The paper presents the results of a comparison of brown rendzina and colluvial sinkhole at approximately the same altitudes and the same land use. The sites were located in the Kalati area within the National Park „Una“. More precisely, the places referred to the top of the sinkhole (brown rendzina top) and the bottom of the sinkhole (colluvial soil bottom). 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 werw observed in composite samples at two depths of 0 – 10 and 0 – 20 cm and horizons profile. Their total content was measured by atomic adsorption spectrometry – AAS. The results were statistically analyzed using Kruskal Walisovog test at the significance level of p ≤ 0.05 using correlation coefficient χ. 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.

Man in ecology as a multidisciplinary scientific field is one of the key ecological factors of the environment. Viewed historically, in its existence it is constantly changing and influencing the natural environment and adapting it to its needs. Namely, considering in general, we are witnesses that today's situation on Earth is greatly disturbed from the point of view of human influence and ecology. We are also witnessing multiple changes and consequences of environmental damage that occur in the context of global environmental problems or even environmental crises. Some of the major environmental problems faced by today's man are: climate change, the emergence of the "greenhouse effect", damage to the ozone layer and the emergence of so-called. ozone "holes", pollution of environmental media such as soil, water and air, biodiversity loss, waste, uncontrolled exploitation of natural resources, radioactivity, desertification and more. Global ecological problems, i.e. their emergence, are associated with the emergence of an irrational relationship and the creation of a rift between man himself and nature. In addition to the above, their occurrence is also associated with the effects of various sources of environmental pollution. Precisely because of all the above, the paper analyzes and deals with the role of man as an ecological factor and some of the listed global environmental problems of today, taking into account the short Islamic aspect.

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.
