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

BPA, from 0.6 to 2.1 ng g−1 for BPF and from 0.8 to 1.3 ng g−1 for BPS. BPB and NP were not detected and OP levels ranged from 0.5 to 3.7 ng g g−1. The results demonstrate that the developed analytical ...

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

0.6-2.1 ng g−1 for BPF and from 0.8-1.3 ng g−1 for BPS. BPB and NP were not detected and OP levels ranged from 0.5-3.7 ng g−1. The results demonstrate that the developed analytical method is very sensitive ...

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

Concern (TTC) approach. In case the estimated exposure to the unlisted substance exceeded the human exposure TTC value, a more indepth risk assessment was performed. Based on the results of both parts of ...

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

dichloromethane (DCM)-n-hexane (1:1 and 1:3). The extracts resulting from the LLE step were analysed on GC-(EI) MS by monitoring specific ions for each analyte and for the internal standard. EtOAc-n-hexane (1:1) ...

Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.

microwave, sterilisation and dishwasher, on the migration of different contaminants was evaluated by means of duration tests. These results were compared with a reference treatment (filling five times with ...

The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.

Female Humans Internationality Laboratories mothers Phenols Phthalic Acids Reproducibility of Results Abstract: COPHES / DEMOCOPHES has its origins in the European Environment and Health Action Plan of ...

In vitro model to study the endocrine disrupting activity of migration products from plastic food contact materials

replacing polycarbonate, that are used on the Belgian market, it resulted in the conclusion that polymers used for the manufacture of baby bottles are mainly polypropylene, polyethersulfone, silicone, ...

Evaluation of a screening system for obesogenic compounds: screening of endocrine disrupting compounds and evaluation of the PPAR dependency of the effect.

Our results showed the adipogenic potential of all tested parabens, several musks and phthalate compounds and bisphenol A (BPA). PPAR γ activation was associated with adipogenesis for parabens, ...

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

to 1.3 ng g−1 for BPS. BPB and NP were not detected and OP levels ranged from 0.5 to 3.7 ng g g−1. The results demonstrate that the developed analytical method is very sensitive and that levels of ...
