Foreword

This report provides a summary of the progress to date of research and monitoring studies pertaining to contaminants from long-range sources in northern Canada, and related communications, outreach, capacity-building and policy activities that were conducted in 2014-2015 under the auspices of the Northern Contaminants Program (NCP).

The NCP mandate is to work to reduce and, wherever possible, eliminate contaminants in traditionally harvested foods, while providing information that assists informed decision making by individuals and communities in their food use. The projects reported herein cover the broad range of topics that contribute to understanding and addressing northern contaminants issues, as outlined in the NCP strategic plans (e.g., Blueprints), including dietary contaminant exposure, effects of contaminants on the health of people and ecosystems, contaminant levels and trends in the Arctic environment and wildlife and the influence of climate change, and community-based monitoring and research.

These projects were subject to a comprehensive technical, peer and northern social/cultural review process, involving external peer reviewers, technical review teams, regional contaminants committees and the NCP Management Committee. This review process ensures that each project supports the priorities and objectives of the Northern Contaminants Program, as outlined in the NCP blueprints and the annual call for proposals. All peer reviewers, review teams and regional contaminants committees use evaluation criteria to review and rate proposals. Consultation with northern community authorities and/or Indigenous organizations is required for all projects involving field work in the North and/or analyses of samples, as a condition of approval for funding.

Preliminary results of projects funded in the 2014-2015 year are presented here. Submission of a report for this publication ensures program transparency, allows for timely sharing of results, and is a mandatory deliverable for all recipients of NCP project funding. These reports and any future peer- reviewed publications related to these studies will be available through the NCP Publications Database housed at the Arctic Science and Technology Information System (ASTIS) hosted by the Arctic Institute of North America (AINA) at www.aina.ucalgary.ca/ncp. Other project deliverables include submission of data/ data sets/ metadata to the Polar Data Catalogue at www.polardata.ca.

Introduction

The Northern Contaminants Program (NCP) engages Northerners and scientists in researching and monitoring of long-range contaminants in the Canadian Arctic, that is, contaminants that are transported to the Arctic through atmospheric and oceanic processes from other parts of the world and which remain in the Arctic environment and build up in the food chain. The data generated by the NCP is used to assess ecosystem and human health, and the findings of these assessments are used to address the safety and security of traditional country foods that are important to the health and traditional lifestyles of Northerners and northern communities. The findings also inform policy, resulting in action to eliminate contaminants from long-range sources.

The NCP contributes scientific data and expertise to contaminants-related international initiatives such as the Arctic Monitoring and Assessment Programme (AMAP), and to international agreements such as the UNEP Minamata Convention on Mercury, the Stockholm Convention on Persistent Organic Pollutants, and two protocols under the United Nation Economic Commission for Europe Convention on Long-range Transboundary Air Pollution, working globally to improve the health of Arctic people and wildlife over the long term.

The NCP is directed by a management committee that is chaired by Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC), and consists of representatives from four federal departments (Environment, Fisheries and Oceans, Health and CIRNAC), five territorial, provincial and regional governments (Yukon, Northwest Territories, Nunavut, Nunavik and Nunatsiavut), four northern Aboriginal organizations (Council of Yukon First Nations, Dene Nation, Inuit Tapiriit Kanatami and Inuit Circumpolar Council), five regional contaminants committees, and Canada’s only Arctic-focused Network of Centres of Excellence (ArcticNet).

The management committee is responsible for establishing NCP policy and science priorities and for making final decisions on the allocation of funds. Regional contaminants committees established in Yukon, Northwest Territories, Nunavut, Nunavik and Nunatsiavut support this national committee. Funding for the NCP’s $4.1 million annual budget comes from CIRNAC and Health Canada.

Details about the management structures and review processes used to effectively implement the NCP, and the protocol to be used to publicly disseminate health and harvest information generated by the NCP can be found in the NCP Operational Management Guide (available upon request from the NCP Secretariat).

Highlights of 2014-2015

This report provides a summary of the progress to date of research and activities funded by the Northern Contaminants Program in 2014-2015. It is a compilation of reports submitted by project teams, emphasizing the results of research and related activities that took place during the year.

