Evaluation of a personal and microenvironmental aerosol speciation sampler (PMASS).
In this study, an all-aluminum sampler was reconfigured to a lighter weight by using plastic for structural components not contacted by aerosol. Because the sampler body was made of plastic, the aluminum size-selective cyclone inlet was redesigned into a separate, removable unit. The resulting personal and microenvironmental aerosol speciation sampler (PMASS*) is a small, compact sampler design...
متن کاملA collaborative European study of personal inhalable aerosol sampler performance.
Following the adoption of new international sampling conventions for inhalable, thoracic and respirable aerosol fractions, a working group of Comité Européen de Normalisation (CEN) drafted a standard for the performance of workplace aerosol sampling instruments. The present study was set up to verify the experimental, statistical and mathematical procedures recommended in the draft performance ...
متن کاملImproving the UNC Passive Aerosol Sampler Model Based on Comparison with Commonly Used Aerosol Sampling Methods
Objectives In an occupational environment, passive sampling could be an alternative to active sampling with pumps for sampling of dust. One passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). It is often analysed by microscopic imaging. Promising results have been shown for particles above 2.5 µm, but indicate large underestimations for PM2.5. The aim of t...
متن کاملDevelopment and evaluation of an ultrasonic personal aerosol sampler
Assessing personal exposure to air pollution has long proven challenging due to technological limitations posed by the samplers themselves. Historically, wearable aerosol monitors have proven to be expensive, noisy, and burdensome. The objective of this work was to develop a new type of wearable monitor, an ultrasonic personal aerosol sampler (UPAS), to overcome many of the technological limita...
متن کاملThe pre-impinger, a selective aerosol sampler.
When airborne particles are inhaled it is known that most of those of effective diameter greater than about 5 ,u are filtered out by the upper respiratory tract. Current knowledge of this subject as reviewed by Davies (1949, 1952) indicates that the size of particle which has a 50% chance of passing through the upper respiratory tract lies somewhere in the range 312t to 5 t±. Toxic effects from...
