To obtain timely data for the purpose of air quality assessment, air quality trend
reporting, air quality index reporting and to meet the requirements for inclusion of the
data in provincial and national air quality databases, a continuous method of analyzing
Carbon Monoxide (CO) concentrations in ambient air is used. This method is capable of
measurement updates at a rate of once every five minutes or faster. Readings from
instruments of this method enables the calculation of hourly averaged concentrations of
CO. Commercially available CO analyzers are used in the method.
This method is applicable to the measurement of CO concentrations in ambient air in the
range of 0.05 parts per million (ppm) to 50.0 parts per million (ppm).
This method adheres to the requirements of the current Air Monitoring Directive (AMD)
1989by Alberta Environment In some cases the limits and specifications exceed the
requirements of the current AMD and subsequent amendments ?which amendments?.
It should be considered that the current and any future amendments or drafts of the
AMD will be used as the benchmark for requirements and criteria for ambient air
monitoring practices conducted in the Province of Alberta. Information used to write this
procedure was also taken from sources identified in the reference section.
