Air Monitoring

Air monitoring measures the quantity of airborne fibres in any given environment.  There are a few different types of monitoring to suit different situations, some of which are outlined below.  The methodology is roughly the same in each instance.  A pump is connected to a filter head by tubing. The pump maintains a steady flow, pulling air through a filter mounted in the filter head. After a given period of time a certain volume of air can said to have been sampled.  The filter is removed and examined for ‘respirable’ fibres under a microscope.  The number of fibres counted and the volume of air sampled lead to the calculation of a concentration of airborne fibre – most often expressed as fibres per millilitres of air (f/ml).
