en Food safety and hygiene Original articles <div style="text-align: justify;"><strong><em>Introduction:</em></strong> In recent years, the contamination of food with heavy metals has received much attention. Plants can absorb metal pollutants through contaminated water, soil, and air.<br> <strong><em>Materials and Methods:</em></strong> In the current study, accumulation of minerals in three types of soybeans was investigated by wet and dry digestion methods using ICP-OES technique. Thereafter, the metals&#39; health risk was assessed by estimated daily intake, toxic hazard quotient (THQ), and hazard index (HI) values.<br> <strong><em>Results:</em></strong> According to the results, the concentrations of Cr, Se, Ca, Fe, Mo, Mn, and Mg in soybean seeds were 0.034-170.88 mg/kg, 0.21-243.79 mg//kg, 2.50-33.37 mg/kg, 0.05-0.86 mg/kg, 0.071-203.57 mg/kg, 0-0.47 mg/kg, and 2.69-19.31 mg/kg, respectively. The ashing method had a better performance in determining Ca, Fe, Mo, Mn, and Mg concentrations than the wet digestion method. The THQ rates were below 1 for the three varieties of each mineral element, but the HI values of variety 2 and variety 3 were higher than 1 in both methods.<br> <strong><em>Conclusion:</em></strong> Furthermore, continuous monitoring of the soybeans&#39; mineral and heavy metal contents seems necessary.</div> Soybean, Digestion Method, ICP-OES, Risk Assessment. 1010 1015 http://jehsd.ssu.ac.ir/browse.php?a_code=A-10-121-2&slc_lang=en&sid=1 Narjes Khalili narjes.1357@yahoo.com 0000-0001-8075-7529 Yes Community Medicine Specialist, Preventive Medicine and Public Health Research Center, Department of Community Medicine, School of Medicine, Iran University of Medical Sciences.
