HUMAN AND ECOLOGICAL HEALTH IN ASUBPEESCHOSEEWAGONG NETUM ANISHINABEK (GRASSY NARROWS FIRST NATION) report prepared for the ANA-Ontario Mercury Working Group prepared by Patricia Sellers, PhD December 2014 FINAL REPORT “The government is not a very trusted steward of the land. They’ve had a hundred and forty one years, since we signed the Treaty with them, to prove that they are a good steward of the land…they continue to license industry to extract resources from our land with devastating results...it is all broken trust.” Chief Roger Fobister, Sr. Asubpeeschoseewagong Netum Anishinabek Human and Ecological Health in Asubpeeschoseewagong Netum Anishinabek, December 2014 i Correct citation for this document: Sellers, P. 2014. Human and Ecological Health in Asubpeeschoseewagong Netum Anishinabek (Grassy Narrows First Nation). Report prepared for the ANA-Ontario Mercury Working Group. 61 p + appendices. Human and Ecological Health in Asubpeeschoseewagong Netum Anishinabek, December 2014 ii Acknowledgements I would like to thank members of the ANA-Ontario Mercury Working Group for the opportunity to do this work. I have learned much and am better for it—I hope that reciprocity is found in its utility. I would also like to thank the group and its colleagues, who procured, borrowed, found, scanned, retrieved, sent, and submitted files and documents as part of the necessary and first centralization process. I thank Anna Sanford for her vital assistance in this step and in the creation of a digital database. I thank everyone who provided feedback on the interim report. Human and Ecological Health in Asubpeeschoseewagong Netum Anishinabek, December 2014 iii FOREWARD The people of Asubpeeschoseewagong Netum Anishinabek (ANA, also known as Grassy Narrows First Nation) were poisoned by mercury released into the Wabigoon-English River system in the 1960s. The source was the uncontrolled discharge of effluent from a chlor-alkali plant upstream at Dryden, Ontario. Since that time, there have been many, many studies on the effects of this discharge on both the river system and the people. The published work of those studies is contained largely within reports and journal articles that date back to the early 1970s. My task was to review all the available and published work related to human and ecological health with respect to ANA and to provide a synthesis. The bulk of this report is thus two sections: “Human Health Research to Date” and “Ecological Health Research to Date.” I was also asked to identify gaps in the published work and a make a list of recommendations for next steps and/or future studies. The gaps and recommendations are the practical components of this report and, at the request of the ANA-Ontario Mercury Working Group, are presented first. Throughout the report, and where necessary, I drew from outside literature to provide context and to help propel ongoing or revived discussions. Readers should be mindful that this report is a reflection of the relevant information available and in published form, and available at the time of writing. What is not included are a) community-based observations, information, and knowledge that are not published, b) studies that are underway or not yet published c) media publications and d) publications not obtainable within the timeframe of this task. As such readers are encouraged, where possible, to supplement, update, or revise this document with relevant information that s/he has access to.
