Method development for analysis of nanoplastics in drinking water and milk using transmission electron microscopy (TEM)
expanded measurement uncertainties for median size and shape measuments of pristine NP s ranged from 2.5 — 7.5 % and 3.0 — 8.9 %, respectively, setting a reliable baseline for further studies. As a next ...
Advancing automated identification of airborne fungal spores: Guidelines for cultivation and reference dataset creation
study, part of SYLVA and COST Action ADOPT, addresses these gaps by establishing best practices for cultivating reference material and creating tailored datasets. Seventeen fungal species were tested on ...
A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
Copenhagen, Denmark (2024) Keywords: Metrology nanoplastics TEM uncertainty Validation study Abstract: The spread of plastics in the environment has led to the formation of microplastics (MP s) and even smaller ...
What drives the long-term changes in airborne birch and grass pollen levels in Belgium?
birch pollen and ~15% to grass pollen. Future climate and land-use changes may exacerbate this issue by increasing the amount of allergenic pollen in the air and prolonging pollen seasons. This study aims ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
input data and ECMWF ERA5 meteorological data. The relative Coefficient of Variation (CV %) is used as a measure for uncertainty. The studied key model input datasets that drive the birch pollen ...
First European pollen reanalysis for allergenic trees
long-term assessment of pollen abundance in the air is therefore useful for epidemiological studies, to track the biodiversity and ecosystem evolution, and may also help to estimate the species migration ...
Modelling grass pollen load in temperate and Mediterranean European areas based on source spatial distribution
causes of pollen allergy worldwide. Still, the identification of its specific emission sources is a challenging task because of the ubiquitous nature of this pollen type. Previous studies have explored the ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
offline method can only provide results retrospectively, from 1 day to 1 week, and previous evaluation studies have shown certain limitations in terms of sampling efficiency and measurement accuracy. ...
Metabarcoding and metagenomics techniques in monitoring airborne pollen
obtained in the previous ones, however they are still little used in aerobiology. This study presents a review and the state of the art of airborne pollen studies based on metabarcoding and metagenomics, as ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
the standard Hirst method with a volumetric spore trap. However, this offline method can only provide results retrospectively, from 1 day to 1 week, and previous evaluation studies have shown certain ...
