“…The intercepted particles can be absorbed into the tree, though most particles that are intercepted are retained on the plant surface. The ability to intercept PM 2.5 varies with tree species 48 , 55 , roughness of leaves 56 , 57 , cilia number on leaves 58 , 59 , pore structure 11 , wax coat 60 , and environmental conditions 16 , 49 . Studies have indicated that PAHs are absorbed together with PM 2.5 absorption 33 , 56 , 61 .…”

This study is aim to illustrate Phyllostachys edulis’ role in affecting air quality under hazy day and solar day. P. edulis is a crucial plants growing well at suburban area at China Southern. In this manuscript, on 2 weather conditions (hazy day; solar day), changes in atmospheric particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), associated volatile organic compounds (VOCs), and PAHs in leaves and soils were measured, with PM-detection equipment and the GC-MC method, in a typical bamboo forest at suburban areas. The results showed that: (1) Bamboo forest decreased atmospheric PM2.5 and PM10 concentrations significantly by 20% and 15%, respectively, on the hazy day nightfall time, when they were times higher than that on any other time. Also, similar effects on atmospheric PAHs and VOCs were found. (2) Significant increases in PAHs of leaves and soil were found inside the forest on the hazy day. (3) Bamboo forest also reduced the atmospheric VOC concentrations, and changed the compounds of 10 VOCs present in the highest concentration list. Thus, bamboo forests strongly regulate atmospheric PM2.5 through capture or retention, for the changes in atmospheric VOCs and increase in PAHs of leaves and soil.

“…Therefore APTI, morphological and socio-economic characteristics of a plant are combined to obtain API (Ogunkunle et al, 2015). API assesses the potential with plants in scavenging pollutants in atmosphere (Gupta et al, 2016). According to the results (Table 4 and Table 5) of this study, suitability of the tree species for urban roadside vegetation varied as M. indica > C. fistula > A. indica = F. benjamina > M. calabura .…”

“…Ascorbic acid is a natural detoxicant of air pollutants (Ogunkunle et al, 2015). As well, it is a scavenging molecule of free radicals that hinder enzymes and a catalyst for various physiological and biochemical processes (Gupta et al, 2016).…”

“…According to (Gupta et al, 2016), stressful conditions are indicated by lowering of total chlorophyll contents in plants. Such a reduction of chlorophyll contents may be due to various reasons such as degradation by oxidation, reduction and bleaching and inhibition in biosynthesis of chlorophyll molecules by the action of various functional groups among pollutants (Rai, 2016).…”

This study aims to recommend plant species for urban landscaping based on a biomonitoring study accompanied by comparison of Air Pollution Tolerance Indices (APTI) and Anticipated Performance Indices (API) of five tree species (Mangifera indica, Muntingia calabura, Cassia fistula, Azadirachta indica, Ficus benjamina) and four ornamental species (Bougainvillea spectabilis, Ixora coccinea, Ervatamia coronaria, Nerium indicum) found in Matara city area, Sri lanka. APTI was determined by combining the four biochemical and physiological parameters Relative water content (RWC), Total chlorophyll content (TChl), Ascorbic acid content (AA) and Leaf extract pH using a pre-defined formula. Each parameter of all the species was compared with that of it for the control site, Wellamadama premises of University of Ruhuna. Results suggested that RWC, TChl and pH were lower, and AA was higher for the city area in comparison to control site. APTI varied in the decreasing orders C. fistula (13.09), A. indica (11.23), M. indica (11.12), F. benjamina (10.68), M. calabura (9.12) for tree species and E. coronaria (10.22), I. coccinea (10.20), N. indicum (8.85), B. spectabilis (8.43) for ornamental species. Based on APTI, M. indica, C. fistula, A. indica were intermediately tolerant and other species were sensitive to air pollution. The calculated API values suggest, M. indica is ‘excellent’, C. fistula is ‘very good’, F. benjamina and A. indica are ‘good’ and M. calabura is ‘moderate’ in their suitability to be planted on urban landscape as tree species. API values of the tested ornamental plant species showed that B. spectabilis, I. coccinea, E. coronaria as ‘moderate’ and N. indicum as ‘poor’ for urban landscaping. The overall results highlight the suitability of APTI and API as simple, inexpensive, and convenient methods for recommending plant species for urban areas with sound automobile pollution.
