Abstract:
Toxic elements (arsenic,cadmium,lead,andmercury) are public health concerns and listed as priority pollutants for their severe toxic effects, especially in children, whose biological systems are developing. The aim of this study was to determine the concentrations of toxic elements (As,Cd,Pb,andHg) in plastic utensils using x-ray fluorescence and pecific migration tests. The utensils were cleaned with na Extran detergente and analyzed using a portable XRF analyzer. Specific migration tests were conducted using water and 3 % acetic acid as food simulants under two test conditions: rapid (2hat40◦C) and long (10daysat25◦C), followed by inductively coupled plasma masss pectrometry analysis. A total of 54 utensils were analyzed, revealing mean concentrations of Cd, Pb, As, and Hg of 20.9, 31.3, 10.4, and 14.45 mgkg−1, respectively. Alarmingly, Cd, Hg, and Pb exceeded specific migration limits on the rapid tests by factors of 18.6,34.5, and 5027, respectively, whereas Hg and Pb exceeded limits on the long tests by factors of 2 and 22, respectively. Statistical analyses confirmed significant associations between utensil type/colorand element concentrations. The high levels of toxic elements found unders core the urgente need for coordinated action to protect health and ensure food and environmental safety.
