Reducing the sources of PM can improve urban air quality and lower the threat to human health, but phytoremediation is believed to be an additional and helpful measure that can be used to alleviate the air pollution by filtering and absorbing some PM through forest crown/leaves
In USA, urban vegetation could remove about 21.49 × 104 t of PM annually [8]. In the Greater London Authority, urban trees with a cover of 20% were estimated to remove 852–2121 t of PM10 (particulate matter with aerodynamic diameter
