What is Determination of Bisphenol in Indoor Dust Samples by Liquid Chromatography in Combination with Quadrupole Mass Spectrometry (LC-MS/MS) about?

This study has focused on the development of the method LC-MS/MS to determine 2,2-bis(4-hydroxyphenyl)propane (bisphenol A: BPA) and 4,4’-dihydroxydiphenylmethane (bisphenol F: BPF) in indoor samples by using ultrasonication extraction and solid-phase extraction for preparation. The chromatographic procedure was performed on Kinetex C18 2.1 x 150 mm, 2.6 μm column with mobile phases: 2 mM HCOONH4 in MeOH and H2O:MeOH (90:10,...). The method quantification limits (MQL) of BPA and BPF were 15.0 and 12.0 ng/g, respectively. The mean recoveries were 80.4% for BPA and 93.8% for BPF (RSD<15%). The calibration curve for both BPA and BPF was linear over a concentration range of 1.0 to 500 ng/mL (R2 ≥ 0.999). Twenty-one samples were collected from private houses, laboratories, drug stores, and plastic recycling factories in Hanoi. BPA and BPF were found in dust samples with frequencies of 85.7 and 100%, respectively. Concentrations of BPA and BPF in dust samples were in the ranges of
