Arsenic is one of the most toxic elements, naturally present in the environment. It enters the food chain through soil, water, and air, posing a severe health risk, especially when found in high concentrations in food. Rice is particularly at risk, with arsenic levels potentially more than ten times higher than other cereals. Long-term exposure to inorganic arsenic is linked to skin diseases, cancer, and developmental issues in children. Arsenic is also present in seafood and fish.
