Evaluation of the Amount of Heavy Metals in Potato and Soil of Agricultural Lands in Sefid Dasht- Chaharmahal and Bakhtiari Province in 2017

Background and Aim: Irrigation with wastewater and the use of sludge as fertilizer is one of the important issues related to health and environmental concerns. The purpose of this study was to determine the amount of heavy metals of arsenic, cadmium and lead in potato and soil of agricultural lands in Sefid Dasht in Chaharmahal and Bakhtiari Province. Materials and Methods: This study was an experimental-laboratory study. Samples were obtained from three agricultural lands with an average area of ​​one hectare. Hach digestion and Sandstone were used for digestion of soil and potato samples, respectively. Finally, the concentrations of heavy metals were measured using Varian atomic absorption spectrophotometer (AA240 model). Results: The results of this study showed that lead metal had the highest rate of accumulation in soil and potato. The calculated transfer factor was according to the Arsenic > Cadmium > Lead pattern. Conclusions: According to the results of this study, measures should be taken to prevent contamination of the soil by heavy elements. Therefore, the amount of heavy elements in the soil of Sefid Dasht should be controlled by reducing use of livestock manure and chemical fertilizers.
