"Through airflow we create more dispersion around the noise barrier, so those people who are living in close proximity to the noise barrier will not have as high a concentration of pollutants affecting them."

Helping develop air-cleaning sound barrier to reduce pollution

People who live near highways can breathe a little easier, thanks to a new type of sound barrier that can help clean the air.

Air pollution is responsible for 3.7 million deaths each year, according to the World Health Organization. Research shows that air pollution contributes to cardiovascular and respiratory health problems, especially among children and the elderly.

Partnering with a Guelph-based Envision SQ, the University of Guelph is helping to improve air quality in Ontario through the design of the SmogStop Barrier, a roadside wall that removes up to 50 per cent of air pollution. Currently, a SmogStop Barrier is in place along Highway 401 in Toronto, helping to convert harmful toxins, such as nitric oxide, into non-harmful compounds. 

Testing for the barrier was conducted at the Ontario Tech University and Western University.

According to Envision SQ, one kilometre of the barrier can remove 16 tonnes of air pollution a year, which is equal to removing 200,000 cars from that stretch of road.

Research is now underway that would utilize the SmogStop technology to improve air quality for indoor buildings, such as advanced manufacturing facilities.
