Distribution and Enrichments of Abundant and Trace Elements in Al-Khassa Sub Basin Soil, Kirkuk, Northeastern of Iraq

This study focused on the soil of Al-Khassa Sub Basin, thirty-four samples were collected from different areas land use and differences in human activity. Physicochemical properties examined Hydrogen Potential (pH), Organic Matter (O.M), Loss Of Ignition (L.O.I), Total Carbon (TOC), Cation Exchange Capacity (CEC) Hydrocarbon (THC). (pH) showed that is alkaline above seven with a mean 7.98. (O.M) area 1.28 % high value found Agricultural areas.Cation 42.64 (cmol/kg) proportional to granular size silty clay. Both (TOC) (THC) acceptable concentration values compared soils arid region. In present abundant elements (Calcium (Ca), Silicon (Si), Aluminum (Al), Magnesium (Mg), Sulfur (S), Potassium (K), Chloride (Cl), Titanium (Ti) Phosphorous (P) ) Trace element(Chromium (Cr), Manganese (Mn), Nickel (Ni), Zinc (Zn), Vanadium(V), Copper(Cu), Lead(Pb), Arsenic (As), Cobalt (Co), Mercury (Hg) Molybdenum (Mo)) have been analyzed this limits distribution world local Lesser Zab. Elements are higher than standard Ca, Cl, Cu, As,Hg, Mo, Zn because excessive fertilizers pesticides poor irrigation practice other anthropogenic sources. High (Ni, Co) as result weathering parent rocks, it occurs naturally soils. Other partially (K, Cr, P, S, Mg( only dense agricultural areas. lower Standard (Ti, Al, Si, Mn, V, Pb) represent unpolluted at some locations sub-basin they increase urban industrial not available main activity sub basin rural cultivated land. The results enrichment factor (EF) contamination (CF) calculated for assessment. Enrichment EF 2 depletion minimal enrichment, indicating no or pollution, but there real beginning magnesium element 2-5 moderate element. pollution due presence farms sulfate by villagers sedan. Contamination Factor region low Except Mam Rash (S22), Belgrad (S10) was very degree Cf > 6, Sedan (S25), Gurgay Shammar (S11), Obarick (S32) considerable 3 < 6 three villages fertilizer. Phosphor Heon (S7), Ali Makaeel (S20) phosphate beside occurrence poultry farms.
