Abstract:
This study aimed to determine the concentration of heavy metals: lead (Pb), cadmium (Cd), copper (Cu), nickel (Ni), and zinc (Zn) in surface soils (0-20 cm) for nine sites )S1 to S9) in Banyas city. During the year 2021. The results showed that the ranking of elemental concentrations (general average) in ppm were as follows: [Mn (577.06) > Zn (69.32) > Pb (30.69) > Ni (28.20) > Cu (25.49) > Cd ( 0.55)] and these values were above the normal value for lead (27 ppm), cadmium (0.4 ppm) and manganese (488 ppm), while copper was below the normal value (38.9 ppm), and were close to the normal value for zinc (70 ppm)and nickel (29 ppm). The results showed that the highest value of lead was in the (S9) site, cadmium in the (S9, S1 and S8) sites, and the highest values of zinc were recorded in the (S5 and S7) sites. The highest values for nickel were recorded at the sites (S8 and S5) for manganese, and the highest values were recorded at the sites (S7, S3 and S4).The results also showed a positive significant correlation between the values of nickel and cadmium and between lead and cadmium, as well as a significant negative correlation between nickel and manganese.
