New study shows that oilsands mining and processing are polluting the Athabasca River

31.08.2010
Inorganic elements known to be toxic at low concentrations are being discharged to air and water by oilsands mining and processing according to University of Alberta (U of A) research findings being published this month in one of the world's top scientific journals.

The 13 elements being discharged include mercury, arsenic, lead, cadmium and several other metals known to be toxic at trace levels. The paper will appear in the August 30 edition of the Proceedings of the National Academy of Sciences (PNAS).

The results are not surprising according to corresponding author David Schindler – an internationally acclaimed researcher in the Department of Biological Sciences at the U of A – given the huge amounts of many of the same elements that the industry has reported discharging, according to Environment Canada's National Pollutant Release Inventory.

"Given the large amounts of pollutants released, any monitoring program that cannot detect increases in the environment must be considered as incompetent," says Schindler, referring to the Regional Aquatic Monitoring Program.

"The U of A study was deliberately designed to test claims by industry and Alberta politicians that all contaminants in the river are from natural sources," said Schindler.

This included examining patterns of deposition of pollutants in snow and releases to water both near to, and remote from, industry.

"Rather than pollutants increasing continuously downstream in the river due to natural sources, as government has claimed, concentrations of the majority of toxins were always highest near sites of industrial activity," Schindler says.

He notes however that concentrations of many contaminants remained above background levels right up to the Athabasca Delta. Elevated concentrations were in Lake Athabasca, near Fort Chipewyan.

"The releases are in clear violation of section 36, subsection 3 of the Fisheries Act, which prohibits discharge of toxins in any quantity into fish-bearing waters."

Schindler says much of the debate over the impact of oilsands has been based on a combination of conjecture and propaganda, which has not been peer reviewed or published in recognized scientific publications.

An earlier (December, 2009) paper by the research group documented the release by the oilsands industry of a number of organic carcinogens, similar to those released by the BP spill into the Gulf of Mexico, and the Exxon Valdez into the Gulf of Alaska.

Other members of the research group are: Erin Kelly, Charlene Nielsen and Roseanna Radmanovich (U of A), Peter Hodson (Queens University), Jeffrey Short (Oceana, Alaska).

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
