de Weger, L.A., Verbeek, C., Markey, E., O’Connor, D.J. & Gosling, W.D. (2024) Greater difference between airborne and flower pollen chemistry, than between pollen collected across a pollution gradient in the Netherlands. Science of The Total Environment 172963. DOI: 10.1016/j.scitotenv.2024.172963
Luckily, in spite of these trying times, we are allowed to continue our research in Amsterdam and on the Veluwe to determine the effects of air pollution on airborne pollen grains. Unfortunately for us (but generally perhaps one of the few silver linings of this situation), the COVID-19 lockdown has largely eliminated our main variable of interest; air pollution.
With traffic in the city at a minimum, any chemical differences might not be as pronounced between the city and rural areas. However, this may actually provide us with a unique opportunity to get a baseline of the pollen chemistry in Amsterdam with relatively little pollution. This baseline may also be of interest to projects working on urban air quality and greenifying urban spaces, such as the projects in the Amsterdam Knowledge Mile Park, which is included amongst our sampling locations.

On Wednesday I visited Dr. Letty de Weger at the Leiden University Medical Centrum to discuss pollen and see her facilities for monitoring pollen in the environment. Super exciting discussions and a beautiful day to be up on the roof!
