(author)In order to improve air quality and to lower nitrogen deposition, nitrogen oxide emissions from vessel engines must respect certain Tier norms to obtain the required Engine International Air Pollution Prevention (EIAPP) certificate for sailing. In this study emissions factors of nitrogen oxides (NOx) of vessels in the port of Rotterdam region...report 2022

(author)Background Pesticides can be transported from the site of application to homes via different routes and lead to exposure of residents, raising concerns regarding health effects. We built a deterministic model framework (OBOmod) to assess exposure of residents living near fields where pesticides are applied. Methods OBOmod connects five...article 2022

Velzeboer, I. (author), Blom, M.J. (author), Duyzer, J.H. (author)This report describes a study in which the air purifying efficiency of selected systems was investigated under realistic, reproducible laboratory conditions. The aim of this study was primarily to determine the potential of air-purifying plant systems (plants with ventilation systems) to remove particulate matter (PM) and volatile organic...report 2019

Although ultrafine particulate matter (UFP) is hypothesised to be particularly health relevant, the number of studies into personal UFP exposure is limited. Aim To increase insight where and when most UFP exposure occurs, in terms of exposure levels and peaks in microenvironments,...article 2017

(author), Energieonderzoek Centrum Nederland (author)The fluxes of nitrogen oxides and ozone still remain unclear above forests, due to a lack of good quality flux measurements and the unclear influence of chemical reactions between some compounds on fluxes and gradient. The atmosphere-biosphere exchanges of nitrogen oxides and ozone have been studied by taking concentration measurements of these...conference paper 2011

(author), Veenendaal, E.M. (author), Kabat, P. (author)Simulation of emissions of the greenhouse gas N2O from agricultural land is still a challenge. This is mainly due to its high temporal variability, with low background emissions and a few transient peaks. In this study, a first attempt was made to simulate observations of N2O fluxes with a daily time step from managed peat soils. We used a new...article 2011

(author)Nitric oxide (NO) fluxes to the atmosphere were determined from different soil types in coniferous forest and deciduous forest in the Netherlands. Dynamic chambers were used to determine the emission every week throughout a year. Forest type and soil texture are important parameters leading to large differences in fluxes between sites.
