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 ...
Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool
available in an in-house created reference database containing over 1,700 strains from the BCCM / IHEM fungal collection. Results: A total of 149 isolates including 18 yeasts and 131 filamentous fungi were ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
standard operating procedures for specimen preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical ...
