PCDD/Fs and dioxin-like PCBs in home-produced eggs from Belgium: levels, contamination sources and health risks.
Polychlorinated Biphenyls Risk Assessment Seasons Soil Abstract: This paper discusses the dioxin TEQ levels as determined by the chemically activated luciferase gene expression assay (CALUX) and by HRGC- HRMS in ...
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 ...
Validation of the CALUX bioassay for PCDD/F analyses in human blood plasma and comparison with GC-HRMS.
samples were obtained in 2000. In total, 496 samples were collected for GC- HRMS and CALUX analyses to verify statistical assessment conclusions. This study was seen as an opportunity to validate the CALUX ...
Interpretation of CALUX results in view of the EU maximal TEQ level in milk.
associated with them. This paper explores the use of CALUX data as quantitative screening results. The validation of the method for the polychlorinated dibenzo-p-dioxins (PCDD)/F TEQ determination in milk ...
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 ...
Analysis of Ah receptor pathway activation by brominated flame retardants
gene based CALUX assay. The results demonstrate the ability of BFR s to activate the AhR signal transduction pathway at moderate to high concentrations as assessed using both assays. AhR-dependent ...
The international validation of bio- and chemical-analytical screening methods for dioxins and dioxin-like PCBs: the DIFFERENCE project rounds 1 and 2
project DIFFERENCE is focussed on the development, optimisation and validation of screening methods for dioxin analysis, including bio-analytical and chemical techniques (CALUX, GC- LRMS / MS, GC Service: ...
