Human exposure to mercury as a consequence of landscape management and socio-economical behaviors. Part II: Four case studies in Canada
The COMERN project was launched in 2001 with the mandate to address the urgent need for the development of a framework enabling researchers, political stakeholders, and communities concerned by the mercury question to evolve towards an interdisciplinary association capable of synergistically combining our knowledge on Hg into an original synthesis and increase our potential for accurate risk communication on specific regional Hg situations. We are presently working at developing a simple index representative of the specific vulnerability of an ecosystem to Hg bioaccumulation and subsequent transfer to humans. This index includes two concepts: (1) the sensitivity to bioaccumulation, induced and influenced by factors such as the Hg loading, the different transport and methylation processes, and human activities and (2) the adaptability of the ecosystem, an evaluation of its resilience, or its capacity to recover and/or to cope with the contamination, taking into account the social and political resources within the communities impacted. We started to apply this approach to four distinct case studies representative of the large spectrums of both Hg contamination and Hg exposure through fish consumption in Canada, i. e. sports fishers of lakes of the boreal forest, commercial fishers of the industrialized region of Lake St Pierre (LSP), Innu nation communities in Labrador and seafood consumers of the Bay of Fundy.
