“…The average PM accumulation of broad-leaved trees was less than broad-leaved shrubs. The metaanalysis results showed that PM leaf deposition on shrubs was significantly higher than that of trees (Cai et al 2017).…”

“…The lowest amounts were measured in September. (Cai et al 2017). In this study, monthly data was converted to seasons and showed highest total PM deposited was in spring for trees and shrubs.…”

“…The PM accumulated on the leaf surface were range from 72.31 to 231.84 μg cm -2 . Cai et al (2017) reviewed 150 studies and used a meta-analysis and also found that the weekly PM leaf deposition of conifer species was significantly higher than broad leaves, by approximately 31.9%. These results showed that evergreen conifer species had better performance in accumulating PM both on the leaf surface and in the surface wax, which was accounted for by the structural characteristics and habits of conifer species.…”

“…Different size fractions of airborne PM have different chemical composition and posed adverse effects on human health (Luo et al 2011;Li et al 2017). For example, particulate matters were responsible for respiratory, cardiovascular and others (Cai et al 2017), especially fine particles (Englert et al 2004). To assess the capacity of plant leaves to capture different size fractions, the present study separated quantification of PM into: fine (0.2-2.5 µm), coarse (2.5-10 µm), and large (> 10 µm).…”

Airborne particulate matter (PM) has become a serious environmental problem and harms human health worldwide. Trees can effectively remove particles from the atmosphere and improve the air quality. In this study, a washing and weighing method was used to quantify accumulation of water-soluble ions and insoluble PM on the leaf surfaces and within the wax of the leaves for 17 urban plant species (including 4 shrubs and 13 trees). The deposited PM was determined in three size fractions: fine (0.2-2.5 μm), coarse (2.5-10 μm), and large (> 10 μm). Significant differences in the accumulation of PM were detected among various species. The leaves of Platycladus orientalis and Pinus armandi were the most effective in capturing PM. Across the species, 65 and 35% of PM, on average, deposited on the leaf surface and in the wax, respectively. The greatest PM accumulation by mass on leaves was in the largest PM size fraction, while the accumulation of coarse and fine particle size fractions was smaller. Water-soluble ions accumulated on the leaf surfaces contributed 28% to the total PM mass, on average. This study demonstrated that leaves of woody plants accumulate PM differently, and the most effective plant species should be selected in urban areas for attenuating ambient PM.

“…Continuously exposure to suspended dust particles with larger size will directly cause the formation of leaf dust, which obstructing the respiration of plants. Haze causes low temperatures and high humidity on the ground, which is also a primary cause of various diseases and insect pests such as downy mildew, late blight, and grey mold, etc., leading to crop production, and quality decline [31].…”

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.
