Cyclists will monitor air pollution in Hamilton

Environmentalist Lynda Lukasik wants to give Hamilton cyclists the tools to track air quality along Hamilton streets, bike paths and trails. Information gathered will be used to map the best and worst places to breath in the city.

A local environmental group wants to make scientists out of cyclists this summer with the goal of creating an air pollution map of Hamilton.

Environment Hamilton is hoping to raise at least $6,000 to buy air quality monitors that cyclists can strap to their bicycles. The data they collect riding around the city will be compiled in a map showing Hamilton's air pollution.

Each monitor and GPS system costs about $600. Environment Hamilton hopes to buy 10 of them, and ideally raise another $30,000 or so for someone to administer the program, executive director Lynda Lukasik said. The project has already received $1,200 from Mountain Equipment Co-op.

The technology is small enough to mount on the handlebars of a bicycle. Once mounted, the device will identify the polluton invisible to the naked eye, including how many particles there are, how big the particles are and whether they are attached to any harmful chemicals.

“These compact units will actually measure…the pollution in the air that’s fine enough to get down into your lungs,” she said.

Project to map air quality in Hamilton

The information gathered by multiple monitors will be used to create a map of air quality in Hamilton. Areas with relatively clear air will be shaded green, while those with more particle pollution will be shaded orange or red. The organization Group Against Air Pollution and Smog has created a similar map in Pittsburgh, Penn.

Using the map, cyclists avoid red areas and frequent green areas. But the project is about more than changing behaviours, Lukasik said.

“We really want this to be a productive way to gather information, and if there are areas in the city that are problematic, to bring together the right people to talk about how we solve those problems.”

Data will fill scientific gap

Green represents 2-4% increased risk; Yellow represents 4-6% increased risk; red represents above 6%. The city average for neighourhoods sampled is 4.6%. Image represents 2013 data.

Air quality researcher Dennis Corr said the bicycle project mimics work he’s been doing for years from a specially equipped van. The technology he uses is more sophisticated and more expensive than what Lukasik wants to buy, but Corr says information gathered by the cyclists will be no less valuable.

“Bicycles can travel on bike paths and trails and so on,” Corr said. “I think [the data] will be useful for filling in gaps where we aren’t able to go.”

What excites Corr more than the extra data is the extra scientists the project will produce. Although they don’t have degrees in biology or physics, the cyclists will be playing an active part in research.

“I’ve realized over the years that, no matter how good your science is, if it stays in the basement or lab, it’s no good to anybody,” he said.

Lukasik hopes to have her volunteer scientists out on the street by June. Environment Hamilton is currently applying for community and government grants.
