Abstract, British Journal of Pharmacology and Toxicology, 2010
A research study was conducted to show some traditional utensils as potentials sources of poisoning by heavy metals. Milled rice was cooked in a traditional aluminum pot to assess the level of contamination of food by the utensil when cooking. Results showed that aluminum content of cooked rice increased from 1.6 to 18.1 mg/g, more than 11 times (ATT = 11.31). It was also demonstrated that protective layer of inert material present in modern utensils was a good way to protect food from contamination while cooking. Analysis of the mineral composition of an other traditional utensil made of clay showed a high content of aluminum (87.5 mg/g) showing that it is also a potential source of food contamination by aluminum.
