“…The leaf samples were collected in the urban area of Nanjing from June to July (Summer) 2023, respectively. The collection of leaf samples was conducted based on previous studies and under the National Atmospheric Deposition Programme (NADP) monitoring initiative protocol [19,20]. Briefly, the leaf samples were taken from 30 species of plants, which are Eucommia ulmoides, Koelreuteria paniculata, Osmanthus fragrans, Buddleja Davidii, Platanus acerifolia, Fatsia japonica, Hedera Helix, Eriobotrya japonica, Cerasus yedoensis, Sapindus mukorossi Gaertn., Hydrangea macrophylla (Thunb.)…”

“…Cai et al [18] documented that the average deposition of PM on leaves was estimated to be 1.71 ± 0.05 g m −2 wk −1 after summarizing 150 studies conducted in 15 countries from 1960 to 2016. Terrestrial trees can considered an effective low-cost, low-energy strategy for removing BC from the atmosphere [19,20]. Some large-scale experiments, including the European Cooperative Air Quality Assessment Network using Bio-indicator Plants and the European Atmospheric Heavy Metal Deposition Survey, have been conducted in European countries to measure the metal and particulate matter deposited on leaves in the air [21,22].…”

“…A study showed that oak trees in Denton, Texas, can accumulate BC ranging from 160 to 299 mg m −2 canopy per year [20]. Previous research has shown that submicron soot particles emitted from traffic emissions and fuel combustions can be captured by the leaves of Platanus acerifolia trees [19]. Furthermore, the adsorption mechanism between carbon black serving as a model compound of soot particles and straight chain alkanes (C 36 H 74 ) as a leaf wax model was studied [23].…”

“…These two methods have been widely used to measure real-time submicron BC in the ambient air worldwide [26]. On the other hand, the leaves of trees are commonly adopted to biomonitor air pollution in areas where measurement sites are scarce [19,27]. However, a method for measuring the BC on tree leaves of bio-monitoring samplers is absent.…”

There is a need for monitoring air pollution associated with black carbon (BC) using a passive monitor is required in remote areas where the measurements are absent. In this pilot study, we developed a quantitative method to determine dry deposition submicron BC using dual-wavelength ultraviolet–visible spectroscopy. Furthermore, we measured the levels of dry deposition BC on plant leaves from 30 plant species located in urban Nanjing using the established method. The oxidative potential of BC on plant leaves as passive bio-monitoring samplers was assessed. The concentrations of black carbon (BC) on tree leaves varied from 0.01 to 1.6 mg m−2. Significant differences in levels of BC across leaves from different tree types were observed. The values of oxidative potential in deposited particles of leaf samples were observed to be in the range of 33–46 nmol min−1 mg−1 using the dithiothreitol (DTT) assay and 18–32 nmol min−1 mg−1 using the ascorbic acid (AA) assay, respectively. In comparison, the oxidative potential of BC-dominated mass in water extracts of leaf samples was in the range of 5–35 nmol min−1 mg−1 measured using the DTT assay and 2 to 12 nmol min−1 mg−1 using the AA assay, respectively. We found variations in the levels of OP across the leaves of different tree types were not large, while the levels of OP in terms of BC-dominated mass varied greatly. These results indicate that the established method with dual-wavelength ultraviolet–visible spectroscopy could provide a simple tool to determine submicron BC in plant leaves of the passive monitor.

“…A review conducted by Cai et al [4] estimated that the mean deposition of PM on leaves was 1.71 ± 0.05 g m −2 •wk −1 after reviewing 150 studies derived from 15 countries. Black carbon aerosols are a major component of ambient PM, and they are released from the incomplete combustion of liquid and solid fuels [5][6][7][8]. Studies have demonstrated that using plants is an environmentally friendly strategy with a low cost to remove black carbon particles in anambient environment [4,7].…”

Biogenic volatile organic compounds (BVOCs) are responsible for the formation of ozone and secondary organic aerosols (SOAs). Our knowledge about how black carbon particles influence BVOC emissions from terrestrial ecosystems is limited; terrestrial vegetation captures black carbon particles as a sink. In this research, the BVOC emissions from the leaves of four terrestrial plants were measured using an RAE PGM-7300 BVOC analyzer. Then, the leaves from four types of trees were exposed to submicron carbon black for 24 h and 48 h in an ambient environment, respectively. Comparisons between the BVOC emissions before and after exposure to submicron carbon black were performed. Our results indicated that the emissions of BVOC from the leaves of four types of trees varied from 90 to 270 μg g−1 h−1 and depended on the species. The exposure to submicron black carbon particles had negligible impacts on the BVOC emissions from the leaves of four types of trees.

Identifying the relationship between the microbiomes of urban dust particles from different biotopes is important because the state of microorganisms can be used to assess the quality of the environment. The aim of this work was to determine the distribution and interaction patterns of microorganisms of dust particles in the air and on leaf surfaces. Metabarcoding of bacterial and fungal communities, PAH, and metal content analyses and electron microscopy were used in this work. The results obtained allowed us to characterise the biological and chemical components of the dust particles. Some bacterial and fungal genera were correlated with benzanthracene, fluoranthene, and Cu, Ni, Co, Zn, and Mn contents. Bacterial communities were found to be more sensitive to all the pollutants studied. PM10 microbial communities circulated between biotopes and study areas due to air flows, as evidenced by the presence of similar ASVs in fungi and bacteria. The results could help to understand the effects of climate change and anthropogenic activities.
