“…Researchers found that the hexatriacontane wax of leaves could interact with ambient black carbon via hydrogen bonding [10]. Our study further explored how black carbon particles can pass through the mechanical barriers in Platanus acerifolia tree leaves, and then eventually relocate into the mesophyll system [7].…”

“…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].…”

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]. For example, a study conducted in Denton, Texas indicated that oak trees can accumulate ambient black carbon amounts ranging from 160 to 299 mg m −2 in a canopy per year [9].…”

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.

“…once a day, and in the high-concentration exposure group, 5 μg L −1 of individual PAHs was sprayed on the leaves once per day. The control group was carried out with the same procedure using de-ionized water on four replicated healthy leaves with similar ages and leaf areas [ 30 ]. During the experiment, the levels of chlorophyll, leaf water content and nitrogen in the leaves were measured using a chlorophyll meter (YT-YC, YunTang Technology, Shandong, China) simultaneously every day [ 31 , 32 ].…”

The leaves of plants can be recommended as a cheap and sustainable environmental protection tool to mitigate PAHs with high toxicity in the ambient environment because they can serve as a reactor to remove ambient PAHs. Although previous studies have demonstrated that PAHs exhibit toxicological features, our knowledge about how ambient PAHs influence the leaves of plants is limited regarding the leaves of plants reducing ambient PAHs as a reactor. In this study, 1-year-old Rosa chinensis Jacq. with good growth potential was selected as a model plant. The leaves of Rosa chinensis Jacq. were exposed to 16 types of PAHs in the environmental concentration exposure group (0.1 μg L−1) and high-concentration exposure group (5 μg L−1) for seven days. In comparison, the leaves of Rosa chinensis Jacq. were exposed to de-ionized water and were chosen as the control group. During the exposure periods, the physiological parameters of leaves including, chlorophyll value, water content, temperature and nitrogen, were monitored using a chlorophyll meter. After 7 days of exposure, the leaves in the control and exposure groups were collected and used for whole-transcriptome analysis. Our results demonstrate that significant differentially expressed genes were observed in the leaves of Rosa chinensis Jacq. exposed to individual PAHs at 5 μg L−1 compared to the control group. These differentially expressed genes were involved in seven main pathways using bioinformatic analyses. In contrast, the levels of PAHs at environmentally relevant concentrations had negligible impacts on the physiological parameters and the gene transcription levels of the leaves of Rosa chinensis Jacq. Our results may provide direct evidence to remove ambient PAHs using terrestrial trees without considering the risk of PAHs at environmentally relevant concentrations on the leaves of terrestrial plants.

“…Although the sensitivity of traditional gas chromatography and electrochemical detection of pesticide residues is high, these methods are expensive and complicated to operate, plus the unknown harm to the human body. Fluorescent carbon quantum dots are being noticed for their excellent biocompatibility, fluorescence stability, and ease of handling (Tao et al 2022a). Methomyl is a carbamate insecticide that is widely used to treat agricultural crops.…”

In the context of the circular economy and decreasing earth resources, waste should be converted into value-added materials such as carbon quantum dots, which are fluorescent nanomaterials with promising applications in sensing, biological imaging, energy storage, and photocatalysis. Here, we review carbon quantum dots with focus on their synthesis from biomass, factors controlling their performance, properties, and applications in energy, medicine, and environmental science. Applications include energy storage in batteries and supercapacitors, renewable energy, pollutant sensing and degradation, drug delivery, biosensing, and bioimaging.
