ten Brink, H.M. (author), Hitzenberger, R. (author), Virkkula, A. (author)Air pollution by diesel traffic became a concern in the UK in the 1950s. Exposure levels were assessed via probing the light absorption of filter samples, which was translated to a mass concentration of “diesel smoke” (DS), based on the results of a measurements in the exhaust of a test diesel engine. We convert these DS values to concen...article 2022

ten Brink, H.M. (author), Otjes, R.P. (author), Weijers, E.P. (author), Henzing, B. (author)The visibility on New Year's nights in the Netherlands is low during stagnant weather. This is due to the scattering and absorption of light by the aerosol-smoke from the ?reworks. We made an assessment of the responsible aerosol-species. The investigation took place during the New Year's night of 2009. Measurements were made at a regional site...article 2017

(author)We measured the radiocarbon (14C) content of organic carbon (OC) samples from two locations in the Netherlands, the urban location of Amsterdam and the coastal location of Petten. PM10 samples were collected in Amsterdam and total suspended particles were collected in Petten using high volume samplers. The 14C/12C fraction in the samples is...article 2013

(author)The magnitude of the regional first Aerosol Indirect forcing Effect (AIE) was addressed. This is the increase in reflectivity of clouds due to manmade aerosol. Two approaches were followed: 1) modelling using generic knowledge on the interaction of aerosol and cloud, and 2) an experimental study on the importance of a specific regional aerosol,...other 2012

(author), Atkinson, R.W. (author), Anderson, H.R. (author), Cassee, F.R. (author)Background: Current air quality standards for particulate matter use the PM mass concentration (PM10 or PM2.5) as a metric. It has been suggested that particles from combustion sources are more health relevant than particles from other sources, but the impact of policies directed at reducing particles from combustion processes is usually...article 2011

Energieonderzoek Centrum Nederland (author), ten Brink, H.M. (author), Weijers, E.P. (author), Röckmann, T. (author), Dusek, U. (author)We tested the feasibility of 14C analysis of carbon in PM in the Netherlands. This allows a first assessment of the sources of the carbon: PM-carbon that derives from modern sources has a 14C content similar to that of atmospheric carbon dioxide, while carbon that comes from (incomplete combustion) of fossil fuel does not contain 14C. Twenty...report 2010

The study further discusses possible consequences of the presence of PM2.5 in ambient air for the (urban) climate and human health. The work was executed in assignment of the DCMR...report 2010

In the evaluation we focused on the data in the smallest aerosol, that is, in particles with an (aerodynamic) diameter smaller than 0.18 &#181;m. The average ratio of nitrate to sulphate in this range was 0.6. The nitrate was present in the form of the semi...article 2009
