Characterization of leaf-level particulate matter for an industrial city using electron microscopy and X-ray microanalysis

Abstract: This study reports application of monitoring and characterization protocol for particulate matter (PM) deposited on tree leaves, using Quercus ilex as a case study species. The study area is located in the industrial city of Terni in central Italy, with high PM concentrations. Four trees were selected as representative of distinct pollution environments based on their proximity to a steel factory and a street. Wash off from leaves onto cellulose filters were characterized using scanning electron microscopy and… Show more

“…The study area is in Terni, one of the most polluted sites in Central Italy (Sgrigna et al, 2016). The city of Terni (42 • 34' N; 12 • 39' E, elevation 130 m a.s.l., 112.000 inhabitants) is placed in a valley surrounded by three mountains.…”

“…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].…”

“…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].…”
