A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
with respect to the reference value. Since the mode of the distribution is closer to the reference value of 60 nm, a difference in analysis algorithm e.g. leading to exclusion of a fraction of the ...
Analyzing the airborne birch and grass pollen monitoring network in Belgium
Belgium. The interpolated values were compared to a reference dataset containing spatio-temporal distributions of daily surface airborne birch and grass pollen levels from the SILAM model (System for ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
birch pollen levels near the surface in Belgium is substantially high, with CV % values ranging between ~15% and ~35%. The parameters indicating the start and end of the season, however, are at least ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
concentrations of 13 pollen taxa measured by the Swisens Poleno Jupiter were compared to the measurements of the Hirst method. The highest intraseasonal correlation values between both methods were found for ...
The search for the best airborne pollen monitoring locations
Here we explore the network quality (i) and network coverage (ii) of the current five pollen monitoring stations in Belgium. As reference dataset we use the spatio-temporal distributions of daily surface ...
Assessing uncertainty in airborne birch pollen modelling
catkins-ripening temperature, CV % values of 50% and more are obtained when quantifying the variation of the modelled airborne birch pollen levels. These errors are in line with reported values from the current ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
intraseasonal correlation values between both methods were found for Betula, Fraxinus and Poaceae. While some pollen taxa showed similar seasonal kinetics but with scaling discrepancies, other pollen taxa ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical properties, including particle size, shape, and ...
A novel genotoxin-specific qPCR array based on the metabolically competent human HepaRG™ cell line as a rapid and reliable tool for improved in vitro hazard assessment
Keersmaecker; Rogiers, Vera; Tatyana Y. Doktorova Source: Archives of Toxicology (2018) Keywords: genotoxicity HepaRG In vitro screening mutagenicity qPCR array Toxicogenomics Abstract: Although the value of the ...
Scientific opinion on Malachite green in food
not registered for use in food-producing animals in the European Union. The European Commission requested EFSA to evaluate whether a reference point for action (RPA) of 2 lg/kg for the sum of MG and its ...
