The Northern Contaminants Program (NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DBA.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples. Early studies found a wide variety of substances, many of which had no Arctic or Canadian sources, but which were, nevertheless, reaching unexpectedly high levels in the Arctic ecosystem.


The Canadian Cryospheric Information Network (CCIN) and the Polar Data Catalogue (PDC) have been developed over the past two decades through collaborative partnerships between the University of Waterloo and numerous government, university, and private organizations to provide the data and information management infrastructure for the Canadian cryospheric community. The PDC is one of Canada’s primary online sources for data and information about the Arctic and is Canada's National Antarctica Data Centre.

Analysis of Priority Alkyl Aryl Sulfonates (AAS) in Wastewater 2018

In 2018 samples of raw influent and final effluent wastewater from fourteen municipal wastewater treatment plants at various locations in Canada were analyzed for priority alkyl aryl sulfonates (AAS) using the methods developed by Van Stempvoort and Brown (2018). The analyses included seven homologues of linear alkyl benzenesulfonates (ABS), nine homologues of branched ABS, and six homologues of alkyl-phenoxybenzene-sulfonates (APBS). The latter included five homologues of monoalkyldiphenylether disulfonates (MADS) and one monoalkyldiphenylether sulfonate (MAMS) homologue.

In the samples of raw influent wastewater from the fourteen treatment plants, the concentrations of linear ABS (total) ranged from 349 to 2701 µg/L, the concentrations of branched ABS (total) ranged from 20 to 126 µg/L, and the concentrations of APBS (total) ranged from 0.9 to 13.6 µg/L (Table 7). These are apparently the first published reports of the detections of APBS in wastewater. Generally the samples of final effluent from the same plants had much lower concentrations: the linear ABS ranged from 0.25 to 900 µg/L, the branched ABS ranged from below detection to 58 µg/L, and the APBS ranged from below detection to 4 µg/L. The APBS appeared to be the most resistant to loss during wastewater treatment. The most effective wastewater treatments were those that involved either aeration or advanced treatment including biological nutrient removal. Two treatment plants that had primary treatment only, and were sampled after heavy rains, had the highest AAS concentrations in the final effluent. The relative abundances of both linear ABS and branched ABS homologues in the raw influent wastewater suggest that they are derived primarily from commercial linear ABS products, which contain branched ABS as impurities. During wastewater treatment, the inferred losses (decreases in concentrations) of both linear ABS and branched ABS tended to increase with increasing carbon number.

APBS were detected in all wastewater samples; five homologues of MADS were detected in raw influent wastewater at average concentrations ranging from 0.02 to 3.95 µg/L. Four of the MADS homologues were detectable in final effluent samples at average concentrations ranging from 0.04 to 0.74 µg/L. The MAMS C12 homologue was detected in 59% of the raw influent samples and a few of the final effluent samples. The ratio of the relative abundance of the MADS and MAMS homologues detected in the raw influent was very different than what was measured in the commercial APBS product that was analyzed (Calfax DB-45).

Equipment blanks collected as quality control samples indicated contamination by linear ABS and branched ABS, probably derived from a cleaning agent used to prepare the sample containers. For future analyses of AAS in wastewater, we recommend that sample containers be used that have not been exposed to detergents or other cleaning agents that contain surfactants.

Shoreline mapping vector data in regions along Canada's north coast, based on low-altitude helicopter videography in support of environmental emergency preparedness efforts

With the changing climate conditions, marine traffic along Canada’s coastal regions has increased over the past couple of decades and the need to improve our state of preparedness for oil-spill-related emergencies is critical. Baseline coastal information, such as shoreline form, substrate, and vegetation type, is required for prioritizing operations, coordinating onsite spill response activities (i.e. Shoreline Cleanup Assessment Technique [SCAT]), and providing information for wildlife and ecosystem management.   
  
  Between 2010 and 2016, georeferenced high-definition videography and photos were collected for various study sites along the north coast of Canada. The study areas include Beaufort Sea, Mackenzie Delta channels and Banks Island in the western Canadian Arctic and James Bay, Hudson Bay, Nunavik, Resolute Bay, Victoria Strait, Baffin Island and Coronation Gulf in the eastern Canadian Arctic.  
  
  Data was collected during ice-free and low tide conditions (where applicable) between July and September. Low-altitude helicopter surveys were conducted at each study site to capture video of the shoreline characteristics. In addition to acquiring videography, ground-based observations were recorded in several locations for validation.  
  
  Shoreline segmentation was then carried out by manual interpretation of the oblique videography and the photos aided by ancillary data. This involved splitting and classifying the shoreline vectors based on homogeneity of the upper intertidal zone. Detailed geomorphological information (i.e. shoreline type, substrate, slope, height, accessibility etc.) describing the upper intertidal, lower intertidal, supratidal and backshore zones was extracted from the video and entered into a geospatial database using a customized data collection form. In addition, biological characteristics like biobands, water features, fauna, human use etc. observed along the coast were recorded.  
  
  The data was also validated through ground observations (when available) and a second interpreter QA (quality analysis) was performed on each dataset (excluding Nunavik) to ensure high quality and consistency.   
  
  The final dataset contains segments ranging in length from 150 metres to 2500 metres. In total, from 2010 to 2016, within the 8 study sites, about 16,800 km of shoreline were segmented.

Shoreline mapping vector data in regions along Canada's east coast, based on low-altitude helicopter videography in support of environmental emergency preparedness efforts

With the changing climate conditions, marine traffic along Canada’s coastal regions has increased over the past few decades and the need to improve our state of preparedness for oil-spill-related emergencies is critical. Baseline coastal information, such as shoreline form, substrate, and vegetation type, is required for prioritizing operations, coordinating onsite spill response activities (i.e., Shoreline Cleanup Assessment Technique [SCAT]), and providing information for wildlife and ecosystem management.   
  
  Between 2011 and 2016, georeferenced high-definition videography and photos were collected for various study sites along the east coast. The study areas include Labrador, Bay of Fundy and Chedabucto Bay in Atlantic Canada.  
  
  Data was collected during ice-free and low tide conditions (where applicable) between July and September. Low-altitude helicopter surveys were conducted at each study site to capture video of the shoreline characteristics. In addition to acquiring videography, ground-based observations were recorded in several locations for validation.

Supplemental Information

The Climate Change and Air Pollution (CCAP) program was established in 2016 to identify the severity and extent of adverse impacts of current and future air emissions on aquatic ecosystems to support regulatory actions and policy development. The program includes a number of components, including identifying, monitoring and defining air quality and greenhouse gas (GHG) concerns; improving our understanding of the short- and long-term effects of atmospheric pollutants on the environment; developing a plan to combat climate change; and monitoring and reducing both domestic and transboundary emissions of GHGs. The program is also responsible for identifying and studying emerging issues including multipollutant impacts, major urban sources, and effects of increasing heat on air pollutant formation, among others.


On-going cooperation and support with the Provinces and Territories, international governments and organizations and academia are vital to deliver these priorities to Canadians.
