Due to the development of civilization, the use of single-use food containers has increased, which causes a risk resulting from the release of toxic and harmful heavy metals during daily use. This study aims to estimate the concentrations of heavy metals from the leachate at different temperatures (40, 70 and 100 ℃): zinc (Zn), manganese (Mn), cadmium (Cd), chromium (Cr), nickel (Ni), cobalt (Co). Lead (Pb), iron (Fe), and copper (Cu), and an assessment of the health risks resulting from three polymeric materials to children, adolescents, and youth (Aliphatic polymer, polymeric aromatics, and polystyrene). Concentrations of heavy metals were observed at 40 ℃, and they increased as it rose to 100 ℃. The concentrations were arranged, the highest concentrations were for nickel and Lead, and the lowest concentrations were for chromium. It was found that the hazard quotient (HQ) for all values is less than 1, which means there are non-cancer risks from metals that may not occur, the results of the excess lifetime cancer risk (ELCR) that Nickel and lead, for aliphatic polymer leachate and Nickel for polystyrene leachate, for young people at 100 ℃ considered the most exposure to cancer risk than aromatic polymer, so that aromatic polymer containers are safer than others containers, especially at high temperatures for adolescents and young people. This requires increasing awareness about the use of disposable food containers, in addition to conducting more research about the impact of Poly fluorochemicals, bisphenol A (BPA), and others on human health.
