| Summary: | Bisphenol A (BPA) is a widely used chemical in the plastic production and it is well
known as weak estrogenic character which can give potential endocrine disruptor to
human body. In this study, trace amounts of BPA have been detected in five different
type and brands of plastic packaging sample purchased from a local supermarkets. The
concentration of BPA leaching at different temperature was measured using a simple,
sensitive and rapid UV-Vis spectrophotometric method. The detector wavelength was
set at 276 run. Linear standard curve was obtained over the range from 0.07 to 0.35 mM
with regression coefficient of 0.992 and detection limit of 0.0002 mM. Based on the
result, brand 1 of HM type has the lowest concentration of BPA leach out from sample
when it immersed in 0 °C with the detection of 1.148 x 10'7± 0.236 x 10"3 g/cm2, while
HD type sample has the highest value of concentration of BPA leaching with measurement value of 6.861 x 10‘7 ± 2.915 x 10'3 g/cm2 when it immersed in 70 °C. Although the concentration of BPA leached out from all types of plastic sample in every
different temperature were detected, though as the part of research concern, it is still
safe to use because all the values of concentration BPA detected in this study was still
under the NOAEL range (5 mg/kg bw/day). |
