Özet
Bisphenol-A (BPA) which is a plastic monomer acting as endocrine disruptor, can cause developmental effects and change the metabolism even at low concentrations. This study was carried out to make (i) a general assessment by performing residue analysis on the polycarbonate baby bottles, (ii) determining the factors affecting the migration of BPA to the food and (iii) determining the effect of repetitive procedures on PC baby bottles in daily use. Amount of residual BPA ranged from 0.60 ±0.05 ppm to 6.23 ±0.24 ppm and BPA migration could not be detected in any of contact conditions. Estimated daily intakes of BPA via infant formula in PC baby bottle were calculated as 1.8 µg kg-1 bw day-1 for a 3 month-old infant and 1.22 µg kg1 bw day-1 for a 6 month-old infant which was lower than but very close to the latest value of t-TDI (4 µg kg1 bw day-1) determined by EFSA. Sterilization procedures changed the amount of residual BPA significantly. Although it is concluded that the use ofbrand-new PC baby bottles does not pose a risk to health, sterilization procedures can lead to the higher amounts of migrated BPA which can be toxically important.
