Abstract:
In this study, the total concentration and changeable (mutual) concentration of Cadmium were determined in the agricultural soils in Banias region( Tartous- Syria). Soil samples from five sites from the north-east of the thermal station and the following dimensions: first 200 m, second 2000 m, third 4000 m, fourth 6000 m, fifth 8000 m from the thermal station. samples we taken at each site from two layers: sample from topsoil (0-20)cm, and sample from subsoil (20-40)cm. The relationship studied between this concentration and some soil properties. The study showed that the total concentration of cadmium in the surface layer of soil ranged between 1.82 – 1.35 mg/kg In the subsurface soils 1.85 – 1.29 mg/kg. The values of changeable concentrations cadmium in topsoil ranged between 0.87 – 0.66mg/kg and in subsoil 0.83 – 0.63 mg/kg. The concentration of cadmium in the topsoil is higher than the subsoil at all sites. All concentrations are within the natural limits and did not exceed the critical limit of 2 mg/kg, There was a positive correlation between total amount of cadmium with organic matter, clay content of soils, CEC and distance of station.
