SCIENTIFIC AMERICAN 01/11/21 Rivers Dump Mercury into Coastal Fisheries. Rivers may carry as much as 1,000 tons of mercury to the world’s coastlines every year, researchers report in Nature Geoscience.

SCIENTIFIC AMERICAN 01/11/21 Rivers Dump Mercury into Coastal Fisheries

This would make rivers the main way this potent neurotoxin reaches coastal oceans, where it most threatens public health. Human mercury exposure is largely linked to coastal fisheries, where the heavy metal accumulates in marine life that we eat. But relatively little of this pollution originates along coastlines; much comes from inland sources such as wildfires, mines and coal-burning power plants. Scientists have long thought this mercury traveled primarily through the atmosphere as vapor or bound to small particles. But the new findings suggest rivers are the greatest pathway for coastal mercury. Yale University biogeochemists Maodian Liu and Peter Raymond worked with colleagues to combine mercury measurements from rivers around the world with data and simulations describing how sediment and biological forms of carbon move through waterways.

BMC PUBLIC HEALTH 06/07/20 Patterns of fish and whale consumption in relation to methylmercury in hair among residents of Western Canadian Arctic communities. Study design This mercury exposure project was an environmental health component of ongoing community-driven projects led by the Canadian North Helicobacter pylori (CANHelp) Working Group in western Canadian Arctic communities (www.canhelpworkinggroup.ca).

BMC PUBLIC HEALTH 06/07/20 Patterns of fish and whale consumption in relation to methylmercury in hair among residents of Western Canadian Arctic communities

The CANHelp Working Group formed during 2006–2008 in response to concerns raised by community leaders about H. pylori infection and gastric cancer risk. This research program is a collaborative effort, linking northern Canadian Indigenous communities, their health care providers and regional health authorities with investigators from multiple disciplines at the University of Alberta [12, 13]. At the invitation of community leaders, cross-sectional projects were established to describe the community health burden from H. pylori infection and associated disease and address community concerns.

ENVIRONNEMENT CANADA 14/09/12 Évaluation nationale des données de la phase 1 du Programme d’étude de suivi des effets sur l’envi. Rapport complet En application de la Loi sur les pêches , le Règlement sur les effluents des mines de métaux de 2002 ( REMM ) oblige les propriétaires ou les exploitants de mines de métaux à réaliser des études de suivi des effets sur l’environnement ( ESEE ) pour évaluer les éventuels effets des effluents de leurs mines.

ENVIRONNEMENT CANADA 14/09/12 Évaluation nationale des données de la phase 1 du Programme d’étude de suivi des effets sur l’envi

Le programme d’ESEE fait avant tout appel à des études de suivi biologique comportant trois volets : une étude des populations de poissons visant à évaluer l’état de santé des poissons, une étude des communautés d’invertébrés benthiques visant à évaluer les effets sur l’habitat des poissons, et le dosage du mercure dans les tissus des poissons pour évaluer les effets sur l’utilisation des ressources halieutiques. Ces études servent à évaluer les effets des effluents des mines de métaux sur l’environnement et à déterminer si les limites réglementaires protègent effectivement l’environnement.

Les faits sur le poisson et le mercure

Les avantages de consommer du poisson au moins deux fois par semaine surpassent grandement les risques. Vous pouvez réduire votre apport en mercure en consommant ces champions santé toutes catégories : poissons gras frais, surgelés ou en conserve, tels que le saumon, la truite arc-en-ciel, l’anchois, la sardine, le maquereau, le hareng et les espèces de thon pâle telles que le listao, le thon à nageoires jaunes et le thon mignon.
