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.

“…Both ivy and strawberry leaves are considered to be hydrophilic (Walker et al, 2015). Yet, we hypothesize that strawberry leaves are less hydrophilic than ivy leaves (Figures S.2, S.3), which may prevent the deposition of particles (Bakker et al, 1999;Barima et al, 2016). A wind tunnel experiment also showed that the permeability of strawberry leaves, i.e.…”

Atmospheric dust deposition on plants enables the collection of site-specific particulate matter (PM).Knowing the morphology and composition of PM aids in disclosing their emitting sources as well as the associated human health risk. Therefore, this study aimed for a leaf-level holistic analysis of dust accumulation on plant leaves. Plant species (ivy and strawberry) with distinct leaf macro-and micromorphology were exposed during three months at a moderate road traffic site in Antwerp, Belgium.Leaves collected every three weeks were analyzed for their magnetic signature, morphology and elemental content, by a combination of techniques (biomagnetic analyses, ED-XRF, HR-ICP-MS, SEM). Dust accumulation on the leaves was observed both visually (SEM) and magnetically, while the metal enrichment was limited (only evident for Cr) and more variable over time. Temporal dynamics during the second half of the exposure period, due to precipitation events and reduction of atmospheric pollution input, were evidenced in our results (elements/magnetically/SEM). Ivy accumulated more dust than strawberry leaves and seemed less susceptible to wash-off, even though strawberry leaves contain trichomes and a rugged micromorphology, leaf traits considered to be important for capturing PM. The magnetic enrichment (in small-grained, SD/PSD magnetite particles), on the other hand, was not species-specific, indicating a common contributing source.Variations in pollution contributions, meteorological phenomena, leaf traits, particle deposition (and encapsulation) versus micronutrients depletion, are discussed in light of the conducted monitoring campaign. Although not completely elucidative, the complex, multifactorial process of leaf dust accumulation can better be understood through a combination of techniques. Keywords Atmospheric dust deposition • PM leaf accumulation • Biomonitoring • Environmental magnetism • ED-XRF • HR-ICP-MS Highlights• Ivy and strawberry leaves followed up every three weeks for a three months period. • Dust accumulation observed visually and magnetically, yet limited in metal built-up.• Ivy accumulated more than strawberry, with the latter more susceptible to wash-off.• Site-source and precipitation dynamics over time were detected by leaf biomonitoring.• Combination of techniques assists in understanding the complex leaf-dust interaction.

“…El PM, especialmente la fracción fina, a menudo contienen hidrocarburos aromáticos policíclicos, dibenzo-p-dioxinas policloradas y dibenzofuranos, bifenilos policlorados y metales pesados (Barima et al, 2016). Las partículas finas y ultrafinas generalmente se originan en procesos de combustión, como el escape de un motor o incendios forestales, y consisten en compuestos carbonosos y metales de transición como vanadio (V), Ni y Zn.…”

La vegetación actúa como filtro biológico que retiene partículas en su superficie. Brinda un servicio ecosistémico que permite mejorar la calidad del aire, especialmente en zonas urbanas y áreas industriales donde, en ocasiones, el material particulado (PM) excede los límites permisibles. El PM causa afecciones a la salud como enfermedades respiratorias, cardiovasculares e incluso cáncer, por lo que se han buscado alternativas que permitan reducir sus concentraciones en el aire ambiente. La vegetación puede mejorar la calidad del aire, al capturar y retener PM en su superficie. La gran área foliar de los árboles, los convierte en el tipo de vegetación más eficaz para dicho propósito, a su vez, las hojas pequeñas y de formas complejas incrementan la eficacia. Para conocer la capacidad de la vegetación, existen diversos métodos que remueven y cuantifican el PM. En este estudio se evaluó el grado de concordancia entre los métodos de barrido y lavado de hoja. Para ello se estimaron las fracciones grande, gruesa y fina de PM, por ambos métodos, en la superficie foliar de dos especies arbóreas de la misma familia, Salicaceae, pero con características diferentes, Salix humboldtiana y Populus balsamifera. Se tomaron muestras de 10 individuos de cada especie, con su posterior réplica. Se calculó el grado de concordancia usando el coeficiente de correlación y concordancia de Lin (CCC), además del error absoluto. No se encontraron diferencias estadísticamente significativas en las capacidades de acumulación entre especies, resultando un grado de acuerdo pobre entre los métodos (< 0,90), corroborado por valores de error relativo entre el 29,18 % y 195,79 %. De tal modo, el método de barrido de hoja no puede sustituir al de lavado, y, al contrario, como resaltan nuevas investigaciones, estos métodos deben complementarse para asegurar una mayor eficiencia de cuantificación de PM. Palabras claves: Calidad del aire. Material particulado. Lavado de hoja. Barrido de hoja.
