“…It has been reported in several studies that PM accumulation increases on the leaf margins (Mitchell et al, 2010) or along the main leaf nerves (Tomašević et al, 2005). Many morphological characteristics, such as surface roughness and presence of trichomes, have been shown to increase the amount of PM on leaves (Bakker et al, 1999;Beckett et al, 2000;Leonard et al, 2016). We speculate that in P. serotina PM was mainly accumulated in denser trichome layer along the midrib, but in P. padus due to structure of leaves, for example numerous hollows and ridges on leaf blade, while these features are not equal in terms of the level of accumulation.…”

“…The amount of PM gathered on leaves depends on the density of the plant, the shape of the leaves and the presence of other morphological structures, such as various types of spines, thorns and hairs (trichomes) on the leaf surface. The accumulation of PM can also be increased by the presence of epicuticular waxes, in which particular matter can be immersed (Jouraeva et al, 2002;Leonard et al, 2016).…”

Particulate matter accumulation -further differences between native Prunus padus and non-native P. serotina Received: 14 April 2017; Accepted: 23 June 2017 Abstract: Particulate matter (PM) is one of the most harmful inhaled pollutants. Where pollutants have been emitted into the atmosphere, the most effective method for cleaning the air is through phytoremediation, whereby plants act as biological filters. PM has a negative impact on plants, but knowledge of PM effects on the photosynthetic apparatus is limited. In European forests, species of the genus Prunus L. play a key role in the composition of the forest understory and urban as well as industrial plantings. Shrubs of the native P. padus L. and closely-related invasive alien P. serotina Ehrh. are particularly widespread. Thus, both are good model species in which to study the impact of PM pollution. The aim of this study was to assess the accumulation of PM in the context of leaf morphology and amount of epicuticular waxes on foliage, and the efficiency of the photosynthetic apparatus of P. padus and P. serotina. The study was conducted under controlled conditions using two variants of dust, cement and roadside PM. In addition, we analyzed the absorption of dust by leaves dividing it into three fractions by size (10−100 µm, 2.5−10 µm and 0.2−2.5 µm). Results showed that both P. padus and P. serotina accumulate PM mostly on the surface of their leaves ( S PM), rather than in the wax layer ( W PM). P. padus accumulated higher amounts of PM than did P. serotina. The higher presence of PM on leaves of P. padus resulted in a reduction of the efficiency of the photosynthetic apparatus, manifested by lower rates of photosynthesis and chlorophyll a fluorescence, coinciding with an increased stomatal resistance. A strong negative correlation was found between the amount of PM accumulation and the efficiency of the photosynthetic apparatus in P. padus, but not in P. serotina. We have concluded that alien P. serotina is more tolerant to the conditions of stress caused by PM pollution than is the native P. padus, which may partly explain its success in the invasion in Europe.

“…Although some findings in trees relate the differences in PM deposition among species with the leaf surface [39,40], such relationship was not found in this study. However, the state-of-the-art shows that smaller leaves have a greater potential for PM capture [41,42]. This effect is known as edge effect, which is greater in smaller leaves due to their high perimeter/surface area ratio [43].…”

Potential of Particle Matter Dry Deposition on Green Roofs and Living Walls Vegetation for Mitigating Urban Atmospheric Pollution in Semiarid Climates

Abstract:In the last two decades, the incorporation of green roofs and living walls in buildings has increased significantly worldwide because of their benefits such as building energy savings, promoting biodiversity, controlling water run-off, mitigating urban heat island effect, improving indoor and urban air quality, and connecting people with nature. However, few studies have quantified the impact of green roofs (GRs) and living walls (LWs) on mitigating air pollution, especially in semiarid climates where airborne particle matter (PM) levels are high. Therefore, the aim of this paper is quantifying the dry deposition of PM 10 and PM 2.5 by several vegetation species commonly used in GRs and LWs in semiarid climates. Five species (Pitosporum tobira, Lavandula angustifolia, Lampranthus spectabillis, Sedum album, and Sedum reflexum) for GRs and four species (Aptenia cordiflora, Erigeron karvinskianus, Sedum palmeri, and Sedum spurium p.) for LWs were tested in an experimental facility-through washing, filtering, and weighing-to quantify the dry deposition of PM 2.5 and PM 10 on vegetation leaves as well as PM captured by the leaf wax. The main result is that a significant amount of PM is deposited on the typical vegetation used in GRs and LWs in semiarid climates. However, large differences in PM dry deposition were found among species, ranging from 0.09 µg/cm 2 ·h −1 to 1.32 µg/cm 2 ·h −1 for PM 2.5 , 0.48 µg/cm 2 ·h −1 to 4.7 µg/cm 2 ·h −1 for PM 10 and 0.41 µg/cm 2 ·h −1 to 25.6 µg/cm 2 ·h −1 for leaf wax. The species that showed the highest potential to capture PM were S. album, S. reflexum, S. palmeri, and L. spectabillis. This study shows this green infrastructures can contribute to mitigate air pollution, thus GRs and LWs have the potential for being included in decontamination plans.

“…This is due to the fact that urban forest ecosystem plays an important role as interface between the atmosphere and forest ecosystems [5]. Hence, trees can improve quality urban life where they act as biological absorbers of pollutants [4], especially removing particulate matter and their associated semi-volatile organic compounds from the atmosphere [6]. The ability of plant species to mitigate these pollutants varies significantly due to differences in their leaf surface characteristics such as epicuticular wax, cuticle, epidermis, stomata and trichomes [7].…”
