(author), van der Gon, H.D. (author), Manders-Groot, A.M.M. (author), Raaschou-Nielsen, O. (author)The integrated model system DEHM/UBM/AirGIS, developed at Aarhus University, Department of Environmental Science, has been extended with the dynamic aerosol module M7 to account for particle number concentrations of particles with diameters below 1 μm in the atmosphere. The aim of this development is to quantify the spatial and temporal...article 2021

(author)Modelling of ambient particle number concentrations (PNC) has been implemented in the Danish air quality modelling system DEHM/UBM/AirGIS and evaluated with long-term measurements. We implemented particle dynamical processes in the regional scale model DEHM using the M7 aerosol dynamics module (presented in the accompanying article by Frohn et...article 2021

John, A.C. (author), Küpper, M. (author), Manders-Groot, A.M.M. (author), Debray, B. (author), Lacome, J.M. (author), Kuhlbusch, T.A.J. (author)In spite of the still increasing number of engineered nanomaterial (ENM) applications, large knowledge gaps exist with respect to their environmental fate, especially after release into air. This review aims to summarize the current knowledge of emissions and behavior of airborne engineered nanomaterials. The whole ENM lifecycle is considered...article 2017

Keuken, M.P. (author), Moerman, M. (author), Zandveld, P. (author), Henzing, J.S. (author)Total and size-resolved particle number and black carbon concentrations were investigated in urban areas of the city of Rotterdam (the Netherlands) situated near an industrial area. Several monitoring campaigns were conducted in the period 2011-2014 at three local locations and at a regional background site. Black carbon levels showed minor...article 2015

Keuken, M.P. (author), Moerman, M. (author), Zandveld, P. (author), Henzing, J.S. (author), Hoek, G. (author)The presence of black carbon, and size-resolved and total particle number concentrations (PNC) were investigated in the vicinity of Schiphol airport in the Netherlands, the fourth busiest airport in Europe. Continuous measurements were conducted between March and May 2014at Adamse Bos, located 7km from Schiphol, and in 2012at Cabauw, a regional...article 2015

Beurskens-Comuth, P.A.W.V. (author), Verbist, K. (author), Brouwer, D. (author), TNO Kwaliteit van Leven (author)Objectives: There is a growing awareness of the potential risks for human health of exposure to ultrafine particles or nanoparticles. In that context, workplace air measurements become important, and various strategies have been developed to monitor exposure. In addition, observations and time/activity registrations are part of the exposure...article 2011

Brouwer, D.H. (author), Gijsbers, J.H.J. (author), Lurvink, M.W.M. (author), TNO Voeding (author)Recently, toxicological and epidemiological studies on health effects related to particle exposure suggest that 'ultrafine particles' (particles with an aerodynamic diameter of <100 nm) may cause severe health effects after inhalation. Although the toxicological mechanisms for these effects have not yet been explained, it is apparent that...article 2004
