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 ...

Evaluation of the potential health risks of substances migrating from polycarbonate replacement baby bottles.

non-intentionally added substances). For the listed substances, concentrations in the migration solutions were compared to their respective specific migration limits (SML) (when applicable). Migration of all ...

Study of the possible migration risks of food contact materials for children under 3 years

migration limits) showed that for some baby bottles, several not authorised compounds exceeded the generally adapted “no-detection limit” of 10 µg kg-1. Substances, such as 2,4-di-tertbutylphenol (up to 118 ...

Development and application of a non-target extraction method for the analysis of migrating compounds from plastic baby bottles by GC-MS.

concentrations were relatively low, for some compounds such as e.g. 2,4-di-tert-butylphenol; 2,2,4-trimethyl-1,3-pentanediol diisobutyrate (TXIB) or 2-butoxyethyl acetate the specified migration limit ...

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 ...
