Abstract: A new procedure is described to determine the bisphenol A (BPA) in drinking water that was in contact with polycarbonate (PC) plastic. To evaluate the amount of BPA migrating from the plastic into the water high-performance liquid chromatography (HPLC) and gas chromatography (GC) were used. HPLC and GC enable detection of the BPA concentration as low as 0.2 μg dm⁻³ and 0.5 μg dm⁻³, respectively. Recovery of dissolved bisphenol A and other endocrine disruptors from water was also performed, locating recovery yield in the range of 82.1—93.3 % as determined by HPLC and 82.3—92.6 % by GC. The results confirmed that BPA is migrating from the PC package to the drinking water contained in it. BPA concentration in two samples of bottled drinking water of 0.49 μg dm⁻³ and 0.54 μg dm⁻³ was determined by HPLC, and 0.55 μg dm⁻³ and 0.61 μg dm⁻³ by GC analysis.
