  • Descrição: Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background and Objectives: Heavy metals including antimony and cobalt as two contaminant factors leach from polyethylene terephthalate packages into water under some conditions. Therefore, their detection was concerned at different storage conditions. Materials and Methods: Five time-temperature treatments were carried out for 5 water samples. Storage conditions were defined as following: at outdoor and sunlight ambient temperature, room temperature, and at 40˚C at different intervals for 8 weeks, at 65˚C for 6 weeks and 80˚C for 7 days. Detection was performed by ICP-AES method and the data analysis was processed by SPSS software.Results: Antimony concentration increased by storage time at all temperatures and for all samples, however enhancing proportion was different in samples. At outdoor, 40˚C and room temperature, concentration increase was below the MCL by the end of storage period. But at 65˚C and 85˚C, antimony concentration exceeded MCL by study time and the difference between samples 4 and 5, for example, was significant (p≤0.05). Cobalt concentration at the beginning and during the study was also too less and lower than the detection limit.Conclusion: By increasing temperature and time, leaching of antimony into water increases. Moreover, sunlight has effect but not noticeable at the temperature of present study. In this study, blue or clear packaging had no significant effect on antimony leakage (P>0.05). /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-theme-font:minor-bidi;}
