Abstract

Industrial nitrogen (N) emissions in the Athabasca oil sands region (AOSR), Alberta, Canada, affect nitrate (NO3) and ammonium (NH4) deposition rates in close vicinity of industrial emitters. NO3N and NH4N open field and throughfall deposition rates were determined at various sites between 3km and 113km distance to the main oil sand operations between May 2008 and May 2009. NO3 and NH4 were analyzed for δ15NNO3, δ18ONO3, Δ17ONO3 and δ15NNH4. Marked differences in the δ18O and Δ17O values between industrial emissions and background deposition allowed for the estimation of minimum industrial contributions to atmospheric NO3 deposition. δ15NNH4 values also allowed for estimates of industrial contributions to atmospheric NH4 deposition. Results revealed that particularly sites within ∼30km radius from the main oil sands developments are significantly affected by industrial contributions to atmospheric NO3 and NH4 deposition.
