Human urine contamination with environmental pollutants: simultaneous determination using UPLC-MS/MS
the range of 0.88-84.46 ng/mL, 0.52-29.2 ng/mL, and 0.51-28.17 ng/mL of PP, MP, and EP, respectively. In addition, the concentrations of the paraben derivatives in women were higher than those of men. ...
A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD
quality control of nicotine related impurities, for which the European Pharmacopoeia limits are currently applied, the sensitivity of the UHPLC- DAD method was found to be within the acceptable range ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
limits of detection and quantification are in the range of 0.1-0.3 ng g−1 and 0.2-0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...
Prioritizing substances of genotoxic concern for in-depth safety evaluation using non-animal approaches: The example of food contact materials.
substances could all be assigned to one of the four priority classes (ranging from low to very high concern). Importantly, 19 substances were considered of very high concern due to in vivo genotoxicity. Five ...
Assessment of estrogenic compounds in paperboard for dry food packaging with the ERE-CALUX bioassay
specific analysis. Estrogenic activities ranged from 682 ± 66 pg E2 eq./dm2 to 3250 ± 400 pg E2 eq./dm2 for “worst case” extraction and from 347 ± 30 pg E2 eq./dm2 to 1350 ± 70 pg E2 eq./dm2 for migration ...
Human psittacosis: a review with emphasis on surveillance in Belgium.
psittacosis in humans, mainly in persons in contact with birds in either the setting of occupational or companion bird exposure. Infection is associated with a range of clinical manifestations from asymptomatic ...
Development and validation of chromatographic methods for screening and subsequent quantification of suspected illegal antimicrobial drugs encountered on the Belgian market.
emergence of superbugs. Therefore, simple and accurate analytical methods are necessary, which are capable to detect and quantify a wide range of antimicrobials in suspected illegal products. In this work, ...
Global burden of intellectual disability resulting from dietary exposure to lead, 2015
estimates, default ranges were created for countries with no data which encompassed the values encountered elsewhere. Blood lead levels and IQ decrements were estimated using functions previously developed by ...
Pesticide residues in Tunisian table grapes and associated risk for consumer’s health
samples contained multiple residues (4 to 24 residues), with an average of 11.6 residues per sample. Individual concentrations of pesticides in grapes ranged from 0.01 to 5.86 mg kg−1. For at least one ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
detection in the range of 0.03–0.21 μg kg−1, and limit of quantification in the range of 0.09–0.48 μg kg−1), and precision (relative standard deviation (RSD) ≤ 12.9%), the analytical method was successfully ...
