Assessment of hazards and risks associated with dietary exposure to mineral oil for the Belgian population

Source: Food and Chemical Toxicology, Volume 149 (2021) Keywords: CALUX® bioassay endocrine activity genotoxicity Mineral oil aromatic hydrocarbons Mineral oil saturated hydrocarbons Modified Ames test ...

Assessing the receptor-mediated activity of PAHs using AhR-, ERα- and PPARγ- CALUX bioassays

Chemical Toxicology, Volume 145 (2020) Keywords: CALUX bioassay Endocrine disrupting compounds (EDCs) Environmental chemistry In vitro toxicology Polycyclic aromatic hydrocarbons (PAHs) Abstract: Polycyclic ...

Assessing the endocrine activity of PAHs using the DRE-, ERE- and PPARγ CALUX bioassays

was to determine the endocrine activity of 9 PAH s using three different CALUX bioassays: DRE- CALUX, ERE- CALUX and PPAR γ CALUX. Materials and methods Three CALUX (chemically activated luciferase gene ...

Assessment of estrogenic compounds in paperboard for dry food packaging with the ERE-CALUX bioassay

exposure and mixture effects of these EDC s, they could cause health effects even at very low doses. Many EDC s are still unknown and many more are still unregulated. The ERE- CALUX bioassay was used as ...

Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium

routinely monitored in  targeted chemo-analytical methods and can detect them at low amounts (pg/L EEQ, Estrogen EQ uivalence).  The bioassay used in this study is the CALUX (Chemically activated luciferase ...

The CALUX bioassay: Current status of its application to screening food and feed

polychlorinated-biphenyls recommendation Recommendations response Sample Samples SCREENING Screening method standards status Strategies Strategy study tolerance use Abstract: The CALUX bioassay is at present the best ...

TEQ-value determinations of animal feed; emphasis on the CALUX bioassay validation

method is laborious and very expensive, therefore cheap and rapid bioassays have been developed. The chemical-activated luciferase bioassay (CALUX) bioassay uses a recombinant cell line, which responds to ...

Interpretation of CALUX results in view of the EU maximal TEQ level in milk.

that require confirmation of their dioxin TEQ level. When bioassays are used as screening tools, the interpretation of the obtained results should consider the higher variability and uncertainty ...

Validation of the CALUX bioassay for PCDD/F analyses in human blood plasma and comparison with GC-HRMS.

of the CALUX bioassay for the analyses of the dioxin fractions of blood plasma. The sample preparation is based on a liquid-liquid extraction, followed by an acid silica in series with an activated ...

Importance of REP values when comparing the CALUX bioassay results with chemoanalyses results Example with spiked vegetable oils.

Talanta, Volume 63, Issue 5, p.1255-9 (2004) Abstract: Differences between chemical activated luciferase gene expression (CALUX) bioassay and chemoanalyses results are observed. This paper shows that ...
