  • NOSA Aerosol Symposium 2008: Climate effects of aerosols

    Aerosol scientists in the Nordic countries and world-wide are invited to participate in a symposium in Oslo, Norway, on November 6-7, 2008, organised by the Department of Atmospheric and Climate Research at NILU, Norwegian Institute for Air Research. Keynote speakers are Andreas Stohl (NILU, Norway); Gunnar Myhre (CICERO, Norway); and Hannele Korhonen (University of ...

  • Experimental evaluation of Aerosol concentrators

    Introduction An aerosol concentrator is a vital component of any front-end sampling module used to introduce aerosol particles to a chemical or biological identification sensor (Hart et al, 2000). Because these sensors need to have a minimum amount of sample to make a positive identification, particle concentration is often necessary, making it critical to know the concentration factor of ...

  • NOSA aerosol symposium 2002

    Nordic Society for Aerosol Research (NOSA) Aerosol Syposium will be held at NILU, Kjeller (Oslo), Norway 7-8 November 2002. A special focus on Organic Aerosol, soot, and modelling of ...

  • The aerosol–cloud–climate conundrum

    The complexity of the atmospheric aerosol and its connection with clouds and climate are illustrated with a host of examples against the background of our present limited state of understanding. A discussion of related feedbacks demonstrates the difficulties of resolving all respective research issues. The key role of aerosols and clouds in anthropogenic climate change make the high uncertainties ...

  • The greening of aerosol propellants

    Chemviron Carbon have pioneered the use of specially selected activated carbons for the storage and delivery of compressed aerial gases such as carbon dioxide and nitrogen. There are many potential gas storage/delivery applications relating to this technology, including as an environmentally friendly alternative to traditional aerosol propellants - see attached article. The technique can also ...

  • Global aerosols studied by NILU

    Aerosols scatter and absorb solar radiation and thereby influence the radiation in the atmosphere and the global climate. To understand the climate system and the ongoing climate change it is important to know the distribution of aerosols in the atmosphere. Satellites provide an extremely useful tool to study this distribution, especially since it is very inhomogeneous with respect to ...

  • Aerosol filtration in nanofiber filter media

    Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop  is required.  Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...

  • Determining saccharidic tracers in atmospheric aerosols

    Atmosperic aerosols have a strong impact on the climate. Within the organic aerosol fraction, anhydrosugars and sugar alcohols are valuable tracers for biomass burning and biogenic sources. They are best determined by ion chromatography coupled to pulsed amperometric detection. Sample preparation merely involves a simple waterextraction. Detection limits are in the ng/m3 ...

  • Characterization of ambient aerosols in Northern Thailand and their probable sources

    The present study examines variation of ambient aerosol mass and number concentrations in Chiang Mai, Thailand during winter. Aerosol particle samples were collected and measured at four different sites, representative of urban, industrial, residential and rural areas during daytime between December 2003 and January 2004. Average 10 h particulate matter (PM) mass concentrations were found to be ...

  • Bibliometric analysis of aerosol research in meteorology and atmospheric sciences

    A bibliometric method was developed to investigate the aerosol research based on the papers from 1991 to 2009 in Science Citation Index Expanded, the Thomson Reuters. The analysed aspects covered scientific output and citation tracking on the basis of journal patterns; country; institute and author research performances. Improved indicators Peak–Year Citation per Publication and Relative ...

  • Modelling changes of aerosol compositions over Belgium and Europe

    Seasonal changes in aerosol compositions over Belgium and Europe are simulated with an extended version of the EUROS model. EUROS is capable of modelling mass and chemical composition of aerosols in two size fractions (PM2.5 and PM10-2.5). The chemical composition is expressed in terms of seven components: ammonium, nitrate, sulphate, primary inorganic compounds, elementary carbon, primary ...

  • Removal of VOCs from Spent Aerosol Cans.

    There are over three billion aerosol cans manufactured in the U.S. annually, 60% of which are consumed by households. Many of the products contained in these cans, such as paint products, light lubricants, starting fluids, polishes and waxes, and cleaners, contain substantial amounts of volatile organic compounds (VOCs) as solvents and include flammable propellants. As a result, partially empty ...


  • Environmental and human health risks of aerosolized silver nanoparticles

    Silver nanoparticles (AgNPs) are gaining attention from the academic and regulatory communities, not only because of their antimicrobial effects and subsequent product applications, but also because of their potential health and environmental risks. Whereas AgNPs in the aqueous phase are under intensive study, those in the atmosphere have been largely overlooked, although it is well established ...

  • Aerosol characteristics at a continental urban station in southern India

    Spectral Aerosol Optical Depth (AOD), Black Carbon (BC) mass concentration and Suspended Particulate Matter (SPM) measurements were made at an urban continental location, Bangalore (13°N, 77.6°E), in southern India. These results show that AODs reach a maximum during April (∼0.5) and minimum during December (∼0.2) at 500 nm. BC and SPM showed variations of 0.6-4.2 μg m³ and 120-195 μg m³, ...

  • A high-performance aerosol concentrator for biological agent detection

    Introduction Particle sampling from ambient air is a well-developed technology described in many texts (e.g., Vincent 1989; Willeke and Baron 1993; Hinds 1999). However, there are many cases in which the concentration of airborne particles is so low that it becomes necessary to sample for extended periods of time to collect enough mass for chemical or biological characterization of the ...

  • Atmospheric aerosols behaviour at an industrial area in Northern France

    Aerosols samplings by bulk filtration and by use of a high volume cascade impactor were performed taking into account wind directions simultaneously at an urban and a rural site in Northern France. Fifteen major and trace species were considered to study characteristics of the particles collected. Evolution of the Weighted Mean Diameter vs. the wind direction, profiles of the Mass Size Function ...

  • Modelling of aerosol in the Greater Athens Area, Greece

    Aerosols have recently been defined as a serious atmospheric pollution problem in the Greater Athens Area (GAA). This research is mainly focused on assessing the PM10 concentration levels in the GAA atmosphere through simulations. The model results of the chemical constituents of PM10 are satisfactory comparing to measurements; the discrepancies are attributed to the re-suspended and seaborne ...
