Lobda Park is one of the busiest parks, and due to the human activities in the area which result from human waste, sewage and pollution from cars , And because of these pollutants, our beaches are exposed to heavy metal pollution, which in turn affects the living organism. The increase in concentrations of heavy metals exceeds the limit allowed to serious diseases that are exposed to humans when they touch the soil or inhalation of the air. Therefore, we have to measure the concentrations of these elements in the sandy soil of the beach and find solutions to pollution If any. This study To determine the concentration of heavy metals in sandy soils. Cobalt, zinc and cadmium concentrations in the soil were estimated from three areas: the first of the beach, the second, 82 meters, the third 164 meters from the beach, and three different depths for each area. The results showed a slight increase in the concentration of zinc in the soil in the three studied sites where the concentration rate was 4. (117 mg / kg) in the surface layer, On the other hand, the cobalt concentrations in the surface layer of the soil are lower than their concentrations in the other layers, indicating the movement of this element through the soil layers. The cadmium component is found in the soil very little(2 mg / kg) in the surface layer, general, concentrations of cadmium and zinc are within the limits allowed by the World Health Organization (WHO), while cobalt contamination is present in the three studied area.
