The results obtained in this work agree with results previously reported as detectable levels of bisphenol A (BPA) were observed right from day 1 at room temperature for all the samples of water in the PC bottles that were studied suggesting the presence of residual BPA in the studied PC bottles. BPA levels migrated from the three different brands of PC baby feeding bottles ranging from 0.036 ± 0.012 ng/mL (day 1 at room temperature) to 5.620 ± 0.650 ng/mL (day 10 at 60 °C). The levels of BPA detected in PC drinking water bottles were in the range of 0.08 0.01 ng/mL (day 1 at room temperature) to 4.03 ± 0. Several authors reported detectable levels of BPA right from day 1 even at a short duration of time, about 30 min. However, this depends on the way samples were prepared before the analysis and the assigned temperature conditions corresponding to the ways that consumers normally treat their PC containers at home before beverages are being stored in them. Cao and Corriveau 2008 reported migrated concentrations of bisphenol A at the range of 32 -55 ng/mL (day 1) to 228 -516 ng/mL (day 6) at 70 °C . In another work conducted by a group of researchers, a concentration range between 5.5-7 ng/mL was reported at 80 °C after 1 h . Biedermann-Brem and Grob in 2008 also reported BPA concentration range of 0.5 -18 ng/mL . In all of these studies, there is a positive correlation between the release of BPA from PC plastics and temperature & time. In another study by , the concentrations of BPA migrated from PC baby bottles in the range of 2.4 -14.3 ng/mL . According to a study by , the concentrations of BPA migrated from brand-new PC baby bottles were reported to be 0.03 ng/mL to 0.13 ng/mL at 40 °C and 95 °C respectively whereas the concentrations range of 0.18 ng/mL to 18.47 ng/mL were reported for the bottles that were used for 6 months at 40 °C and 95 °C respectively. It was observed that the levels of BPA migrated rapidly increased when the water temperatures were above 80 °C for 6-months used PC baby bottles. The authors concluded that temperature is the significant factor that favors BPA migration from PC bottles to water . Results reported in this work compared favorably with the work by Brede et al that reported the concentration of BPA from PC baby bottles at the range of 0.11 -0.43 ng/mL (1 time of testing corresponding to new PC bottles at 70 °C) and a work by Le et al (2008) that reported concentrations of BPA migrated from PC water bottles at the range of 0.08 ± 0.06 ng/mL (day 1 at room temperature) to 1.33 ± 0.09 ng/mL (day 7 at room temperature) for 3 brands of PC bottles studied . They stated succinctly that exposure to elevated temperatures above those typically used for washing by consumers but not outside normal household practice (e.g., boiling to sterilize infant feeding bottles) or outdoor applications (addition of very hot or boiling water or beverages to drinking bottles) greatly elevated the rate of migration .
