“…Irrespective of the type of Green Infrastructure (GI) used or the study location, many reports have demonstrated that some species of plant are better than others in capturing PM (Currie and Bass, 2008;Freer-Smith et al, 2005;Leonard et al, 2016;Liang et al, 2017;Saebø et al, 2012;Song et al, 2015; Weerakkody et al, 2017) thus emphasising the need for careful species selection. Evergreen species can be particularly useful in countries where there is seasonal variation, as their foliage is retained throughout A C C E P T E D M A N U S C R I P T the year, and their high PM removal efficiency has been repeatedly reported in previous studies (Beckett et al, 2000;Dochinger, 1980;Hwang et al, 2011;Wang et al 2011).…”

The potential of rainfall to remobilise PM captured on leaves of plants on a living wall and a green screen was studied.  There was a significant impact of rainfall in washing the PM (PM1, PM2.5 and PM10) off the leaves.  There was a differential impact of rainfall in remobilising PM on different species of plants.  A high rainfall intensity had a significant positive impact on PM wash-off from the leaves.

“…Accumulation of particles on surface of leaves depends on physico-chemical nature of the particulates and the characteristics of the contact surface (Bussotti et al 1995; Liang et al 2017). The interaction between plants and the atmosphere occurs mainly via the stomata and therefore can be considered to be an air quality indicator.…”

The aim of this study was to perform a complex assessment of changes in the elements of an ecosystem that are caused by environmental pollution in industrial and urban biotopes. The study focused on three sites: a park, a road and the site of the metallurgical plant “Pokój” in the city of Ruda Śląska (Southern Poland), which are each under a different level of anthropogenic load. Soil and plant material samples ( Plantago major and Plantago lanceolata leaves) were investigated by performing biochemical, ecophysiological and scanning electron microscopy (SEM) analyses. A significant difference was observed in all of the study samples. The content of Pb, Zn and Cd in the soil samples that had been collected at the site of the metallurgical plant exceeded the permitted limits (Cd > 4 mg kg −1 , Pb > 100 mg kg −1 , Zn > 300 mg kg −1 ). The content of Fe, Mn, Pb, Cd and Zn in the plant material was much higher in unwashed samples than in washed samples. The concentrations of potentially toxic elements (PTEs) were below the permitted level in the leaves of Plantago lanceolata for Cd (> 5 mg kg −1 ) and in the leaves of Plantago major for Zn (> 100 mg kg −1 ). The SEM observations revealed a significant decrease in the stomata pore length (SPL) in the Plantago lanceolata leaves that had been collected at the road site compared with the plants from the park site. The elemental content on the leaf surface was also determined using X-ray microanalysis. The total chlorophyll (Chl) content, ascorbic acid (AA), proline, guaiacol peroxidase (GPX) activity, pH, relative water content (RWC) and air pollution tolerance index (APTI) were evaluated. The APTI for the investigated species ranged from 5.6 to 7.4, which demonstrated that the studied plant species are sensitive to air pollutants.

“…2). Most of the selected species are used extensively in urban landscaping in the city of Shanghai (Liang et al 2017). The two-year-old seedlings of the shrub species (six per species) were planted randomly in each plot in April 2015, for a total of 1,440 plants (6 plants × 12 species × 20 plots).…”

In urban areas of China, several plant species are commonly used for ornamental purposes. Many of these plants have demonstrated a good capacity to resist these varied urban stresses, and it would be relevant to verify whether they can be grown on polluted sites and demonstrate some phytoremediation potential. Twelve ornamental shrub species were chosen to be tested for tolerance to inorganic contaminants and capacity to absorb and concentrate heavy metals in their aerial parts. A large split-plot trial comprising 20 plots was set up, and soil was spiked with different metals (Cu, Pb and Zn). In general, all twelve shrub species performed well regardless of the treatment. Two Hibiscus species, H. mutabilis and H. syriacus "Hamabo" were particularly productive. In terms of capacity to uptake metals, two of the best performing species were Spiraea japonica, for copper, and Nandina domestica, for lead. Bioconcentration and transfer factors were low. This could be related to weak development of the root systems in these recently established plants. Species with high yield, such as the two Hibiscus species, presented more interesting values in terms of quantity of metal extracted, and could eventually be recommended for decontamination of soils polluted by inorganics.
