Research from the Dynamic Environment & Ecosystem Health Research group is routinely featured in regional, national and international media. In addition, Dr. Campbell and her research group members are frequently invited to comment on topics related to mercury and environmental contamination, lake health, fish and food webs. Feel free to contact us if you would like expert insights on key environmental stories.

"
Knowing how to name Atlantic Canadian locations using the two forms of sign language most common in those provinces has become much easier, thanks to a new online tool created by a Halifax environmental science professor."  [Link to CBC article] January 30, 2017. (Also mentioned on the CBC Atlantic Canada evening TV news for January 30th)

"That’s Maritime Sign Language for Yarmouth, one of 120 place names shown in an innovative new project connecting the dots between language and geography around the Atlantic Provinces." [Link to Chronicle Herald article] (Jan 31, 2017)

"If you’re wondering how Saint John, New Brunswick differs from St. John’s, Newfoundland and Labrador in sign language, you can find that out quickly through the new Atlantic Provinces Sign Language Place Names map that’s been released by Saint Mary’s University."  [Link to ESRI Canada article] (Feb 14, 2017)

"And for the community there's been a lot of interest in this project and we're hoping that, you know, talking with people like yourself now will get the word out and really sharing this important resource that is now available."  News 95.7. The Sheldon Macleod Show. [Link to PDF transcript of radio interview] (

The Science Files: Microfibres & Accessibility in Science

"And it's quite ironic because they make their products from plastic bottles and ironic that they're trying to save plastic by recycling these bottles and then it becomes an issue at the end."

"We really do need to support and welcome diversity into science. We have to be more diverse and have clever people working together and that's really wonderful because everyone will then bring their own perspectives and different ways of solving problems. And then when we bring these people together that then will really improve how we manage things within the world."

Mercury emissions risk fish, health: Mercury contamination is prevalent around the province's gold mines

"Nova Scotia’s eastern positioning puts the province at risk for mercury emissions – and it has nothing to do with how much we produce."

Reported in The Signal (University of King's College Journalism program newspaper). [Link] March 7, 2016

Fur mercury concentrations in little brown bat colonies across Nova Scotia is related to water chemistry

Little brown bats consume high number of insects, including those with aquatic life cycles. Our research using archived bat fur and long-term monitoring data have shown significant relationships for elevated mercury concentrations in little brown bat colonies which are near waterbodies with more acidic pH and more bioavailable mercury. This shows that mercury not only affects living organisms within lakes, it can also affect terrestrial organisms living around those lakes.

Mercury can be low in fish, even from global hotspots

The mercury biomagnification rate in a global mercury hotspot is low, says a new study conducted in China by an international group of researchers. China is a currently a mercury deposition hotspot because it uses more coal, the largest source of mercury pollution to the atmosphere, than any other nation. “Most of what we know about mercury biomagnification is from temperate ecosystems...

Saint Mary’s Professor Puts Mercury on the Map

With its wild cry and its prominent image on the dollar coin, the common loon is iconic to Canada. Yet, mercury contamination may be stressing our loon populations in the east. A new study co-authored by the Saint Mary’s professor indicates significant risk from mercury toxicity---not only to Canada’s iconic waterbird, but also to some varieties of sportfish.

Mercury may biomagnify more effectively in colder latitudes
Global review reveals additional vulnerability of Arctic ecosystems

A new international review of mercury in freshwater and marine food webs helps explain why many top  predators in the Arctic have high mercury concentrations. The review found that the increase in mercury from prey to predators, biomagnification, is greatest at high latitudes, such as the Arctic. [Read more...] Oct 31, 2013.

New National Database Provides Insights on Mercury Levels in Fish Across Canada

The Canadian Fish Mercury Database, assembled to conduct a national assessment of mercury risks to predatory fish and wildlife, was constructed from data collected from measurements of mercury in over 330,000 freshwater fish from more than 5,000 locations across Canada. It provides the most comprehensive summary of fish mercury measurements in Canada. [Read the Environment Canada page...]
