Port Settlement Fog and Air Quality Study in Iqaluit (149432)
Proposal Status: Conformity Determination Issued
Project Overview
Type of application: New
Proponent name: Rachel Chang
Company: Dalhousie University
Start Date: 2021-07-01
End Date: 2021-09-30
Operation Type: Seasonal
Project Description:
Port settlements have unique atmospheric chemistry due to the confluence of human emissions and natural marine sources such as marine biological activity and sea spray. Port settlements are also often frequently influenced by low visibility events due to fog advected from nearby bodies of water. This project aims to study the chemistry of the atmosphere in Iqaluit by measuring gases and properties of the particulate matter, as well as the relationship between visibility during any observed fog events and the properties of the particles. Measurements will be conducted at the existing Iqaluit meteorological supersite that is part of the Canadian Arctic Weather Science project conducted by Environment and Climate Change Canada at the Iqaluit Airport. We hope to conduct our study for approximately 30 days in the window of July to September 2021, but this will depend on when (if at all) travel restrictions are lifted due to COVID-19. Although 8 people will be involved in the set up of the equipment in the first week, it is anticipated that only 4 will remain for the entire study.

Environmental Impacts
A 10'x6' trailer filled with equipment will be added to the existing Iqaluit Meteorological Supersite. Additional equipment will be set up outside the trailer. All equipment will be sampling ambient outdoor air, either passively by collecting absorption spectra directly, or actively by sucking air through an instrument and then exhausting it back into the atmosphere without any alterations or cleaner, with particulate matter removed. With the exception of one system which uses butanol as a solvent, there are no environmental impacts anticipated due to the direct use of the sampling equipment except for additional noise. Since the proposed site is next to the airport runway, the added noise would be negligible. To mitigate the environmental impact of the butanol instrument, the output will be passed through an activated charcoal scrubber before being exhausted back into the air. The environmental impact of additional temporary structures at the site is negligible when compared to the infrastructure already present.
