iSCAPE researchers have been testing in Dublin how low boundary walls can reduce pedestrian exposure to air pollution. Low boundary wall structures were set up along Pearse Street and measurements were undertaken on the concentrations of the pollutants nitrogen oxides (NOX) and particulate matter at inhalation level in front of and behind the walls.
The results from this experimental work (data was collected in April 2018 and July 2018) demonstrate that a low boundary wall can act as a baffle at street level by altering the natural dispersion pathway, thereby increasing the distance between the pollutant source and pedestrian.
