Sweden Front cover: Electrone microscope image of a diesel exhaust particle agglomerate.Till Cicci, Erica och Arvid " Every animal is naturally made for the use of pure, natural and free air " Tests of the effects of air on the human body, John Arbuthnot.ABSTRACT Exhaust emissions from mobile sources is one of the major sources to air pollution. Thus, it is important to identify and quantify ch...

Several collocated semicontinuous instruments measuring particulate matter with particle sizes < or =2.5 microm (PM2.5) sulfate (SO4(2-)) and nitrate (NO3-) were intercompared during two intensive field campaigns as part of the PM2.5 Technology Assessment and Characterization Study. The summer 2001 urban campaign in Queens, NY, and the summer 2002 rural campaign in upstate New York (Whiteface M...

Optical-biogeochemical relationships of particulate and dissolved organic matter are presented in support of remote sensing of the Baltic Sea pelagic. This system exhibits strong seasonality in phytoplankton community composition and wide gradients of chromophoric dissolved organic matter (CDOM), properties which are poorly handled by existing remote sensing algorithms. Absorption and scatterin...

This study is focused on the emission of fixed bed combustor batch operated. Real-time analyser ELPI (electrical low-pressure impactor) system was used to size-segregated particulate matter emission ranging from 40 nm to 10 μm. The results show that total number concentration were 3.4 × 10(3), 1.6 × 10(4), and 1.5 × 10(5) particles/cm(3) · kg(fuel), while total mass of particles were 12.2, 8.0,...

This paper presents the design and performance of a compact dilution sampler (CDS) for characterizing fine particle emissions from stationary sources. The sampler is described, along with the methodology adopted for its use. Dilution sampling has a number of advantages, including source emissions that are measured under conditions simulating stack gas entry and mixing in the ambient atmosphere....

An analysis was made of airborne solid particulate matter in Córdoba, a city in the southwestern Iberian Peninsula with a Mediterranean climate. The detection and analysis techniques used enabled solid particles to be classified by size, by biogenic or non-biogenic origin, and by natural source of emission, e.g. pollen grains released by vascular plants during the pollen season, or particles at...
