Dietary exposure of children to Bisphenol A through feeding bottles under real use conditions was investigated. Polycarbonate is widely used in the manufacture of food containers and Bisphenol A can leach out into liquid food material. Three sets of six feeding bottles each from different brands were used in the study. In all cases the bottle treatment and the leaching conditions were selected so that each set of six bottles was subjected to real use conditions and for each liquid (milk, apple juice and water) a new set of six bottles was used. Bisphenol A was estimated by high performance liquid chromatograph with fluorescence detector. 0–3.82 ppb Bisphenol A was found when boiled water at room temperature was filled in the feeding bottles and then infant milk powder was added and kept for 30 min. When boiling water at 95 °C was added to the baby bottles and then milk powder was added and kept for 30 min Bisphenol A was found in the range of 0–7.06 ppb. In cases the baby bottles were filled with boiled water and kept for 30 min at room temperature 0–5.90 ppb Bisphenol A was detected. No leaching was detected when baby bottles were filled with apple juice. The highest concentration of Bisphenol A up to 46.05 ppb, was detected in the water used for sterilisation of baby bottles.
