WBEAPassive Sampler Validation Study

for NH3 and HNO3• Compare Ogawa and Radiello PS with ADS• Use the following specific adsorbing material:

• Sodium chloride and Nylon for HNO3• Citric and phosphorous acid for NH3

• Assess DL, precision & accuracy at 2 sites:• AMS01 Fort McKay (FMK),• AMS06 Fort McMurray (FMM)

• Expose monthly for total 5 months• Start on June 1 , 2011

Lab Blank

Denuders, EI and FP are shipped separately and assembled in field prior to sampling. Field Blanks are treated like samples except that they remain unexposed. ADS inlets (EI1 and EI2) are positioned at exact same height above ground as the PS units. With each monthly shipment one set of Lab Blanks is prepared and stored in Lab until field media are being analyzed.
