“…Some metals are toxic to plants or plants need them at only low concentrations (e.g., As, Cd, Cr, Cu, Ni, Pb, and Zn) [28][29]. Mine tailings, even at 50%, strongly reduced the number of leaves and reduced leaf area.…”

Mining activities generate large amounts of metalrich waste materials and are considered a major cause of soil contamination [1]. In Mexico, mining for gold, silver, and copper started 500 years ago, which has created huge amounts of mine waste, or tailings [2]. These tailings contaminate soil, subsoil, aquifers, surface and ground water, the atmosphere, flora, and fauna. Drinking water is contaminated and animals left to graze accumulate the heavy metals taken up by plants [3-4]. This dispersion of these heavy metals in the environment and their bioaccumulation poses a serious risk to humans [4].

“…LAI of these species is much smaller but still on some species like Achillea millefolium, Berteroa incana, Polygonum aviculare and Brickellia veronicifolia, Flaveri trinervia, and Aster gymnocephalus, much greater amounts of PM are deposited than in other species [57]. In case of Aster gymnocephalus, additionally accumulation of significant amounts of heavy metals was recorded [58].…”

Air pollution presently is a challenge fo-r many areas of the world. Plants are higher organisms that can best deal with this problem despite the fact often in the air is a mixture of pollutants of different origin and toxicity. The world of plants is very diverse and well adopted to changes in the environment, including air. This large biodiversity allowed to select species with a very high tolerance, which are the base for the discipline known as phytoremediation. All plants during their presence in the environment run the process of phytoremediation, but some species tolerate a very high concentration of selected pollutants. Moreover, they are able to uptake/ accumulate and next to degrade/detoxify in order to make them less harmful. Tolerant plant species can be found in very extreme conditions but for phytoremediation are useful plant species which besides being cultivatable, produce a large leaf area and biomass. Urban areas often contribute in creating high polluted sites as street canyons, road crossing, bus stops, and surrounding of heavy traffic freeway. In all these places, air pollution can be mitigated by the presence of selected plant species. Additionally, agronomic practices allow to maintain them on a polluted site and to form them in configuration for optimal deposition of pollutants. Air phytoremediation in urban areas, where at present men spend most of the time, is strongly desired and hard to overestimate if environment and human health and well-being are the prospect.

“…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]. Complex factors were contributing to particle arrest but are significantly plant-specific [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.
