Discuss in one paragraph how pump calibration is important in air sampling for proper enumeration of organisms and isokinetic sampling. Support your discussion with appropriate references.

Solution

Answer:

Depending on the specific situation and expected outcomes, sampling strategies differ. However pump calibration is important in air sampling for proper enumearation of organisms and isokinetic sampling.

The purpose of the air sampling should be clear before air sampling. The preparation and calibration of the equipment/pump etc are essential to obtain the appropriate sample media.

Pump calibration is important for environmental organisms and isokinetic sampling:

because to (i) aviod the filter jam as evidenced by any loose particulate

(ii) as the pressure and temperature of the atomosphere has significant effect on air sampling

(iii) to keep the filter at a good air flow

(iv) to point out the signs of wear or damage such as scoring, rifiling or a loose coupler

(v) to ensure that sample integrity is maintained and work practices, potentia interference etc. are appropriately controlled.
