To obtain timely data for the purpose of air quality assessment, air quality trend reporting
and to meet the requirements for inclusion of the data in provincial and national air
quality databases, a 24-hour method of sampling and analyzing Volatile Organic
Compound (VOC) concentrations in ambient air is used. Commercially available VOC
gaseous samplers are used in this method.
This method is applicable for the measurement of VOC concentrations in ambient air in
the range of 0.01 to 20 parts per billion (ppb) range.
This method adheres to the requirements of the current Air Monitoring Directive (AMD)
drafted by Alberta Environment in 1989. In some cases the limits and specifications
exceed the requirements of the current AMD. 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.
