Abstract: (29 Views)
Background: The Veys region in Khuzestan Province is one of the important agricultural regions in the northeast of Ahvaz, where various vegetables, herbs, and grains are grown in its fields. The present study was conducted in the autumn of 2024 with the aim of evaluating the status of potentially toxic elements in the soil of agricultural fields in the city of Veys.
Materials and Methods: In this study, 80 samples were taken from the surface soils of agricultural fields in the Veys region in the northeast of Ahvaz. A Varian 710-ES ICP-AES atomic absorption-plasma device manufactured by Agilent, USA, was used to measure metals.
Results: The average Cf, Cdeg, mCd and PLI of toxic elements in the surface soils of agricultural fields in the city of Veys, northeast of the Ahvaz metropolis were 1.46, 14.41, 2.40 and 1.23. Also, the NIPI and the Er index of toxic elements were calculated to be 5.19 and 260.05. The highest carcinogenic risk index of toxic elements in the surface soils was obtained for chromium metal for children (1.52×10-1) and adults (4.79×10-2). The lowest carcinogenic risk index for adults was for cadmium metal (9.20×10-3) and for children it was for arsenic metal (9×10-2).
Conclusion: The values of Cf, Igeo and Er showed that the soils of the studied areas are contaminated with potentially toxic elements. Evaluation of the non-carcinogenic risk index and carcinogenic risk index of potentially toxic elements of surface soils of agricultural fields in the northeastern city of Weiss showed that the elements Cd, Pb, As, Cu, Zn and Cr do not pose a problem for human health.
