Flying air-monitoring lab tests emissions in oilsands region

A unique aircraft is in Fort McMurray this month to test the cocktail of pollutants emitted by oilsands facilities.

Shao-Meng Li isexcited talkingabout all the gadgets and gizmos on board the twin-propeller Convair580,a flying research lab.

"The aircraft is ideal because it has enough payload that we can put some sophisticated instruments on board," said Li, a research scientist with Environment and Climate Change Canada.

"And ... it has enough range that it could fly in a time frame that's desirable."

The Convair 580, which belongs to theNational Research Council of Canada,has been modified with 25 air-quality-testing instruments in preparation for a series of flights this summerover oilsandsfacilities in theFort McMurrayarea.

The aircraft is "the most extensively instrumented aircraft in Canada for air quality studies," saidStewartCober, research manager with Environment and Climate Change Canada. It's one of only a few planes in the world that can test particles and gases in the air.

This is the second time Li and his team have studied oilsands emissions from high above.

In 2013 the researchers did similar work and found levels of air pollutants from oilsands mines might be underestimated.

But there were gaps in theresearch and now the team is back to sample a larger area with more moderninstruments on board.

"We have newer technology to measure newer compounds that we weren't able to do in 2013," Li said.

Last time the teamtested forhydrocarbonssuch asmethaneand volatile organic compounds, which can be harmful to human health.

The earlierresearchwas restricted to areas such as mines and tailings ponds north of FortMcMurray.

Now they hope to measure most, if not all, hydrocarbons and over a larger area that includes smaller oil and gas operations south towardsCold Lake.

The data will be used to help understand the impact of emissions on the ecosystem and humansover the long term.

"The biggest impact of the research," Cober said,"is understanding where the plumes go and what the level of exposure is.

"Once we know that,we can understand the impactson the ecosystem and the impacts on human health."

The dataproduced could also prompt regulatory change, validating whether the reporting process has established safe targets for emissionsor whether they need to be tightened.
