The Belgian health examination survey: objectives, design and methods.
the BELHES until a predefined number ( = 1100) was reached. To obtain the required sample size, 4918 eligible BHIS participants had to be contacted. Data were collected at the participant’s home by ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
spectrometry (spICP- MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the critical factors that determine the measurement of the particle size distribution by TEM. ...
Is the European Health Interview Survey online yet? Response and net sample composition of a web-based data collection.
the sole mode. In the context of future EHIS, the response rate and net sample composition of a web-only approach was tested. METHODS: A Belgian study with a target sample size of 1000 (age: 16-85) was ...
Confronting Risk of Bias in RF Bioeffects Research. Comments on Two Papers by Vijayalaxmi and Prihoda
4. sham exposures. They also examined study outcomes, i.e., whether or not studies reported statistically significant effects of exposure, and effect size (Cohen’s d, the sample estimate of the ...
Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products
the size distribution compared to the size distribution obtained from transmission electron microscopy. Depending on the sample and the background silver concentration, particles with an equivalent ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
sample preparation, analysis and data interpretation were unraveled. The expanded measurement uncertainty for AgNP sizing was calculated to be 16% in E174-containing food products and increased up to 23% ...

Nanoparticles physico-chemical characterization transmission electron microscopy Abstract: Scope of this workshop Training on the measurement approach for the physicochemical characterization of nano-sized ...
Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?
samples of E174 and ten food items containing E174 were investigated for their number-based size distribution of Ag particles. The food items were as well investigated for their total Ag content. Single ...
