“…It is worth noting that, referring to Saebø's and Liu's findings, the epicuticular wax played a negative impact on capturing PM [65,66]. Anyway, the results may contribute to urban greening by optimizing living walls [54,67]. Fernández Espinosa showed that leaf roughness was not a main factor when choosing a biomonitor species of airborne particles.…”

The particle matter, particularly the suspended particle matter (PM ≤ 2.5) in the air is not only a risk factor for human health, but also affects the survival and physiological features of plants. Plants show advantages in the adsorption of particle matter, while the factors, such as the leaf shape, leaf distribution density and leaf surface microstructure, such as grooves, folds, stomata, flocculent projections, micro-roughness, long fuzz, short pubescence, wax and secretory products, appeared to play an important role determing their absorption capacity. In this paper, the research progress on the capture or adsorption of atmospheric particles was summarized, and the forest vegetation and woody plants were discuessed. In addition, special attentions were paid to the effect of haze-fog weather on greenhouse plant, the different responses of plant leaves to dust particles and suspended particles, as well as the effect of suspended particles on morphological change of plants. In the future, research should focus on the mechanism of the influence of particulate matter on plants.More advanced effective and convenient research methods like spectral detection method also need to be developed. This paper may provide reference for future studies on plants' response to haze and particle matter.

“…In this environment, we believe the urban railway system is an effective way to ease the traffic pressure. In addition, the tramcar should have played a more important role in perfecting the city environment by getting rid of the power grid and adopting clean renewable energy as its power [8].…”

Performance and economic efficiency of the fuel cell (FC)/battery/super capacitor (SC) hybrid 100% low-floor tramcar is mainly determined by its energy management strategy. In this paper, a train traction model was built to calculate the power output and energy consumption properties of the hybrid tramcar. With the purpose of reducing hydrogen consumption, the genetic algorithm was adopted to optimize the original energy management strategy. The results before and after the optimization show that the power requirement of the tramcar can be satisfied in both situations with the fuel cell (FC) module non-stopped. The maximum output power of the FC is reduced from 170 kW to 101.21 kW. As for the SC, a two-parallel connection module is used instead of the three-parallel one, and the power range changes from −125~250 kW to −67~153 kW. Under the original energy management strategy, the battery cannot be used efficiently with less exporting and absorbent power. Its utilization ratio is improved greatly after optimization. In sum, the equivalent total hydrogen consumption is reduced from 3.3469 kg to 2.8354 kg, dropping by more than 15%.

“…It depends on the particle size and method of land development [1,7]. The number of deposited PMs is affected by: remobilization, amount of wax on leaf surface, climate, environmental factors, weather, leaf size and porosity, micromorphology, and plant height [1,7,[12][13][14]. It has been shown that PM is most efficiently absorbed by broad, rough leaves, with a large number of hairs, although smaller leaves with complex morphology, can also be effective [3,8,14].…”

“…The absorption of PM is negatively influenced by: leaf softness, larger gaps between leaves, or smooth surface. It has been observed that the upper part of the leaf is susceptible to higher gravity sedimentation of larger PMs, where twice as many PM are located as compared to the lower part of the leaf, and PM greater than 10 μm are located only on the upper part of the leaf [4,12].…”

“…However, the influence of the planting structure on air circulation and deposition of pollutants should be taken into account [13,14]. Green walls can cover the vertical planes of walls and buildings [12,15]. There are two types of vertical green systems: a living wall consisting of modular panels attached to the support structure and a second type, which takes advantage of the natural ability of the vines to climb directly onto the elevation or by use of cables and ties.…”

In urban areas, particulate matter (PM) are the leading cause of air pollution. They can adversely affect human health. One of the solutions to reduce pollution and improve air quality is the use of plants as natural, biological filters which trap the particles on the leaves. Studies on the assimilation capacity of species (Hedera helix, Parthenocissus quinquefolia, Fagus sylvatica) were analyzed. In addition, based on two examples of structures in Krakow, the storage capacity of vines such as Hedera helix and Parthenocissus quinquefolia and Fagus sylvatica tree, for fraction of PM (0.2-2.5 μm; 2.5-10 μm; 10-100 μm) was estimated. Analyses have shown the particular efficacy of creeping vines in PM capture.Keywords: air pollution, PM, green walls, phytoremediation, ecology Streszczenie W obszarach miejskich substancje pyłowe są najczęstszą przyczyną zanieczyszczenia powietrza. Cząstki pyłu zawieszonego (PM) mogą szkodliwie oddziaływać na zdrowie człowieka. Jednym z rozwiązań zmniejszających zanieczyszczenie i poprawiających jakość powietrza jest stosowanie roślin jako naturalne, biologiczne filtry, zatrzymujące cząstki stałe na liściach. W artykule przeanalizowano wyniki badań dotyczące zdolności asymilacji pyłów wybranych gatunków: (Hedera helix, Parthenocissus quinquefolia, Fagus sylvatica). Dodatkowo oszacowano zdolność akumulacji pnączy Hedera helix i Parthenocissus quinquefolia oraz drzewa Fagus sylvatica dla frakcji PM (0,2-2,5 μm; 2,5-10 μm; 10-100 μm) na przykładzie dwóch budowli w Krakowie. Analizy wykazały szczególną skuteczność pnączy w wychwytywaniu PM.
