“…The most common microbial group detected in landfills are cellulose degraders, acidogens, acetogens and methanogens (Xu et al 2017 ). Some of the bacteria like Escherichia coli, Proteus mirabilis, Staphylococcus sciurii, Staphylococcus xylosus and fungi like Aspergillus fumigatus, Aspergillus flavus are responsible for the degradation of waste disposed of in landfill (Fraczek and Kozdroj 2016 ). However, these microbes are also associated with various infections in human beings, specifically in the respiratory system (Fraczek and Kozdroj 2016 ; O’Gorman 2011 ).…”

However, these microbes are also associated with various infections in human beings, specifically in the respiratory system (Fraczek and Kozdroj 2016 ; O’Gorman 2011 ). These microbes can be disseminated from landfill sites mainly via three modes–leachate, vector and aerosols (Fedorak and Rogers 1991 ).…”

“…The study also found that concentrations of mesophilic moulds and Aspergillus fumigatus were higher than the bioaerosol concentrations in the local background even at a distance of 200 m and 500 downwind from the property boundary. Fraczek and Kozdroj ( 2016 ) reported that bioaerosols travelled only up to 100–200 m away from landfills. Breza-Boruta ( 2016 ) analysed the bioaerosols of landfill site situated in Northern Poland and reported the presence of fungi species Aspergillus fumigatus, Aspergillus niger, Aspergillus terreus, Cladosporium herbarum and the genus Fusarium .…”

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.

“…The landfill (total area of 37 ha) has been exploited since 1974, and it is the best-organized municipal landfill in Poland. Full description of the studied site and details of air sampling have been given in the article of Frączek and Kozdrój (2016). Briefly, the air samples were collected at 17 sampling points, comprising the active sector (S3), adjacent forest (S4-S9), farmlands (S1, S10, S12, S13, S15-S17) and meadows (S2, S11, S14), located at different distance (104-1187 m) from the reference location (S3).…”

Municipal wastes collected in landfills are a significant source of air contamination and frequently characterize by elevated concentrations of different fungi. Posing a serious health threat to landfill workers and local residents, the fungal aerosol has to be monitored with respect to its quantity and quality. In this study, concentrations of airborne fungi, their particle size distribution, species composition and the presence of cytotoxic strains of Aspergillus fumigatus were assessed in different sites within the landfill area. The quantitative and qualitative changes in the fungal aerosol were determined with respect to a season and landfill activity level (i.e. exploitation or standstill periods). Within the landfill area, particular sites were grouped with regard to airborne fungi concentrations and similarities in species composition. The qualitative analysis indicated that 43 species were shared during both sampling times, and only nine species were characteristic for the standstill period. Among fungal isolates, 21 strains of A. fumigatus revealed cytotoxic activity expressed at different levels, depending on the fungal extract concentrations used in the MTT assay. The results suggested that exposure (especially in summer) to small airborne particles, containing distinct species, may occur not only in the active sector but also in close vicinity to the landfill. Hence, microbial monitoring of the landfill and surrounding area should be carried out taking into account both quantitative aspect supplemented by size distribution analysis and qualitative features, especially of those strains possessing cytotoxic activity.
