Definition

  • The ANALYSIS AND AIR QUALITY DIVISION analyses a variety of samples, primarily ambient air samples but also including samples from industrial sources, wastes and effluents. Divisional staff developed analytical methods for regulations and quality assurance programs suitable to specific sample types to assist in developing and implementing departmental regulations. The Division also coordinates the operation of the federal provincial National Air Pollution Surveillance (NAPS) Network. The NAPS network consists of almost 400 monitoring instruments located at 140 sites in 52 major urban areas across Canada. Pollution measurement methodologies for ambient air, both in situ and laboratory, are developed and evaluated in support of the NAPS network. Research is also undertaken in assessing trends in major air pollutants. To support these two major thrusts, the division?s labs specialize in Volatile Organic Compounds (VOC) analysis, polycyclic aromatic hydrocarbons (PAH), dioxins an d nitro-PAH compounds using high-resolution GC-MS (gas chromatography-mass spectroscopy), metals and elements by X-ray fluorescence spectroscopy, and ions by ion chromatography and capillary electrophoresis. Research is conducted into new techniques, especially applications of MAP? (Microwave Assisted Process), GC-AED (Atomic Emission Detector), identification of volatile compounds in air, vehicle exhausts, and applications of capillary electrophoresis and GC-MS.
