“Our research shows that climate change is having substantial impacts on Arctic ecosystems, with consequences for exposure to toxic pollutants like mercury,” says co-author Jean-Pierre Desforges, a Postdoctoral Fellow [NRS] at McGill University under the supervision of Nil Basu [NRS/SHN] and Melissa McKinney [NRS].

In the Arctic, climate change and pollution are the biggest threats to top predators like narwhals. Studying the animals’ tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.

The snow may be melting, but it is leaving pollution behind in the form of micro- and nano-plastics according to a McGill study that was recently published in Environmental Pollution. The pollution is largely due to the relatively soluble plastics found in antifreeze products (polyethylene glycols) that can become airborne and picked up by the snow.

Scientists have been looking at pollution affecting the air, land and water around the Athabasca Oil Sands for some time. After looking at contaminants in snow taken from up-to 25 km away from the oil sands, a McGill-led scientific team now suggests that oil sand pollution is also affecting the weather patterns in the surrounding regions.

With spring finally here and warmer temperatures just around the corner, snow will slowly melt away, releasing us from the clutches of winter. However, that’s not the only thing that the melting snow will release. Researchers from McGill University and École de technologie supérieure in Montreal have found that urban snow accumulates a toxic cocktail from car emissions - pollutants that are in turn unleashed into the environment as the weather warms up.

Yevgen Nazarenko (photo), Uday Kurien, Oleg Nepotchatykh and Rodrigo Rangel-Alvarado, with Prof Ariya have published a paper that demonstrates a substantial influence of snow on car exhaust pollution. In particular, the results showed that snow acts as a sink for toxic organic pollutants and nanosized particles from car exhausts. The article is published in Environ. Sci.: Processes Impacts and has attracted much attention, now classified "hot" on the Journal website.
