World Meteorological Organization v ACKNOWLEDGEMENTS The authors would like to acknowledge the support and contributions of all project partners, past and present, in providing for the initial set-up and ongoing operation of the Sable Island Air Monitoring Program. [...] The analysis revealed that the majority of the events examined seemed to indicate transboundary flows from onshore areas in Canada and/or the US as the main reason behind the elevated pollutant levels. [...] The focus of the proposal was to provide baseline information on the ambient air quality on Sable Island and to monitor trends in air quality as development of the Nova Scotia offshore oil and gas exploration expanded. [...] Depending on the nature of the particulate, it may also displace oxygen in the blood or enter the blood stream and increase the viscosity of blood, thereby constricting passage through the blood vessels. [...] The existence of the GHG program and the Greenhouse Gas Measurement Lab in Downsview, Ontario, has allowed the Sable Island Air Monitoring Program to take advantage of communications and satellite equipment used to collect and transfer data from the island (see Section 3.5).
