  • Size distribution of the secondary organic aerosol particles from the photooxidation of toluene

    In a smog chamber, the photooxidation of toluene was initiated by hydroxyl radical (OH·) under different experimental conditions. The size distribution of secondary organic aerosol (SOA) particles from the above reaction was measured using aerodynamic particle sizer spectrometer. It was found from our experimental results that the number of SOA particles increased with increasing the ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • European On-Line Particle Mass Spectrometry

    An international workshop on European On-line Particle Mass Spectrometry (PMS) was held 29th-30th of November 2005 at the JRC in Ispra, Italy. The main goals of the Workshop were: 1) To get together all European scientists involved in the field of PMS 2) To review the latest scientific progress on the field of PMS, with particular emphasis on:a. New instrumentationsb. Data analysisc. ...


  • 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 ...

  • In-Vehicle exposures to particulate matter and black carbon

    ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...
