The emission of pollutants from large sources and whole regions can travel hundreds of kilometres, affecting the air quality in neighbouring jurisdictions and can also lead to chemical transformations which form ozone and acidic precipitation, impacting whole regions and countries. Some of the studies to which we have contributed include:

Noranda Horne Smelter, Quebec

Study of the acid rain and heavy metal impact of the Noranda Horne smelter in Quebec, Ontario and the Maritime Provinces. CEMC set up a monitoring network within Quebec to measure air concentrations of sulphur dioxide, sulphates, and metals such as mercury and precipitation sampling for sulphate, nitrate and acidity. We developed the Trans Lagrangian model for the transport and generation of acidifying pollutants to map out the overall impact on the surrounding environment.

Nanticoke and Lakeview Power Plants, Ontario

Modelling study of the long range transport from the Nanticoke and Lakeview power plants for Ontario Hydro (OPG).

Tar Sands, Alberta and Saskatchewan

Modelling study of the long range transport from the Tar Sands operations on Alberta and Saskatchewan.

Ontario Ministry of Environment, Environment Canada

Development of the Eastern Canada emissions inventory and the meteorological component of the ADOM Eulerian model under contract to the Ontario Ministry of Environment and Environment Canada.

Ontario Ministry of Environment

Development of detailed nitrogen oxides and toxic chemical emission inventories for Ontario Ministry of Environment.

Vale Inco, Sudbury

Evaluation of the impact of the Vale Inco smelter metal emissions on nickel concentrations and depositions in areas surrounding New York City.
