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… Show more
Technology behind the Data – PM2.5 Particulate
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… Show more
Technology Behind the Data – Ozone
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… Show more
Technology Behind The Data – NO – NO2 – N0x
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… Show more
Technology Behind the Data – Hydrogen Sulfide, H2S
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… Show more
Technology Behind The Data – Sulphur Dioxide, SO2
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… Show more
Technology Behind the Data – Total Hydrocarbon
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… Show more
Technology Behind The Data – Carbon Monoxide
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… Show more
Launch of Lafarge Canada Inc. Idle-Free Reduction Policy
For over a decade Lafarge Canada Inc. (Lafarge) has been a part of a Western Canada wide anti-idling campaign. This campaign occurred across all of Lafarge’s operations and included not only Lafarge employees but contractors working on behalf of Lafarge. The purpose of the campaign was to recognize that air quality is everyone’s responsibility and… Show more
