Time Integrated Monitoring

WBEA uses integrated sampling methods, including canisters, for measurement of volatile organic compounds (VOCs) and reduced sulphur compounds (RSCs); PUF/XAD2 sandwich cartridges for 23 species of polycyclic aromatic hydrocarbons (PAH); Federal Referenced Method (FRM) for PM2.5 and PM10; and MIC collectorsfor precipitation chemistry. WBEA is currently using VOC and PAH standard operating protocols established by Environment Canada and the USEPA.

Specialized instruments and analyzers are also in operation. Trace (sub parts per billion) NOX and NH3 analyzers improve the understanding of photochemical reactions and aerosol formation. Dicot samplers co-measure fine and course particulate matter (PM2.5 and PM10-2.5). Dichot filters are then analyzed by XRF and/or ICP-MS for determination of PM chemical speciation. An ambient ion monitor determines concentrations of NH3, HNO2, HNO3, SO2 and anions and cations of PM2.5 in ambient air.
