Determination of Some Heavy Metals in Serpentinitic Soils and Rocks from Sulaymaniyah / Kurdistan Region of Iraq

The present study aimed to investigated the assessed total content of Arsenics, Ba, Pb, Rb, Sn, Sr, U and V in serpentinitic soils rocks that wide spread over Penjwin Mawat area Sulaymaniyah governorate/ Kurdistan region Iraq. This research was carried out during seasons 2018-2019 seven pedons (1, 2 3 from area, 4,5, 6, 7 area) chosen according variation chemical composition parent materials soil developed. were classified as Inceptisols, while Mollisols. results showed selected metals concentration all varied, contents heavy metal samples decreased order > Sr Ba Rb Pb As >Sn U. As, ranged between (< 0.2 11.8, 20 310, 1.3 22.7, 3.2 71.4, 4.1, 69.1 179.0, 0.1 1.9 88 277 mg kg-1) respectively. In addition, these higher compared other studied elements, with considerable on different landscapes, which reflected differences degrees weathering associative rocks. Total both areas varied values (<5 6.0, <10 10, 6 37.3, 1.2, <0.2 17.3, 5.2 137, <0.1 0.4 15 206 for
