Researchers analyzed samples of edible vegetable oils to determine if they contained potentially toxic elements. The study aimed to evaluate the health risks associated with consuming these oils in Hamadan, Iran. They found that iron, arsenic, zinc, cadmium, and lead were present in varying concentrations in these oils. While concentrations of these elements did not pose a high risk for non-carcinogenic diseases, they were above acceptable ranges for the risk of cancer. Pollution from contaminated soil and water, processing methods like bleaching and refining, and various other factors all contribute to the contamination of food sources with toxic elements. This information can be used to inform public health authorities and improve the monitoring of edible oils.
