“…Nowak et al [17] reported that urban trees remove substantially less PM 2.5 than PM 10 . Moreover, in their study on an urban park, Silli et al [47] reported that vegetation contributed to a greater extent to the abatement of PM 10 (12.84%) than to that of a finer PM fraction (PM 2.5 , 2.56%), confirming reports by Yin et al [57] for urban parks in China. Modeling ecological processes do, however, have certain limitations.…”

Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS) approach was applied to the Metropolitan City (MC) of Rome to assess the seasonal particulate matter (PM 10 ) removal capacity of evergreen (broadleaves and conifers) and deciduous species. Moreover, a monetary evaluation of PM 10 removal was performed on the basis of pollution externalities calculated for Europe. Deciduous broadleaves represent the most abundant tree functional group and also yielded the highest total annual PM 10 deposition values (1769 Mg). By contrast, PM 10 removal efficiency (Mg¨ha´1) was 15%-22% higher in evergreen than in deciduous species. To assess the different removal capacity of the three functional groups in an area with homogeneous environmental conditions, a study case was performed in a peri-urban forest protected natural reserve (Castelporziano Presidential Estate). This study case highlighted the importance of deciduous species in summer and of evergreen communities as regards the annual PM 10 removal balance. The monetary evaluation indicated that the overall PM 10 removal value of the MC of Rome amounted to 161.78 million Euros. Our study lends further support to the crucial role played by nature-based solutions for human well-being in urban areas.

“…A third reason for the observed seasonality may involve vegetation. Plant leaves play an important role in cleaning the air (Mitchell et al, 2010;Yin et al, 2011) and accumulating particles (Sternberg et al, 2010;Popek et al, 2013). North China has a temperate climate, and the leaves of deciduous species fall in the winter.…”

a b s t r a c tAirborne particulate matter presents a serious health threat to human beings, but in China there have until now been few epidemiological studies, especially regarding the impact of ambient fine particulate matter (PM 2.5 ). This study explored first the temporal and spatial characteristics of ambient airborne PM 2.5 in China, 2013. Mortality, respiratory diseases, cardiovascular diseases, and chronic bronchitis were then evaluated as four health endpoints attributed to PM 2.5 . The results showed that the average annual were the least polluted months. The most highly polluted areas were concentrated in North China. In terms of the health endpoints attributable to PM 2.5 , there were 763,595 mortality, 149,754 cardiovascular diseases, 446,035 respiratory diseases, and 2,389,035 chronic bronchitis cases. Results were very important to clarify the current PM 2.5 pollution situation and the health impact of PM 2.5 in China. And also provided a reference for the assessing damage caused by PM 2.5 pollution.

“…In China, vegetation covering an area of 1639 ha at eight residential areas in Beijing could remove 2170 tons of dust (Zhang et al, 1997), and trees in the city center could remove 772 tons of PM 10 over a year (Yang et al, 2005). Studies from other Chinese cities showed that concentrations of PM decreased by 9.1% near a forest in Shanghai (Yin et al, 2011) and the amount of dust retained by trees was measured as 8600 t yr -1 in an area of 103 km 2 in Zhengzhou (Zhao et al, 2002). A study in Huizhou, Guangdong province found that foliar dust contains appreciable amounts of Cd, Cr, Cu, Pb, Zn, and S as 0.040 t, 1.63 t, 2.70 t, 1.84 t, 5.54 t, and 19.52 t respectively from a study area (Qiu et al, 2009).…”

As the capital of China, Beijing is continuously exposed to high amount of airborne dust, thus it is necessary to find improvement methods. Taking advantage of phytoremediation, an ecological and friendly way to improve air quality, this study investigates the role of urban plant leaves in removing airborne dust and its associated metals by analyzing leaf samples of 32 plant species in autumn. Results showed that leaves could remove dust from 0.510 to 23.0 g m -2 with an overall mean of 7.50 g m -2 on Beijing roadside sites. Some species removed certain metals more efficiently than others.
