Abstract :
Background and objectives: Heavy metals are considered as one of the major contaminants that can enter into
the bottled waters. Antimony (Sb) is a contaminant, which may leach from the polyethylene terephthalate (PET)
bottles into the water. The aim of this study was to investigate the content of antimony and other trace elements
in bottled waters which was kept in varied storage conditions and temperatures.
Materials and methods: Five time-temperature treatments were carried out on five different brands of commercially
available bottled waters. Heavy metal measurement was performed by Inductively Coupled Plasma-Atomic
Emission Spectroscopy (ICP-AES) method. Analysis of the collected data was processed by SPSS software.
Results: Antimony concentration was the main concern in our study. The concentrations increased in each of the
sample during storage period at all temperatures. The results for different conditions were as follow: at 40°C, in
outdoor and at room temperature the Sb concentrations were below the MCLs, i e. 6 ppb. However, at 65°C and
80°C for longer storage times Sb concentration exceeded the MCLs, and variations between the samples were
significant (p ? 0.05). Storage time and temperature effects on the content of some other trace elements such as
Al, Fe were also significant (p ? 0.05).
Conclusion: By increasing the duration of storage time and temperatures, antimony leaching from the PET bottles
into the bottled water increased. The concentration of Al demonstrated an increase in higher temperatures and
storage duration, whereas the content of Fe demonstrated no significant differences.
