Results reported in this study showed that BPA migrated from PC bottles even at room temperature. The release of BPA at room temperature at day 1 is due to the non-polymerized BPA in the PC bottles. Both duration of storage and temperature influenced the migration of BPA from PC bottles into the water. However, this study indicates succinctly that the impact of temperature on BPA release from PC bottles into water is significantly greater than that of storage time. The concentrations of BPA migrated were in the range of 0.036 ± 0.012 ng/mL (day one at room temperature) to 5.620 ± 0.650 ng/mL (day 10 at 60 °C) for the three brands of PC baby feeding bottles that were studied whereas the concentrations in the PC water bottles were in the range of 0.08 ± 0.01 ng/mL (day 1 at room temperature) to 4.03 ± 0.10 ng/mL (day 10 at 60 °C). The highest concentration detected (5.620 ng/mL or 5.620 µg/L is below the SML of 0.05 mg/L corresponding to TDI of 4 µg/kg bw/day set by EFSA 2018 . However, we cannot say with certainty that this level is safe for consumers because the temperature and time conditions used in this study are lower than what most people practice at home, and the presence of other factors can further trigger its release from PC bottles. Moreover, chronic accumulation of a small dose of BPA can have lifetime implications for humans. Other factors such as pH of water and residual level of alkaline detergent remaining on the surface of PC bottles Appendix 3: Absorption spectrum of 1 mg/mL BPA standard solution with maximum wavelength of absorbance at 277.2 nm
