Invisible pollution: Spotlight on clean air coming to Charlotte

It’s all around us, but we usually can’t smell or see air pollution. A major art piece and a series of events coming to Charlotte this spring could help change that.

“Most air pollution in North Carolina is invisible,” said June Blotnick, executive director of Charlotte-based Clean Air Carolina. The group is bringing “Particle Falls” back to Charlotte, starting Feb. 28.

The art installation will run through Mar. 28, projected on the side of UNC Charlotte’s Center City building. Particle Falls is a display that’s updated in real time with data from air sensors. So, if a diesel truck goes by, you’ll see the color and pattern change to indicate higher pollution levels — a reminder of the pollution that’s there even when you don’t notice.

That’s one of the biggest issues air advocates face in Charlotte, Blotnick said. Many of the region’s other environmental problems are easier to see or feel: A shrinking tree canopy, mud and trash clogging streams, relentless summers of record heat.

“That’s always been the challenge. You can’t see it,” said Blotnick. 

In some ways, that’s a good problem to have. The region’s air quality has improved markedly since the mid-2000s, when she was hired at Clean Air Carolina. That’s largely the result of better pollution controls at coal-fired power plants, as well as more efficient cars and other light vehicles.

For perspective, Mecklenburg County saw 242 days of “green,” or good, air quality in 2018. That’s more than double the number of good-quality air days in the mid-2000s, when Mecklenburg routinely saw barely over 100 green days and the majority of the year was spent with air measured at “moderate” or unhealthy levels of pollution.

But Mecklenburg is at the borderline for meeting federal ozone concentration standards.

“We’re still right on the line. That’s not a good thing,” said Blotnick. “And the standard still is not strong enough.”

As overall air quality improves, Clean Air Carolina has been focusing on environmental justice and the disparate impact of air pollution on individual neighborhoods. For example, the group is using hyperlocal monitoring to track air quality in west Charlotte neighborhoods (which have more large air pollution sources, like industrial sites, and are close to major highways) and the more affluent neighborhoods of Dilworth and Myers Park.

Another series of events this spring will put the focus on air quality:

March 13: Panel on sustainable development featuring Peter Plastrik, co-author of Life After Carbon: The Next Global Transformation of Cities, chief planner and deputy Charlotte city manager Taiwo Jaiyeoba, and others; 6:30-8:30pm UNC Charlotte Center City, main lecture hall.

March 20: Panel on active transportation featuring Shannon Binns, Executive Director of Sustain Charlotte, Terry Lansdell, Executive Director of BikeWalk NC and others; 6:30-8:30pm UNC Charlotte Center City, main lecture hall.

March 27: Panel on environmental justice featuring professor Deb Thomas of the UNC Charlotte Department of Geography and Earth Sciences, along with the UNC Charlotte Department of Public Health Sciences, and the Urban Institute with support from the Chancellor’s Diversity Challenge Fund; 6:30-8:30pm UNC Charlotte Center City, main lecture hall.

April 9: The all-day NC BREATHE Conference returns to Charlotte. Held at UNC Charlotte’s Center City building, this conference will spotlight health and equity, the impacts of pollution and climate change. Find the details and register online here.
