A numerical analysis of the aspiration efficiency of a personal sampler

The impact on sampling efficiency of increasing the flow rate of a low flow personal sampler has been examined. Increases in flow rates were required to obtain sufficient particle mass over the duration of a typical rush hour commute (3.5?16.7 litres/min). Computational Fluid Dynamics (CFD) modelling has been used to assess the implications of this higher flow on the aspiration efficiency of the ...

Exposure to environmental tobacco smoke at work, at home, and during leisure time: personal exposure measurements by diffusive sampling of airborne 3-Ethenylpyridine

Environmental tobacco smoke (ETS) is associated with an increased risk of several diseases. In 2002, the ETS exposure level was studied in a Finnish cross-sectional population sample with a sub-sample of currently working nonsmokers. In all, 123 nonsmokers (25-64 years) reporting at least 1 h of daily exposure to ETS participated in personal exposure measurements. Two 3 M organic vapor monitors, ...

Indoor air quality in primary schools

The indoor air quality (IAQ) in classrooms is expected to play a key role in the assessment of the effects of the children's personal exposure to air pollution since they spend on average 7–11 h per weekday at school. A statistical treatment was conducted over a database of indoor air parameters and the primary schools where these parameters were sampled (urban area of Lisbon, Portugal). The aim ...

The Spectrex air sampler ideal for industrial hygiene.

Comments by an industrial hygiene supervisor in Texas "The Spectrex PAS-500 is a great tool for collecting both personal and area air samples. I have yet to have a worker complain about having to wear the pump. The workers appreciate the drastic reduction of weight and size when compared to the traditional low volume pumps. The best advantage of the PAS-500 is the clip that holds the pump ...

Remote monitoring of Indoor Air Quality (IAQ)

Indoor air quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort, or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”. Remote monitoring of IAQ sampling data collected by PPM ...

Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer

Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton XRF analyzer. Three separate 60-second readings are ...

Screening technique to estimate high benzo[a]pyrene concentrations near roads

The emission factors of benzo[a]pyrene for gasoline cars and for diesel cars were measured by directly collecting the exhaust gas using a portable sampling equipment and became 660 ng km–1 and 1700 ng km–1, respectively. The regression equations to easily evaluate the concentrations at the roadsides and at the crossroads were introduced as the functions of building height, road width, ...
