Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
method is very sensitive and that levels of several compounds with known /suspected endocrine disrupting properties could be detected or quantified in human placenta samples. The results therefore suggest ...
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 ...
Study of the possible migration risks of food contact materials for children under 3 years
Monitoring and quantification of these compounds was done using GC- and LC-QqQ- MS methods, for which several validation parameters were determined (sensitivity, selectivity, linearity, accuracy, precision, ...
Evaluation of a screening system for obesogenic compounds: screening of endocrine disrupting compounds and evaluation of the PPAR dependency of the effect.
discriminative power and sensitivity. Additionally, the peroxisome proliferator activated receptor γ (PPAR γ) dependency of the positive compounds was evaluated using PPAR γ activation and antagonist experiments. ...
