Due to the accumulation of heavy metals in soil and their risk to human health, their recognition, origin and distribution have attracted considerable attention in recent years. Pollution of soil significantly reduces the environmental quality and the human health. Chemical approaches for evaluating soil pollution are often difficult, expensive and destructive, therefore recently methods dealing with magnetometry which are quick, inexpensive and non-destructive have been proposed as a proxy for assessing the heavy metal pollution of soil. There is little information about the status and distribution of heavy metals in soils of Kurdistan province, therefore, this study was conducted to assess the bio-environmental total concentrations of some heavy metals and the factors influencing them in soils developed on some igneous rocks (gabbro-basalt, diorite-gabbro, gabbro-diorite, monzodiorite, spilite-basalt, granite and porphyritic-granite) and relationship with magnetic properties of soil in South-East Kurdistan province. A total of 76 soil samples from a depth of 0-10 cm were taken from an area of about 260 km 2 . Location of the sampling points was determined using GPS device and parent material of samples was determined using the geology map. After collecting soil and rock samples, the magnetic susceptibility at two frequencies 0.46 kHz (? lf ) and 4.6 kHz (? hf ) were measured and the frequency dependence of magnetic susceptibility (? fd ) also was calculated from the related equation. Concentrations of total iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), lead (Pb), nickel (Ni), cobalt (Co) and chromium (Cr) in soil and rock samples after extraction was measured using atomic absorption spectrometry. Because of low concentration and insufficient of detection limit of AAS device , Pb wasn’t detected. Selected soil chemical and physical properties including electrical conductivity, pH, calcium carbonate equivalent, sand, silt, clay and soil organic matter in samples were determined to understand the relationships between magnetic susceptibility and soil properties . The results showed that in the studied area, Fe, Mn, Ni, Cu and Cr indicated positive significant correlations with ?fd indicating the existence of super-paramagnetic particles in the region. Therefore, it seems that frequency dependent of magnetic susceptibility could be applied as an indicator of contamination of heavy metals in the soils developed on igneous rocks. Magnetic susceptibility value at all soils decreased as compared to parent rocks except soils located on the monzodiorite and gabbro-diorite. This was attributed to change of ferromagnetic minerals to diamagnetic minerals during weathering processes. Among the selected heavy metals Cu showed the highest enrichment factor. Ni and Cr had the moderate and the remaining metals had low enrichment factor. Co and Ni indicated positive significant correlations with silt and negative relation with sand content. Similar trend was observed for dependent frequency magnetic susceptibility. Negative significant correlations were obtained between magnetic susceptibility and Fe, Mn, Ni and Cr contents in soils. Positive significant correlations were observed between Cu concentration in soils and Cu in rock samples, indicating parent material effects on its concentration in soils. Positive correlations were observed among selected metals concentrations in rock samples. Moreover, positive and significant correlations were obtained for metals concentration in soils, indicating similar sources for them. Distribution of metals concentration in the study area showed that Ni had the highest ( 96.8% of samples) pollution concern, as their values exceeded from the guidelines established by the Netherlands, wherea for Co, Cu, Cr, and Zn, exceeded in 95.4, 23.1, 12.5 and 4.7 percent of the studied sites, respectively. In general, the highest concentrations of metals were obtained for Co, Ni, Fe, Mn, and Cu in soils developed on gabbro-basalt and for Zn and Cr in soils developed on granite and split-basalt. Overall results revealed that magnetic susceptibility at low frequency could not provide valuable information according to heavy metals concentration in soils developed on igneous rocks far from away the anthropogenic activities.
