In Eindhoven wordt op een groot aantal locaties de luchtkwaliteit gemeten met sensorsystemen die door ECN ontwikkeld zijn. Tezamen vormen deze systemen het Innovatie Lucht Meetnet (ILM). Het meetnet is gestart in 2014 en de afgelopen jaren zijn aantallen stations en te bemeten componenten verder uitgebreid. De belangrijkste componenten die nu...

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...

European Committee for Standardisation (CEN) Technical Committee 264 ‘Air Quality’ has recently produced a standard method for the measurements of anions and cations in PM2.5 within its Working Group 34 in response to the requirements of European Directive 2008/50/EC. It is expected that this method will be used in future by all Member States...

Results: The exploratory analysis showed that the variability in the ILM PM data increased from 10% to 16% (coefficient of variation) between 2013 and 2015 The ILM data tended to record lower values than the LML data, although the peaks and troughs were still observed. The 10-minute data were typically too noisy to allow the identification of...

Door nieuwe wetenschappelijke inzichten en innovatieve meettechnieken is een aanpassing van de bestaande monitoring van luchtkwaliteit met een netwerk mogelijk en wellicht gewenst. Toxicologische en epidemiologische studies laten zien dat het meten van andere componenten (dan PM10 en PM2.5) en eigenschappen van fijnstofdeeltjes ook van belang...

Directive 2008/50/EC on ambient air quality and Cleaner Air for Europe set limit values for particulate matter PM10 and fine particulate matter PM2.5. The reference measurement methods have already been standardized by CEN, the European Committee for Standardization (EN 12341:1998 and EN 14907:2005 ). Both methods are currently under revision...

Ambient air monitoring as part of the US Environmental Protection Agency’s (US EPA’s) Clean Air Status and Trends Network (CASTNet) currently uses filter packs to measure weekly integrated concentrations. The US EPA is interested in supplementing CASTNet with semi-continuous monitoring systems at select sites to characterize atmospheric...

During recent years ECN developed high quality sensors for pollutants in ambient air. Currently developed sensors for PM2.5, PM10 and NO2 are applied for third parties. Field of application are urban air quality and emission monitoring from transit storage and handling of dry bulk like ore and coal. Low cost high quality sensors are of...

Concentraties van reactief fijnstof kunnen snel veranderen, aangezien de bronnen vaak diffuus of mobiel zijn. Als de concentraties na uren of dagen bepaald zijn, kan de bron allang vervlogen zijn. Dat maakt het invoeren van emissiebeperkende maatregelen én controle daarop lastig. Een nieuwe, continue meetmethode voor het oxidatieve...

Abstract. Real-time measurements of ambient concentrations of gas-phase ammonia (NH3) were performed in Barcelona (NE Spain) in summer between May and September 2011. Two measurement sites were selected: one in an urban background traffic-influenced area (UB) and the other in the historical city centre (CC). Levels of NH3 were higher at CC (5.6...
