“…Moreover, taller trees with larger leaves exhibit enhanced efficiency in absorbing small particles through processes like diffusion, facilitated by turbulent airflow and impaction. Additionally, leaves adorned with trichomes (leaf hairiness) have proven to be significant in capturing and retaining PM [60][61][62]. The deposition of PM is intricately linked to seasons, particularly during spring and summer, when crowded streets experience elevated PM concentrations owing to frequent vehicular stops and accelerations [48,56,63].…”

Air pollution is a pressing environmental concern in urban areas, with particulate matter (PM) posing serious health and environmental threats. Urban greening has emerged as a potential solution to capture and retain PM. This study assesses the PM deposition capacity of five common tree species: Morus alba (M. alba), Ailanthus altissima (A. altissima), Platanus orientalis (P. orientalis), Robinia pseudoacacia (R. pseudoacacia), and Ulmus minor (U. minor) in two highly polluted sites in Tehran, Iran. Additionally, this study investigates the accumulation of heavy metals (Ni, Fe, Cd, and Pb), Organic Carbon (OC), Elemental Carbon (EC), and Total Carbon (TC) on the leaves of these tree species. The results demonstrate species-specific differences in PM deposition capacity, with U. minor and M. alba showing high PM retention. A. altissima exhibits strong capability in adsorbing PM 0.1–2.5, while U. minor demonstrates greater retention of PM > 2.5. Moreover, the deposition of heavy metals varies among species, with R. pseudoacacia and A. altissima capturing higher levels. This study highlights the significance of appropriate tree utilization in urban environments against air pollution in order to make the air healthier in major cities. Awareness of the different tree species capacities leads urban planners and policymakers to make intelligent decisions about urban greening initiatives to improve air quality and overall well-being.

“…Finer dust particles (<2.5 µm in diameter) may act as a desiccant on leaf surfaces, so reducing the drought tolerance of plants (Burkhardt 2010). Deposits of dust can also exacerbate a range of stress factors such as pest infestation, pathogens and drought, and allow phytotoxic heavy metals or gaseous pollutants to enter exposed tissues (Farmer 1993, Soheili et al 2023. In a review of the evidence, Lewis et al (2017) concluded that dust deposition may also significantly reduce the successful reproduction of plants, directly by physically preventing pollination, or indirectly by reducing resources allocated to reproduction through altered physiological processes.…”

Sand and dust storms (SDS) are common in the world’s drylands, regions that are also critically important for global food production. Agriculture is the most prevalent land use resulting in anthropogenic SDS sources, resulting in impacts on cropland and rangeland, but food production is also affected by impacts from natural SDS sources. This review assesses our knowledge of SDS impacts on all the major types of food production in terrestrial and oceanic environments, impacts that occur in all three phases of the wind erosion system: during particle entrainment, during transport, and on deposition. These effects are short term and long term, direct and indirect. Wind erosion is a major cause of land degradation and there is good evidence to indicate that the deleterious effects of SDS can reduce food production via substantially diminished yields of crops, pastures and livestock. However, it is also clear that soil dust plays an important role in major biogeochemical cycles – especially phosphorus, nitrogen and iron – with implications for the valuable environmental services provided by numerous ecosystems, both terrestrial and marine. Ultimately, these nutrients have particular significance for soil formation, ecosystem productivity and food webs on land and at sea, and hence the provision of food for human societies. Efforts to mitigate the negative impacts of SDS on the sustainability of agriculture should be balanced with an appreciation of the significance of soil dust to the Earth system.

“…At present, the PM 2.5 concentration in some cities in China sometimes exceeds 10 µg/m 3 , the annual standard limit recommended by the World Health Organization (WHO) [5], and there is still a long way to go in the prevention and control of atmospheric particulate matter in China. Dust is a kind of particulate matter that naturally settles on the surface under the influence of gravity in the atmospheric environment, and it has a wide range of particle size distribution that varies from <63 µm to >2 mm [6]. Dust is an important medium for the transport of heavy metals, organic matter, and other substances and energy.…”

Regional air quality and major sources can be reflected by dust. 87 dust samples in Nanchang (four residential areas and three roadside points) were collected, with particle size and carbon components determined to discuss the distribution characteristics and the sources. The distribution of dust particle size in different sampling areas was similar, composed mainly of particles larger than 10 μm (over 69.8%). Dust particle size showed a decreasing trend with increasing horizontal distance from the main road and vertical height from the ground. EC in road dust was higher than that in residential dust. EC outdoors was higher than EC indoors in the same area. OC in indoor dust was higher than that in atmospheric dust when there were obvious indoor OC emission sources. The main carbon fractions in residential dust were OC3 and EC1, and in road dust were EC2 and OC3. The distribution of carbon fractions showed that OC3 and EC2 were mainly affected by human activities and motor vehicle emissions, respectively. The ratio of OC/EC and SOC in dust decreased from autumn to winter. SOC in the dust of Nanchang was at a medium level compared to other cities/regions around world. Clustering analysis and principal component analysis indicated that combustion sources (coal and biomass combustion, etc.), motor vehicle exhaust sources (gasoline and diesel vehicles), and human sources (cooking fumes, cigarette smoking, etc.) were the main contributors to the carbon components in dust.
