Alberta Airsheds Council has prepared this 2021 Alberta Airsheds Air Quality Report to provide a summary of the air quality data that is monitored and collected in our province by Alberta’s Airsheds. This information is important to share with Albertans because air quality affects our health and our environment. Air Quality Reports — Alberta Airsheds… Continue Reading

The Calgary Region Airshed Zone is proud to present a guide explaining health effects and exposure reduction resources to wildfire smoke. Community Guide to Wildfire Smoke and Health Overview Over the past few years, residents of the Province of Alberta have experienced increased smoke exposure as a result of severe wildfires. This guide has been… Continue Reading

By Jim Shorey PM2.5 is Particulate Matter smaller than 2.5 microns in size. Particulate Matter such as wood smoke is often measured using the principle of Beta Radiation Attenuation and Nephelometer Light Scattering Detection. Looking at the flow diagram below, particulate is drawn into the Inlet via a vacuum pump.  The Inlet has a PM10… Continue Reading

Ozone Jim Shorey Ozone gas is commonly measured by instruments with UV Photometric Technology Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of an Ozone Analyzer. This unit includes an internal Air Sample Pump, which draws Ambient Air into the port labeled SAMPLE. Once the sample enters the sample… Continue Reading

NO-NO2-NOx Jim Shorey NO-NO2-NOx gases are commonly measured by instruments using Chemiluminescence. Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of a NOx Analyzer. This unit includes an internal Air Sample Pump, which draws Ambient Air into the port labeled as SAMPLE.  The next component shown as REACTION CHAMBER… Continue Reading

Hydrogen Sulfide, H2S Jim Shorey H2S gas is commonly measured by instruments using both UV fluorescence and a Heated Converter. Hydrogen Sulfide, H2S gas emissions are often a result from oil & gas production facilities. Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of an H2S Analyzer. This unit… Continue Reading

Sulphur Dioxide, SO2 Jim Shorey SO2 gas is commonly measured by instruments using Ultra Violet UV fluorescence. Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of an SO2 Analyzer. This unit includes an internal Air Sample Pump, which draws Ambient Air into the port labeled as SAMPLE. The next… Continue Reading

Technology behind the Data – Total Hydrocarbon Jim Shorey Hydrocarbon gas is commonly measured by instruments with a Flame Ionization Detector Looking at the schematic shown below in Figure 1-1, we see a basic diagram of a Flame Ionization Detector.  The FID detector requires both Air and Hydrogen to mix and be lit into a… Continue Reading

Technology behind the Data – Carbon Monoxide, CO By: Jim Shorey CO gas is commonly measured by instruments using Gas Filter Correlation GFC. Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of a CO Analyzer. This unit includes an internal Air Sample Pump, which draws Ambient Air into the… Continue Reading
