Found detection limits (DL) ranged from 0.2 to 0.6 ng g(-1) and quantification limits (QL) from 0.5 to 2.0 ng g(-1) for Bisphenol A and its chlorinated derivatives, while inter- and intra-day variability was under 8.1%. The method was validated using standard addition calibration and a spike recovery assay. Recovery rates for spiked samples ranged from 97% to 105%. This method was satisfactorily applied to the determination of BPA and its chlorinated derivatives in 49 placental tissue samples collected from women who live in the province of Granada (Spain).
