“…There is a significant relationship between the PAH concentration of the phyllosphere and the PAH degrading fungal population in the phyllosphere. Further, these outcomes exposed that the stress condition created through the deposited PAHs increases the PAH degrading fungal population density in the phyllosphere (Franzetti et al., 2020; Tan et al., 2022). The findings of Chun., 2011, also discovered that the atmospheric PAH concentrations are correlated with the accumulation of PAHs on plant leaves.…”

A variety of anthropogenic sources release hazardous polyaromatic hydrocarbons (PAHs) into the phyllosphere which is an excellent niche for diverse fungi, and some of them have PAHs degradation capabilities. Therefore, this research attempted to determine the PAHs (phenanthrene, anthracene, naphthalene, and pyrene) degradation capability of phyllosphere inhabited Penicillium species. The leaf samples were collected from highly polluted urban areas (Panchikawatta, Pettah, Orugodawatta, Maradana, Sapugaskanda, and Colombo Fort) in Sri Lanka to isolate fungal species inhabiting the phyllosphere. Furthermore, their distribution patterns among the leaf tissue layers were studied using bright-field microscopic observations. Moreover, the best PAH degraders were screened out using plate assays and confirmed through High Performance Liquid Chromatography (HPLC) analysis. Further, their enzymatic activities during the PAHs degradation were analyzed. As per the microscopic observations, the highest fungal distribution was in the upper epidermis of the leaves followed by the fungal distribution in the interspaces of palisade mesophyll layers. Out of isolated fungal species, two Penicillium spp. (Penicillium citrinum P 23 B-91 and Penicillium griseofulvum P 9 B -30) showed the highest PAHs (phenanthrene, anthracene, naphthalene, and pyrene) degradation capabilities. Manganese peroxidase (MnP) enzyme dominated phenanthrene degradation in P. griseofulvum P 9 B -30, which showed the highest phenanthrene degradation ability (61%). In addition, P. citrinum P23B-91 was good at degrading anthracene (88%) and also displayed a higher MnP activity during the anthracene degradation than laccase and lignin peroxidase activities. The discoveries from the toxicity assay during the PAHs degradation processes revealed that the produced byproducts had no toxic effects on the fungal growth cycle and the phyllosphere. Therefore this phyllosphere Penicillium spp. are ideal for the bioremediation of polluted air in urbanized areas.

“…Neighborhood gardens, serving as significant habitats for both indoor and outdoor microorganisms, constitute the primary origin of human exposure to microbes [ [4] , [5] , [6] ]. Phyllosphere microorganisms play critical roles in multiple ecological functions, including plant growth and fitness, and can also affect human respiratory health [ [7] , [8] , [9] ]. However, the health associations of phyllosphere microbial communities (PMCs) in neighborhood gardens and factors that may affect these microbial communities are largely uncharacterized.…”

“…However, it is still largely unclear how urbanization (e.g., the garden age) affects PMCs, especially the human health-associated microbiota. As PMCs can be influenced by pollutants [ 9 , 20 ] and human activities [ 21 ], it is reasonable to presume that PMCs differ in neighborhood gardens between urban and rural areas. Different land-use types selectively affect microbial enrichment [ [22] , [23] , [24] , [25] , [26] ].…”

“…Recently, the indirect way of atmospheric pollutants leading to human health risks through simulating health-related microorganisms has been widely discovered. 89,97,98 AMPs could accelerate the transmission of pathogens and antibiotic resistance genes in indoor air. 29 Our results confirmed the size of ambient AMPs with environmentally realistic abundance was significantly correlated with the relative abundance of pathogenic gene families in the airborne bacterial community.…”

Microplastics are found in various human tissues and are considered harmful, raising concerns about human exposure to microplastics in the environment. Existing research has analyzed indoor and occupational scenarios, but long-term monitoring of ambient atmospheric microplastics (AMPs), especially in highly polluted urban regions, needs to be further investigated. This study estimated human environmental exposure to AMPs by considering inhalation, dust ingestion, and dermal exposure in three urban functional zones within a megacity. The annual exposure quantity was 7.37 × 10 4 items for children and 1.06 × 10 5 items for adults, comparable with the human microplastic consumption from food and water. Significant spatiotemporal differences were observed in the characteristics of AMPs that humans were exposed to, with wind speed and rainfall frequency mainly driving these changes. The annual human AMP exposure quantity in urban green land spaces, which were recognized as relatively low polluted zones, was comparable with that in public service zones and residential zones. Notably, significant positive correlations between the AMP characteristics and the pathogenicity of the airborne bacterial community were discovered. AMP size and immune-mediated disease risks brought by atmospheric microbes showed the most significant relationship, where Sphingomonas might act as the potential key mediator.
