Methods to quantify particle air pollution removal by urban vegetation: A review / I. Vigevani, D. Corsini, S. Comin, A. Fini, F. Ferrini. - In: ATMOSPHERIC ENVIRONMENT. X. - ISSN 2590-1621. - 21:(2024), pp. 100233.1-100233.25. [10.1016/j.aeaoa.2023.100233]
Abstract:
Among the ecosystem services provided by urban forests, the air quality amelioration is particularly relevant.
The high level of air pollution in modern cities and the indirect involvement of particulate matter (PM) in the
spread of COVID-19 have exacerbated the air quality issue worldwide. However, in the estimation of urban
vegetation effectiveness in particle air pollution removal, there is a lack of a standard procedure. Different
methods are used for this purpose, making the comparison across different studies difficult. Therefore, there is a
need of an extensive review, aimed at: i) identifying the existing direct methods to quantify this ecosystem
service, ii) assessing their pros and cons, accuracy and reliability, sustainability, and iii) laying the foundations to
create a standard method, commonly and universally recognized. We identified and meticulously assessed five
main direct metrics: the gravimetric method (G, 40%), aerosol monitor (AM, 20.5%), wind tunnels and depo-
sition chambers (WT&CH, 19.5%), Scanning Electron Microscopy (SEM, 14%) and Saturation Isothermal
Remanent Magnetization (SIRM, 6%). This work provides a crystal picture and a critical framework of the last
thirty years literature on this topic and lays the foundations to create a common and shareable approach to
quantify the air PM mitigation potential of the urban vegetation. This will be useful to guide researchers and
urban planners in shaping greener, healthier, and more sustainable cities.
