Results reported here clearly show that migration occurs daily as can be seen in tables 1 and 2 above but the difference between the levels of BPA migrated each day is not statistically high enough for us to conclude that storage duration has a very high impact on the BPA migration. This may be because the time scale chosen for this experiment (1-10 days) is not sufficient enough compared to some works that extended up to six (6) months. After all, prolonged usage may weaken the polymer surface. This would further increase the surface area of the polymer and increase the contact ratio between the food/beverages including water and the polymer which would subsequently enhance the rate of BPA migration into food/beverages in the future. This would increase the migration of BPA from PC plastics at a rate > 0.049 ng/mL per feeding due to the enhancement of average interspacing (d-spacing) of PC bottles, by repeated use leading to an increase in the diffusion of BPA unto the surface of the PC bottles for contact with food and beverage .
