The chemicals may become wind-borne when giant excavators dig them up and then deposit them into 400-ton dump trucks.Upgraders at some oil sands projects that separate the oil bitumen from its surrounding sand are believed to emit PAHs.Asked about the study, Adam Sweet, a spokesman for Peter Kent, Canada’s environment minister, emphasized in an e-mail that with the exception of one lake very close to the oil sands, the levels of contaminants measured by the researchers “did not exceed Canadian guidelines and were low compared to urban areas.”He added that an environmental monitoring program for the region announced last February 2012 was put into effect “to address the very concerns raised by such studies” and to “provide an improved understanding of the long-term cumulative effects of oil sands development.”Earlier research has suggested several different ways that the chemicals could spread.Most oil sand production involve large-scale open-pit mining.Bank Track is the international tracking, campaigning and civil society support organisation focused on commercial banks and their finance.We aim to stop banks from financing harmful business activities and promote a banking sector that contributes to just societies and a healthy planet.The shale sector moved fast to innovate and cut costs to survive the oil price crash.In 2014, producing oil from most shale fields cost more than the average a barrel needed for a new Canadian oil sands project to make money.
The development of the technique using steam two decades ago made Canada’s sands the new frontier for the oil industry, and majors were among the firms that flocked to buy in. That failure, energy-industry entrepreneurs and venture capitalists told Reuters, is rooted in a risk-averse culture that has left oil sands years behind U. OL from oil sands has made innovation tougher because there are fewer potential customers who might adopt new technology, said Joe Gasca, chairman of Fractal Systems Inc.
OTTAWA — The development of Alberta’s oil sands has increased levels of cancer-causing compounds in surrounding lakes well beyond natural levels, Canadian researchers reported in a study released on Monday.
And they said the contamination covered a wider area than had previously been believed.
Samples from one test site, the paper said, now show 2.5 to 23 times more PAHs in current sediment than in layers dating back to around 1960.“We’re not saying these are poisonous ponds,” Professor Smol said. It’s not too late but the trend is not looking good.” He said that the wilderness lakes studied by the group were now contaminated as much as lakes in urban centers.
The study is likely to provide further ammunition to critics of the industry, who already contend that oil extracted from Canada’s oil sands poses environmental hazards like toxic sludge ponds, greenhouse gas emissions and the destruction of boreal forests.
