(author), Energieonderzoek Centrum Nederland (author)Abstract Background The RUPIOH study, an EU-funded multicentre study, was designed to examine the distribution of various ambient particle metrics in four European cities (Helsinki, Athens, Amsterdam, Birmingham) and assess their health effects in subjects with asthma or COPD, based on a more detailed exposure assessment. Methods At each centre...report 2012

(author), TNO Kwaliteit van Leven (author)The significance of engineered nanomaterials (ENM) and nanotechnologies grows rapidly. Nanotechnology applications may have a positive marked impact on many aspects of on human every day life, for example by providing means for the production of clean energy and pure drinking water. Hundreds of consumer nano-based products are already on the...article 2010

(author), Lianou, M. (author), Vallius, M. (author), Chalbot, M.-C. (author)The associations between residential outdoor and ambient particle mass, fine particle absorbance, particle number (PN) concentrations, and residential and traffic determinants were investigated in four European urban areas (Helsinki, Athens, Amsterdam, and Birmingham). A total of 152 nonsmoking participants with respiratory diseases, not exposed...article 2008

(author)The number of ultrafine particles in urban air may be more health relevant than the usually measured mass of particles smaller than 2.5 or 10 mm. Epidemiological studies typically assess exposure by measurements at a central site. Limited information is available about how well measurements at a central site reflect exposure to ultrafine...article 2008

Epidemiological time series studies typically use a central site to characterize human exposure to outdoor air pollution. There is currently very limited information how well measurements at a...article 2007
