Environmental Toxicology 26/09/16 Organic contamination in tree swallow (Tachycineta bicolor) nestlings at United States and binational great Lakes Areas of Concern. Contaminant exposure of tree swallows, Tachycineta bicolor, nesting in 27 Areas of Concern (AOCs) in the Great Lakes basin was assessed from 2010 to 2014 to assist managers and regulators in their assessments of Great Lakes AOCs.
Contaminant concentrations in nestlings from AOCs were compared with those in nestlings from nearby non-AOC sites. Polychlorinated biphenyl (PCB) and polybrominated diphenyl ether concentrations in tree swallow nestling carcasses at 30% and 33% of AOCs, respectively, were below the mean concentration for non-AOCs. Polycyclic aromatic hydrocarbon (PAH) concentrations in nestling stomach contents and perfluorinated compound concentrations in nestling plasma at 67% and 64% of AOCs, respectively, were below the mean concentration for non-AOCs. Concentrations of PCBs in nestling carcasses were elevated at some AOCs but modest compared with highly PCB-contaminated sites where reproductive effects have been documented. AMERICAN FISHERIES SOCIETY 29/09/16 Widespread Plastic Pollution Found in Great Lakes Tributaries.
Release Date: September 14, 2016 Tiny pieces of harmful plastic, called microplastics, are prevalent in many rivers that flow into the Great Lakes, according to a study published today in the journal Environmental Science & Technology.
Results are also illustrated on a new USGS microplastics website. Microplastics fall off decomposing bottles and bags, wear off of synthetic clothing and are manufactured into some toothpastes and lotions.

Although significant progress over the past 20 years has substantially reduced the discharge of toxic and persistent chemicals to the Great Lakes, persistent high concentrations of contaminants in the bottom sediments of rivers and harbors have raised considerable concern about potential risks to aquatic organisms, wildlife, and humans. LAPRESSE 21/06/15 Au moins 500 toxines menacent les Grands Lacs. Des dizaines de groupes écologistes se préoccupent de la santé des cours d'eau et ils feront part de leurs inquiétudes dans une lettre qui sera envoyée lundi au comité exécutif des Grands Lacs - organisation responsable de surveiller la mise en place de l'accord.
Les militants affirment que peu de progrès ont été accomplis par le sous-comité chargé d'enrayer le problème de la pollution. L'Association canadienne du droit de l'environnement en était venue à la même conclusion dans une nouvelle étude. Selon eux, l'approche «lente» du comité n'est pas en phase avec le problème, qui est urgent et grave, rappellent-ils. Il ne faut pas attendre des années pour agir afin d'éviter que ces produits chimiques se retrouvent dans les cours d'eau ou pour les nettoyer s'il est trop tard, ajoutent-ils. L'Accord relatif à la qualité de l'eau dans les Grands Lacs laisse la responsabilité au sous-comité d'identifier les produits chimiques les plus dangereux.

Is dilution really the solution to pollution—especially when it’s nuclear waste that can stay radioactive for 100,000 years?
A four-member expert group told a federal joint review panel it is. The panel is examining an Ontario Power Generation proposal to bury low- and intermediate-level nuclear waste from the Darlington, Pickering and Bruce nuclear plants in limestone at the Bruce site in Kincardine, beside Lake Huron. According to the Toronto Star, the experts reported that 1,000 cubic meters of contaminated water could leak from the site, although it’s “highly improbable.” But even if it did leak, they argued, the amount is small compared to Lake Huron’s water volume and the quantity of rain that falls into it. Others aren’t convinced.

AP 10/01/15 Scientists concerned about plastic pollution in Great Lakes. John Flesher, The Associated Press Published Saturday, January 10, 2015 8:14AM EST TRAVERSE CITY, Mich. -- Scientists who have reported that the Great Lakes are awash in tiny bits of plastic are raising new alarms about a little-noticed form of the debris turning up in sampling nets: synthetic fibers from garments, cleaning cloths and other consumer products.
They are known as "microfibers" -- exceedingly fine filaments made of petroleum-based materials such as polyester and nylon that are woven together into fabrics. "When we launder our clothes, some of the little microfibers will break off and go down the drain to the wastewater treatment facility and end up in our bodies of water," Sherri "Sam" Mason, a chemist with the State University of New York at Fredonia, said Friday.
The fibers are so minuscule that people typically don't realize their favourite pullover fleece can shed thousands of them with every washing, as the journal Environmental Science & Technology reported in 2011.

À l'heure actuelle, on observe de faibles concentrations de produits chimiques toxiques dans les eaux du large, et une diminution de la concentration de certains produits chimiques existants dans les poissons, comme les biphényles polychlorés et le dichlorodiphényltrichloréthane. Toutefois, toutes les recommandations relatives à la qualité de l'eau ne sont pas respectées.
Malgré la diversité des tendances pour les divers contaminants surveillés, la qualité générale de l'eau a plutôt tendance à se détériorer. Les symptômes de l'enrichissement en éléments nutritifs dans les zones côtières persistent et les tendances à la détérioration des algues empirent dans certaines régions des Grands Lacs.
Les concentrations de phosphore dans les eaux du large deviennent trop faibles dans certains lacs pour accueillir les réseaux alimentaires productifs.

ANN ARBOR—With Earth Day approaching, a new Great Lakes survey by U.S. and Canadian researchers represents one of the largest attempts in recent decades to assess public views on a wide range of issues in the Great Lakes basin.
The survey of more than 1,000 Americans and Canadians in the region revealed: The vast majority of residents believe the lakes are in at least fair condition, but not necessarily improving.Residents expressed the most overall support for policies that directly reduce pollution, including rebuilding sewers and regulating the release of pharmaceuticals.
Great Lakes residents from the U.S. and Canada overwhelmingly prefer the development of wind energy and other renewable sources to hydraulic fracturing, according to the survey conducted by three universities under the Great Lakes Policy Research Network. The findings are presented in three reports: one focusing on environmental issues, another on wind energy, and a third on hydraulic fracturing, or fracking.

Great Lakes aquaculture could become a $1 billion industry in Canada and the U.S., according to a 2014 paper. One key for reaching that potential is for the Great Lakes states to follow Canada and legalize offshore aquaculture, reports the paper that was sponsored by Michigan Sea Grant, NOAA, Michigan State University and the state of Michigan. Offshore aquaculture involves farm-raising up to several million fish in cages along the coasts of natural bodies of water instead of the inland practice of using large landlocked tanks. It is legally done in the ocean on both coasts of the United States. In Canada, the practice has sustained dozens of farms in northern Lake Huron for 15 years.
