New Measurement Technique of Expiratory Air Flow Rate Using Miniatured Air Chamber

air pollution effects on peak expiratory flow rate in children

airway mucus hypersecretion health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. the aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

Air-Solids Flow Measurement Using Electrostatic Techniques

Flow rate measurement in modern ambient air samplers – how accurate ?

New generation ambient air samplers operate at much lower sampling flow rates than do their “high volume” predecessors, namely 16.7 liters/minute. When these new air samplers emerged several years ago there were limited tools available with which to assess and calibrate their operating flow rate. In 1996 a flow meter specifically designed for these new air samplers came available, known as the ...
