Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
limits of detection and quantification are in the range of 0.1–0.3 ng g−1 and 0.2–0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...

Assessment of estrogenic compounds in paperboard for dry food packaging with the ERE-CALUX bioassay
specific analysis. Estrogenic activities ranged from 682 ± 66 pg E2 eq./dm2 to 3250 ± 400 pg E2 eq./dm2 for “worst case” extraction and from 347 ± 30 pg E2 eq./dm2 to 1350 ± 70 pg E2 eq./dm2 for migration ...
Evaluation of a screening system for obesogenic compounds: screening of endocrine disrupting compounds and evaluation of the PPAR dependency of the effect.
step, a range of EDC s, used in personal and household care products (parabens, musks, phthalates and alkylphenol compounds), were tested to further evaluate the obesogenicity screening assay for its ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
levels (0.5–5 and 25 ng g−1). The parameters accuracy and precision fulfill the criteria. Calibration curves are linear between 0.5 and 50 ng −1. The limits of detection and quantification are in the range ...
