Roemer, M.G.M. (author), Klok, E.J. (author), Janssen, S.A. (author)Het is bekend dat tijdens hittegolven meer mensen overlijden dan gemiddeld. Dit is niet alleen het gevolg van de warmte zelf: ook verhoogde concentraties van luchtverontreinigende stoffen spelen een rol. Om hierin een beter inzicht te krijgen, is de fenomenologie van in het bijzonder ozon en PM10 tijdens hittegolven en warme dagen nader bekeken....article 2011

Thijsse, T.R. (author), Roemer, M.G.M. (author), van Oss, R.F. (author), TNO Milieu, Energie en Procesinnovatie (author)Results of C6-C12 hydrocarbon measurements at three sites in the southern part of The Netherlands, a polluted region in Western Europe, are presented. The measurements were carried out over the period March 1991-February 1997. The concentrations at the sites, with 100-150 km distance between them, are quite similar and they are predominantly...article 1999

Roemer, M.G.M. (author), TNO Milieu, Energie en Procesinnovatie (author)There is mounting evidence that emissions of NOx and VOC in various countries in Europe are decreasing over the last years. According to the EMEP emission inventory, NOx emissions decreased in the order of 10-20% during the period 1989 to 1994 in many countries in NW-Europe (EMEP, 1996). For NMVOC and CO reductions of 12-27% and 10-45%...report 1998

(author), TNO Milieu, Energie en Procesinnovatie (author)An intercomparison of nine chemical mechanisms (e.g. ADOM, CBM-IV, EMEP, RADM2) as used by 12 contributing groups was conducted. The results for three scenarios are presented covering remote situations with a net O3 loss of around 2.7 ppb (LAND and FREE) and a moderately polluted situation with O3 formation of around 100 ppb (PLUME1) over a 5...article 1998

Roemer, M.G.M. (author), TNO Milieu, Energie en Procesinnovatie (author)There is mounting evidence that the emissions of NOK and VOC in various countries in Europe are decreasing. According to the EMEP Emission Inventory NOK, NMVOC and CO emissions decreased from 1988 to 1995 with about 10-30 % in many countries in NW Europe (EMEP, 1996).conference paper 1998

(author), TNO Milieu, Energie en Procesinnovatie (author)It is a well known fact, based on observations and modelling studies, that there are large spatial gradients over Europe in ozone characteristics. These differences are caused by the differences in strength of the phenomena which determine the ozone concentration at a specific location: the precursor emissions and the resulting chemical...conference paper 1998

(author), Instituut voor Milieuwetenschappen TNO (author)Global changes in emissions of the non-greenhouse gases nitrogen oxides (N0x), Volatile Organic Compounds (VOCs) and carbon monoxide (CO), affect the concentrations of greenhouse gases, in particular of ozone. The chemical mechanisms causing these changes were investigated with a global two-dimensional model, and the greenhouse effect of...article 1994
