Muhamedagić, 2015, etc.). This paper presents the results of a comparison of alluvial soils of different use with in the National Park „Una“. The first site of BUK (altitude: 284 m) and the second site of KLISA (altitude: 301 m) (Figure 1-2)
