Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
ultra-performance liquid chromatography-tandem mass spectrometry. Samples were extracted with acetonitrile, followed by an oxidation step using 2,3-dichloro-5,6-dicyanobenzoquinone. Further clean-up was performed by ...
Characterization of suspected illegal skin whitening cosmetics.
EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin ...
An innovative and integrated approach based on DNA walking to identify unauthorised GMOs
GMO s containing a pCAMBIA family vector, frequently present in transgenic plants. This integrated approach is performed in two successive steps on Bt rice grains. First, the potential presence of ...
Dietary exposure of the Belgian adult population to non-dioxin-like PCBs.
A dietary exposure assessment was performed, combining ndl- PCB s levels found in food with data from the national food consumption survey of 2004. Fish and fish products were the dominating food group in ...
Estimation of dietary aluminum exposure of the Belgian adult population: evaluation of contribution of food and kitchenware.
Adult Aluminum Belgium cooking environmental exposure Food Analysis Humans Abstract: An exposure assessment was performed to estimate the usual daily intake of aluminum (Al) via food and kitchenware in ...
On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
Pollution Abstract: At the time of writing, this work appears to be the first published report on the coupling of on-line solid phase extraction (SPE) with ultra performance liquid chromatography-tandem mass ...
Dietary intake of artificial sweeteners by the Belgian population.
sweeteners and specific consumption of table-top sweeteners. A conservative Tier 2 approach, for which an extensive label survey was performed, showed that mean usual intake was significantly lower than the ...
A rapid and environmental friendly determination of the dithiocarbamate metabolites ethylenethiourea and propylenethiourea in fruit and vegetables by ultra high performance liquid chromatography tandem mass spectrometry.
that, we replaced DCM with a more environmental-friendly solvent. The analytical performance was evaluated with the analysis of spiked celery samples at 50 μg kg(-1) (LOQ) and 300 μg kg(-1). The ...
Dietary intake of hexabromocyclododecane diastereoisomers (α-, β-, and γ-HBCD) in the Belgian adult population.
Hydrocarbons, Brominated Male Stereoisomerism Abstract: A study was performed to assess exposure of the Belgian population to HBCD diastereoisomers. Measurements of HBCD were performed by UPLC- MS / MS, on 45 ...
