“…Because plant leaves are directly exposed to the air, air pollution directly changes the physiological characteristics of plant leaves, such as the structure of the epidermis . Some airborne pollutants (e.g., toluene) can be used as carbon sources by some interstate microorganisms, thus changing the structural composition of the community …”

The leaves of plants are colonized by various microorganisms. In comparison to the rhizosphere, less is known about the characteristics and ecological functions of phyllosphere microorganisms. Phyllosphere microorganisms mainly originate from soil, air, and seeds. The composition of phyllosphere microorganisms is mainly affected by ecological and abiotic factors. Phyllosphere microorganisms execute multiple ecological functions by influencing leaf functions and longevity, seed mass, fruit development, and homeostasis of host growth. A plant can respond to phyllosphere microorganisms by secondary metabolite secretion and its immune system. Meanwhile, phyllosphere microorganisms play an important role in ecological stability and environmental safety assessment. However, as a result of the instability of the phyllosphere environment and the poor cultivability of phyllosphere microorganisms in the current research, there are still many limitations, such as the lack of insight into the mechanisms of plant−microorganism interactions, the roles of phyllosphere microorganisms in plant growth processes, the responses of phyllosphere microorganisms to plant metabolites, etc. This review summarizes the latest progress made in the research of the phyllosphere in recent years. This is beneficial for deepening our understanding of phyllosphere microorganisms and promoting the research of plant−atmosphere interactions, plant pathogens, and plant biological control.

“…To evaluate the potential effects of VOCs on the generation of O3 and SOA, the OFPs and SOAFPs were calculated and analyzed in this study. The OFP represents the potential maximum contribution of specific VOC species to O3 generation under the optimal reaction conditions, and is widely used to evaluate the role of VOCs in the formation of O3 (Hanif et al, 2021;Liang et al, 2020;Mitchell et al, 2021). In this study, to identify the OFP of each species of VOCs, the maximum incremental reactivity (MIR) method (Carter, 1994) is used.…”

To understand the characteristics and environmental effects of volatile organic compounds (VOCs) in a typical medium-sized city in China, manual measurements including 56 species of the nonmethane hydrocarbons (NMHCs) were taken at three urban and suburban sites in Huai'an from April to September 2019, and automatic measurements including 106 species of VOCs were taken at the urban center in May and August 2019. Spatial and temporal characteristics of the VOC concentrations were analyzed. Positive matrix factorization (PMF) model was applied to apportion VOC sources. Ozone (O3) formation potentials (OFPs) and secondary organic aerosol (SOA) formation potentials (SOAFPs) were calculated. The results show that the mean VOC concentration was much lower in the urban center than in the suburbs. Generally, proportions of both alkenes and aromatic hydrocarbons were higher and proportion of alkanes was lower in Huai'an than that in big cities, indicating emissions from solvent usage and industrial process play a more important role in the medium-sized city. The results of source apportionment show that solvent usage and industrial process together contributed 53%, and vehicle emission contributed 27% to the ambient VOCs. The dependence of VOC concentrations on temperature indicates that a considerable part of VOCs may come from fugitive emissions. The two-peak pattern of diurnal variation suggests near-surface emissions contributed a lot to the VOCs. Aromatic hydrocarbons were identified as the key component to the formation of O3 and SOA. Furthermore, biogenic emission could contribute greatly (>20%) to the ambient VOCs during daytime in summer, which may have significant effects on O3 formation. Aromatic hydrocarbons were identified as the key component to the formation of O3 and SOA, which should be given more attention in developing air pollution control strategies.

“…Piasecki and Kostyrko [93] developed a method based on a decision matrix that includes six attributes: actual indoor air CO 2 concentration, TVOCs, and formaldehyde concentration, and their anthropogenic and construction product emissions to the indoor environment with a combined weighting scheme for an IAQ index equation. Kim et al [94] suggested an IAQ index which reflects PM 2.5 and CO 2 , divided into five grades from "good" to "hazardous" with a scale of 1 to 100 points, as follows: "good" (0-20); "moderate" (21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40); "unhealthy for a sensitive group" (41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60), "bad" (61-80), and "hazardous" (81)(82)(83)…”

“…Nowadays, as people spend most of their time inside buildings, mainly at home or at the workplace [38], researchers started to change the focus from outdoor air quality (OAQ) [39] to IAQ. According to Hanif et al [40], VOCs are widely recognized to cause significant adverse health effects on humans. Huang et al [41] have concluded that VOCs concentration indoor may become at least ten times higher than outdoor.…”
