Instruments for Air Pollution Measurement,e mass concentration, is required to assess the significance of the pollution; the soiling effect of the pollutant should also be determined. The possibilities of using light obscuring and corrosion effects are examined. Finally, the interrelationship between objectives of a study and measuring techniques to be used is emphasized.
