Determination of heavy metals in Iranian food packaging plastic
Dissemination of End-users to heavy metal is a salient issue where many researchers have been attentive on this subject for decades. These Metals can unfurl the Human Body via food contact consumption. So this research aims to investigate the content of heavy metals (lead, cadmium, chromium, iron, cobalt, copper, barium nickel, zinc, and arsenic has been determined in thirty-two different Iranian plastic food packaging containers by using Inductive-coupled plasma optical emission spectroscopy (ICP-OES) using Microwave digestion system. In Adding to that, The Investigated packed materials like which Includes Dairy Products, mayonnaises, and kinds of ketchup. The Results ended up claiming heavy metals ranges are Pb(0.018-1258 mg/kg), Cu(0.41-31.13 mg/kg), Ni(0.06-0.866 mg/kg), Zn(7.27-88.69 mg/kg), Fe(4.7-901.6 mg/kg), Cr(0.87- 273.13 mg/kg), Cd(0.003-0243 mg/kg), Co (LDL - 0.358 mg/kg) and As(0.017-0.387 mg/kg). Lead (Pb) was detected at concentrations of 0.018-1258 mg/kg in eight of 32 packages. The highest concentrations were detected for Lead in the yellow and green-colored samples.
