“…The bioaerosols released from the landfill sites commonly comprise bacterial species including Bacillus, Clavibacter, Corynebacterium, Curtobacterium, Micrococcus, Pseudomonas and Staphylococcus , while fungal types include Cladosporium Alternaria , Penicillium and Aspergillus (Abdel Hameed et al 2015 ; Kaarakainen et al 2008 ; Kalwasińska et al 2014 ; Kalwasińska and Burkowska 2013 ; Pagalilauan et al 2018 ; Schlosser et al 2016 ; Vilavert et al 2012 ). The most abundant phyla present in landfill includes Firmicutes followed by Actinobacteria and Proteobacteria (Krishnamurthi and Chakrabarti 2013 ; Xu et al 2017 ).…”

Landfilling is one of the indispensable parts of solid waste management in various countries. Solid waste disposed of in landfill sites provides nutrients for the proliferation of pathogenic microbes which are aerosolized into the atmosphere due to the local meteorology and various waste disposal activities. Bioaerosols released from landfill sites can create health issues for employees and adjoining public. The present study offers an overview of the microbial diversity reported in the air samples collected from various landfill sites worldwide. This paper also discusses other aspects, including effect of meteorological conditions on the bioaerosol concentrations, sampling techniques, bioaerosol exposure and potential health impacts. Analysis of literature concluded that landfill air is dominated by microbial dust or various pathogenic microbes like Enterobacteriaceae , Staphylococcus aureus , Clostridium perfringens , Acinetobacter calcoaceticus and Aspergillus fumigatus . The bioaerosols present in the landfill environment are of respirable sizes and can penetrate deep into lower respiratory systems and trigger respiratory symptoms and chronic pulmonary diseases. Most studies reported higher bioaerosol concentrations in spring and summer as higher temperature and relative humidity provide a favourable environment for survival and multiplication of microbes. Landfill workers involved in solid waste disposal activities are at the highest risk of exposure to these bioaerosols due to their proximity to solid waste and as they practise minimum personal safety and hygiene measures during working hours. Workers are recommended to use personal protective equipment and practise hygiene to reduce the impact of occupational exposure to bioaerosols.

“…Liquid samples may also be appropriately diluted to overcome the overcrowed colonies potentially occurred on agar plates of impactors. Indeed, fungal aerosols in homes, offices, hospitals, animal barns, and waste‐associated facilities have been successfully detected and/or quantified by liquid‐based samplers, namely the BioSampler (SKC Inc, Eighty Four, PA, USA), the all‐glass impinger (AGI‐30, Ace Glass Inc, Vineland, NJ, USA), and the Coriolis sampler (Bertin Technologies, Montigny‐le‐Bretonneux, France) . A variety of fluids have been filled in bioaerosol samplers for fungal collection, including distilled water (DW), phosphate‐buffered saline (PBS), and DW or PBS supplemented with surfactants (eg, Tween‐20, Tween‐80, and Triton X‐100) and antifoam agents …”

This study assessed the collection efficiency (CE) of two popularly used sampling devices (BioSampler and Coriolis sampler) for fungal aerosols. Phosphate‐buffered saline (PBS) supplemented with or without surfactant (Tween‐20, Tween‐80, or Triton X‐100) and antifoam agent was prepared and used as collection liquids. The agar impactor (BioStage) was simultaneously operated with liquid‐based samplers to collect fungi from seven sites located at a university building, public library, and animal farming. Fungal concentrations determined by liquid samplers were divided by those by BioStage, and the ratio values represented CE. Results indicate that the CE of BioSampler was superior to that of Coriolis (P = 0.0001) and the PBS containing surfactant collected fungi better than that without surfactant (P < 0.0001), whereas antifoam agent showed no influence (P = 0.8). Moreover, fungal concentrations determined by BioSampler with surfactant‐added PBS were statistically indifferent from those by BioStage (P > 0.05) with a Spearman correlation coefficient of 0.81‐0.83 (P < 0.01). In addition to sampler and collection liquid, sampling location was also identified as a significant CE factor (P = 0.006), implying potential influences by fungal genera in the studied fields. Overall, BioSampler with surfactant‐supplemented PBS (eg, Triton X‐100) is recommended considering the great CE and compatibility with a variety of analytical assays.

“…It was frequently isolated from soil, paint, textiles food, and other organic matters (Bensch et al., 2012; Ellis, 1977), and also known to be a common endophyte as well as phylloplane fungi (El‐Morsy, 2000; Islam & Hasin, 2000; Levetin & Dorsey, 2006). Cladosporium is often reported in terrestrial atmospheric environments (Abdel Hameed et al., 2015; Burkowska et al., 2011; Frączek et al., 2017; Han et al., 2019; Małecka‐Adamowicz et al., 2017; Wei et al., 2019a, b). These two fungal genera show a strong association with land‐based sources.…”

Fungal Aerosol Diversity Over the Northern South China Sea: The Influence of Land and Ocean

Fungal aerosols are ubiquitous in the atmosphere and can directly and/or indirectly affect the atmospheric cloud formation process, which play an important role in global climate change and human health. In this study, we performed a comprehensive study on airborne fungi over the northern South China Sea (NSCS). Total suspended particle (TSP) samples were collected during a cruise campaign in the NSCS, and fungal community structure was obtained via high‐throughput sequencing method. The abundance of Ascomycota (AMC) was much higher than that of Basidiomycota (BMC) in the marine fungal aerosols over this region. We observed relatively high abundances of Nigrospora and Cladosporium, two genera belonging to AMC, in the near‐coast samples compared to those in the open‐ocean samples. Therefore, we proposed that they could be used as the potential terrestrial source indicators in this region. The richness of fungal diversity and composition of fungal community were found to be dependent on the distance to the Asian continental coast, suggesting the strong influence of terrestrial sources. Over the open ocean, terrestrial and marine contribution could significantly impact the diversity richness and community structure of the fungal aerosols. This study could improve the current understanding of fungal aerosols on their characteristics and influencing factors over the oceanic area.
