The Grimm particulate monitor is used by Alberta Environment (AENV) in the
Mobile Air Monitoring Laboratory (MAML). This monitor is used to collect real
time particulate data, which will indicate the approximate levels of PM10, PM2.5
and PM1 during emergency response events. This data is not included in
provincial or national air quality databases. This method is capable of
measurement updates at a rate of once every minute or faster.
This method adheres to the requirements of the current Air Monitoring Directive
(AMD) drafted by AENV 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.
