Effects of tree pollen on throughfall element fluxes in European forests
which are part of the ICP Forests Level II network. The SPI n for the dominant tree genus was observed at 56 aerobiological monitoring stations in nearby cities. The net contribution of pollen was ...
Long-Term Pollen Monitoring in the Benelux: Evaluation of Allergenic Pollen Levels and Temporal Variations of Pollen Seasons
locations. The dynamics in the observed trends can impact allergic patients by increasing the severity of symptoms, upsetting the habit of timing of the season, complicating diagnosis due to overlapping pollen ...
Residential green space and medication sales for childhood asthma: A longitudinal ecological study in Belgium
of grassland and garden were observed (unadjusted parameter estimates per IQR increase of relative cover, range across four strata: grassland, β = 0.15–0.17; garden, β = 0.13–0.17). The associations ...
Spatio-temporal monitoring and modelling of birch pollen levels in Belgium
Catherine Linard; Marijke Hendrickx; Sofiev, Mikhail; Andy W. Delcloo Source: Aerobiologia (2019) Keywords: Birch fraction maps Birch pollen Pollen observations SILAM model Time series Abstract: In Belgium, ...
Temperature-related changes in airborne allergenic pollen abundance and seasonality across the northern hemisphere: a retrospective data analysis
specific climate-related links to any observed changes. Methods For this retrospective data analysis, we did an extensive search for global datasets with 20 years or more of airborne pollen data that ...
Thirty-four years of pollen monitoring: an evaluation of the temporal variation of pollen seasons in Belgium
the concentration threshold of 80 pollen grains/m3 was clearly observed. Concerning temporal variations, the pollen season has tended to end earlier for birch, ash and plane and the peak concentration ...
Relationships between aeroallergen levels and hospital admissions for asthma in the Brussels-Capital Region: a daily time series analysis.
Van Nieuwenhuyse Source: Environ Health, Volume 17, Issue 1 (2018) Abstract: BACKGROUND: Outdoor pollen grain and fungal spore concentrations have been associated with severe asthma exacerbations at the ...
Comparative long-term trend analysis of daily weather conditions with daily pollen concentrations in Brussels, Belgium.
meteorological conditions by using long-term daily datasets of 11 pollen types (8 trees and 3 herbaceous plants) and 10 meteorological parameters observed in Brussels between 1982 and 2015. Furthermore, we ...
A statistical model for predicting the inter-annual variability of birch pollen abundance in Northern and North-Eastern Europe.
Severova, Elena; Lucie Hoebeke; Ramfjord, Hallvard Source: Sci Total Environ, Volume 615, p.228-239 (2017) Abstract: The paper suggests a methodology for predicting next-year seasonal pollen index (SPI, a sum ...
Dietary exposure to pyrrolizidine alkaloids in young children and adults from the Belgian population (PASFOOD)
matrix. The PA s observed in positive samples among the Belgian honeys were in agreement with the recurrent flora in the country. Honey based sweets & snacks were barely contaminated. In contrast with ...
