characteristics that determined POP concentrations in breast milk of primiparous mothers in Belgium. Methods Breast milk samples were obtained from a cross-sectional sample of 206 primiparous mothers in 2014. POP ...

Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium

a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC- DAD) was also successfully validated. Next, real-life illegal antimicrobial samples, ...

Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium

resistance and drug side effects [1]. In general, the evaluation of SF antimicrobials mainly focuses on the identification and quantification of the active pharmaceutical ingredients (API s), ignoring other ...

Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
