Temperature-related changes in airborne allergenic pollen abundance and seasonality across the northern hemisphere: a retrospective data analysis

cumulative increases in Tmin (r=0·61, p=0·010). Similar results were observed for pollen season duration, but only for cumulative degree days (higher than the freezing point [0°C or 32°F]) for Tmax (r=0·53, ...

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 ...
