Abstract

The purpose of this study was to estimate the degree of contamination of soils surrounding the Safraqiah’s Dam in Qurdaha city in Lattakia by lead (Pb), and Nickel (Ni), and study their mobility by estimating the total amount by using the method of digestion with aqua regia, and water extracted form (dissolved form) in the area’s soils. Soil samples were collected from eight sites on surrounding sides of the Safrqiah’s Dam and on two depths (0-30 cm) \ (30-60 cm), for estimating some physical and chemical properties of the soil, and the total and the water-soluble forms. The mean achieved results that the total amount of Pb element was within normal limits is the agricultural lands, because it did not exceed (100 mg/kg), but it was outside the permissible limits in agricultural lands of Ni (50 mg/kg). While the amount of dissolved forms were high for the both elements, it was (2.57 mg\kg) for lead and (2.65 mg\kg) for nickel. On the other hand the percentage for water soluble forms of the total amount was for Pb and Ni (3.25%), (5.1%) respectively. Thus, there is a leaching risk in to the ground water and a possibility of absorption by the plants, especially in clay to sandy soils

Key words: Soil pollution, Heavy metals, Lead, Nickel.
