초록
PET bottles used in water packaging are made up of small molecules ormonomers, which, together with their additives, can migrate into the water during
manufacture, filling or storage of the bottles. The purpose of this study was to
investigate the impact of various distribution and storage conditions on the release of
constituents from the PET bottle into the drinking water. Formaldehyde, acetaldehyde
and phthalates found in plastic packaging were analyzed in PET bottled drinking water
stored under different storage conditions, including indoor(18℃) and outdoor(sunlight
exposure) in 2014, indoor(25℃ with shade from the sunlight), outdoor(sunlight
exposure), outdoor with shade from the sunlight and glass bottle shaded from the
sunlight in 2015. The migration tendency increased with storage time, temperature and
sunlight exposure. However, it was not clear whether the tendency of concentration of
phthalates depended on the storage conditions. PET bottles showed a sharp increase in
the concentration of aldehydes in outdoor conditions with exposure to sunlight. In
particular, the average concentration of acetaldehyde exceeded the odor threshold under
outdoor storage conditions. The concentration of aldehyde in glass bottle was determined
to be lower than the initial concentration. Therefore, we confirmed the influence of the
material of the bottle.
