“…The enzymes responsible for the regeneration and synthesis of carbohydrates and the Calvin cycle, such as ribulose diphosphate carboxylase, fructose diphosphate phosphatase, NADP glyceraldehyde 3-phosphodihydrogenase, phosphoribulokinase, and pseudoheptulose diphosphate phosphatase, are activated by appropriate light intensity, and the reduction in light due to the dust and shade can negatively impact their function and ultimately reduce the concentration of soluble carbohydrates in water 73 .…”

Dust pollution poses environmental hazards, affecting agriculture through reduced sunlight exposure, photosynthesis, crop yields, and food security. Also, dust adversely impacts plant physiology and herbicide efficacy, but our study found it can also enhance certain herbicides. A factorial experiment was conducted in 2019 and replicated in 2020 to evaluate the interactive effects of dust and various herbicide applications, including bentazon, sulfosulfuron, tribenuron-methyl, aminopyralid + florasulam, foramsulfuron + iodosulfuron + thiencarbazone, 2,4-D + MCPA, and acetochlor on redroot pigweed (Amaranthus retroflexus L.) control efficacy. Dust decreased the total chlorophyll 9.2% content of redroot pigweed by 9.2%, while herbicide application reduced the redroot pigweed’s total chlorophyll by 67.5%. The reduction of total chlorophyll content was more pronounced when herbicides were applied in the presence of dust. Herbicides and dust reduced redroot pigweed's leaf, stem weights, and biomass. Finally, the total biomass of plants was reduced by tribenuron-methyl, aminopyralid + florasulam, sulfosulfuron, and foramsulfuron + iodosulfuron + thiencarbazone regardless of dust presence, showing the most significant effect. The study results indicate that herbicides used in the presence of dust could affect redroot pigweed growth, which signifies the presence of dust, resulting in decreased control efficacy or increased rate of herbicide resistance evolution.

“…Evergreen trees collect dust all year round, tree canopies act as a sink of PM, complex tree structures resist wind movement resulting in greater dust deposition on foliage and tree bark could absorb toxic metal containing PM [14,15,[27][28][29]. Herbaceous plants immobilize dust at ground level, especially along roads because traffic is a major source of PM at surface level, limit hazardous dust resuspension from the soil, are feasible for inclusion in most outdoor urban spaces, and are recognized as ruderal species to re-establish vegetation in disturbed habitats [11,13,16,18,19].…”

“…While some plants can be sensitive to air pollution and thus be used as bioindicators, others can adapt, survive and even thrive due to traits including the ones that enable them to accumulate large quantities of dust particles on leaf surfaces that serve as natural air filters [10,11,[13][14][15][16]. Of late, much interest and effort have been dedicated to investigating dust accumulation capacity, tolerance and adaptability of trees and herbaceous plants to abate air pollution in a cost-effective, sustainable and safe way [10,11,[16][17][18][19]. Urban greenery extends these beneficial effects by restoring degraded soils, restricting soil erosion and improving ecosystem services by re-establishing vegetation cover [11,12].…”

Plants provide long-term and sustainable solutions to mitigate particulate matter (PM) pollution in urban environments. We evaluated total, fine, coarse and large particle trapping abilities of an equal number of common trees (Carica papaya, Citrus limon, Moringa oleifera, Ozoroa paniculosa, Peltophorum africanum, Psidium guajava) and herbaceous species (Argemone ochroleuca, Catharanthus roseus, Gomphocarpus fruticosus, Ipomoea batatas, Senna italica, Tribulus terrestris) to identify dust accumulators for Sekhukhuneland, a mining–smelting region of South Africa where desertification is becoming problematic. Scanning electron microscopy techniques were used to count and measure particles and relate leaf surface micromorphology to dust accumulation. Three tree and three herbaceous species showed superior dust collection capacity (G. fruticosus > P. guajava > I. batatas > O. paniculosa > C. roseus > M. oleifera). Variations in accumulation of PM sizes were noted among these six species and between adaxial and abaxial leaf surfaces. Compared with large PM, all plants accumulated more fine and coarse fractions which are respirable and thus hazardous to human health. Leaf surface roughness, epicuticular wax and epidermal glands improved dust accumulation. The six preferred plants may serve as forerunner species to abate PM pollution in Sekhukhuneland and other arid regions facing similar climate change and pollution challenges.
