The worldwide increase in urban and industrial areas represents a challenge for urban green management, pollutant mitigation and environmental monitoring. We propose an analysis approach for the spatial and spatial-temporal distribution of pollutants in the environment through dendrochemistry techniques, in order to gauge the value of this discipline in urban ecosystem. The proposed analysis models can be useful to evaluate significant changes in space and time related to economic activities and to describe the "impacts" of adopted strategies, as demonstrated in the case study of the opening or closure of factories, and therefore to describe the cause-effect relation connected with human activities. Trees represent a key factor for urban planning, providing a wide variety of ecosystem services including in-depth environmental monitoring, which is one of the main elements to be included in a high quality urban design. The proposed approach aims at suggesting the dendrochemistry as a novel and feasible tool definable as a cost-saving ecosystem service in the urban context.

“…affects dust deposition. Emphasizing on PM 2.5 being most hazardous [11] due to toxicity [10,11] and fineness, reports indicate conical leaves with 60% DAC compared to expanded leaves of only 47% [8,17]. Broad-leaved, foliar [36] structures such as grooves, glands and trichomes when exposed captured PM 2.5 the most during foliar growth [11,16].…”

“…The capacity of plants to check air pollution is well recognized and cited in the standard literature on numerous occasions [2][3][4][5]. Foliar uptake [5][6][7] of metal and metalloid particulates is reported by many authors [8][9][10][11]. Several studies have attempted on the arrest of air pollutants by avenue plants [6,[12][13][14][15].…”

Mining and related activities cause severe degradation of ambient air quality. A study of particulate matter (PM) across transportation, mining and control (C) sites for dust attenuation capacity (DAC) in selected tree species were carried out in Jharia coalfield (JCF) to estimate the menace of dust pollution and also to measure air pollution tolerance index (APTI). Results indicated that the maximum value of PM 10 and PM 2.5 ranged from 54 to 174 and 29 to 78 μg m − 3 respectively across all the sites. The maximum values occurred in transportation and the minimum at C for both the particulates. Mining and transportation resulted in an increase in PM 10 values by 161 and 200% and PM 2.5 values by 100 and 136% respectively as compared to those in C. The mean concentration of PM 10 and PM 2.5 across the sites exceeded the permissible limit of 100 and 60 μg m − 3 respectively. Transportation was worse than mining due to the high proportion of hazardous fine (PM 2.5) particulates. DAC indicated that Tectona grandis (TG) captured maximum dust (2.15 mg cm − 2) with 85% and Peltophorum inerme (PI) the minimum (0.15 mg cm − 2) with 5% efficiency. The trend for DAC showed TG > Ficus glomerata (FG) > Psidium guajava (PG) > Ficus benghalensis (FB) > Ficus religiosa (FR) > Alstonia scholaris (AS) > Aegle marmelos (AM) > Gmelina arborea (GA) > Dalbergia sissoo (DS) > Syzyzium cumini (SC) > Azadirachta indica (AI) > Terminalia arjuna (TA) > Mangifera indica (MI) > Albizia lebbeck (AL) > PI in descending order. APTI based on pH, total chlorophyll, ascorbic acid and relative water content indicated maximum values for TG (17) with 90% and minimum for PI (10) with 57% of the total and is a measure of the sustainability of plants in JCF. The descending order for APTI was TG > PG > FG > FR > FB > AI > MI > SC > DS > GA > AM > AS > AL > TA > PI. Thus, TG is the most suitable and PI the least. Stomatal density is negatively related to DAC and positively related to APTI. DAC therefore, cannot be attributed to a single factor but a mix of complex factors such as morphological and anatomical characteristics of the leaf, particle size, species type, metabolism, location, meteorology and stress conditions. Based on the findings a greenbelt design was proposed to improve the air quality of the mining and transportation areas.

“…And this varies greatly from tree to tree and plant species [72]. Moreover, rougher leaf surfaces, larger differences in the depths of creases, densely ridged grooves, lower stomatal densities, and more waxes are more conducive for the capture and adsorption of particle matters [73][74][75][76]. In contrast, the leaf surface is smooth, without obvious fluctuation, and there are wide gullies, well-arranged pores, and shallow and sparse grooves, which has relatively weak particle retention and absorption abilities [40].…”

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.
