“…The characteristics of the ambient particulate and plant leaf form an important criterion of DAC evaluation [29]. These include both solid and liquid such as mist, soot, dust, salt particles, spores, microbes which are very minute (< 10 μm) and forms a significant part [8] of airborne dust. Their morphology and chemical properties depend on their origin.…”

“…Their morphology and chemical properties depend on their origin. They consist of secondary aerosol (gas to particle), combustion products and settled metal and organic vapors [8]. These tiny particulates interact with polycyclic aromatic hydrocarbons, toxic metals, persistent free radicals to form tertiary aerosols.…”

“…Thus, their time effects are varied and site-specific. The entry point of an air pollutant is the leaf cuticle and stomata [8,9]. Further reactions within the plant cell are interrelated depending on particle properties, plant metabolism and external environment.…”

“…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.
