Field Dynamic Calibration of SO2 Recording Instruments

Recent air pollution legislation, introduced as a Clean Air Act into New South Wales, the most populous and most heavily industrialized Australian State relies mainly upon the establishment of maximum limits of emission of air impurities. Regulations made under the Act set out the first of a series of such limits which cover the more commonly encountered pollutants. Other limits will be included later as knowledge is accumulated but, in the meantime, where standards have not been fixed the "best practicable means" of controlling air pollution must be used. To facilitate administration and to provide financial support for scientific and engineering services in the form of the Air Pollution Control Board, industries of significant air pollution potential have been designated as scheduled premises and pay annual license fees. Further technical support for the legislation is provided by an Air Pollution Advisory Committee.