Some of the program’s highlights for 2014-2015 included:

  • The publication Contaminants in Canada’s North: Summary for Policy Makers (http://pubs.aina.ucalgary.ca/ncp/CACARIIISummary.pdf) was released in April 2015. It summarizes the integrated highlights and main findings from the recent technical assessments on mercury, persistent organic pollutants and health under the NCP. It also presents the NCP’s strategic directions and proposes a series of recommendations for broader measures related to achieving the NCP’s mandate and supporting Arctic science in general (see “10 Key Findings” and “NCP Future Directions” below).
  • Significant contributions by NCP scientists, Indigenous partners and the NCP Secretariat to the circumpolar Arctic Monitoring and Assessment Programme (AMAP) Working Group, as co-authors and co-chairs of scientific expert groups working on updates to circumpolar assessment reports, and as Canada’s Head of Delegation and Vice-Chair to AMAP, during Canada’s chairmanship of the Arctic Council (2013-2015).
  • A successful pilot project on human biomonitoring for contaminants got under way in the Deh Cho Region of the Northwest Territories, where fish consumption advisories have been put in place in recent years.
  • The Community-Based Monitoring subprogram expanded for the first time into all northern regions from Yukon to Nunatsiavut.
  • Finally, long-time Director of the Northern Contaminants Program, Chair of the NCP Management Committee, Russel Shearer, retired from the public service in 2015. He will be missed by the whole NCP community.

10 Key Findings of the Northern Contaminants Program

(from Contaminants in Canada’s North: Summary for Policy Makers)

  1. Concentrations of ‘legacy POPs’ are generally going down across the Arctic.
  2. As ‘new POPs’ come under regulation, their levels in the Arctic decline.
  3. Mercury levels in the Arctic are stabilizing but are still several times higher than during pre-industrial times.
  4. Climate change can affect how POPs and mercury cycle in the Arctic environment and accumulate in wildlife.
  5. The complex movement of contaminants in the Arctic environment and wildlife is now better understood.
  6. Current levels of POPs and mercury may be a risk for the health of some Arctic wildlife species.
  7. While exposure to most POPs and mercury is generally decreasing among Northerners, mercury remains a concern in some regions.
  8. Traditional/country foods continue to be important for maintaining a healthy diet for Northerners.
  9. Environmental exposure to contaminants in the Arctic has been linked to health effects in people.
  10. Continued international action is vital to reducing contaminant levels in the Arctic.

Future Directions of the Northern Contaminants Program: 

(adapted from Contaminants in Canada’s North: Summary for Policy Makers)

In terms of Environmental Monitoring and Research, the NCP will

  • continue to play a critical role in the detection of new chemical contaminants of concern to the Arctic and continuously review and refine its list of contaminants of concern.
  • enhance the measurement of long-term trends of mercury and POPs by filling gaps in geographic coverage.
  • carry out more research to understand the effects of climate change and predict their impacts on contaminant dynamics and ecosystem and human health risks.
  • expand community-based monitoring that builds scientific capacity in the North, and optimizes the use of traditional knowledge.

In terms of Human Health Research, Monitoring and Risk Assessment, the NCP will

  • address ongoing public health concerns related to contaminants and food safety, in partnership with territorial/regional health authorities by:
    • weighing the risks associated with exposure to POPs and mercury against the wide ranging benefits of consuming traditional/country foods, and
    • expanding monitoring of contaminant exposure among human populations across the North, and research on potential health effects in collaboration with Northern communities, to provide current information to public health officials

In terms of Communications and Outreach, the NCP will

  • communicate research results and information about contaminants and risk to Northerners in the context of broader environmental (e.g. climate change) and health messages. Timely and culturally sensitive messages will be developed and communicated in association with regional health authorities and other appropriate spokespeople; these communication initiatives will be evaluated for their effectiveness.
  • ensure that NCP data and information is effectively communicated to key international networks, such as AMAP, and the Global Monitoring Plans under the Stockholm and Minamata Conventions for the purpose of evaluating the effectiveness of global regulations.
