The present study aimed to assess the dispersion of fungal aerosols from municipal solid waste disposal site.</span></span><span style="line-height:115%"><span style="font-family:"Times New Roman","serif""></span></span></span></span></span><br>

Relative humidity and temperature were also measured. Moreover the concentration and type of the fungal taxa isolated from landfill site under different environmental and metrological conditions were evaluated.</span></span></span></span></span></span><br>
<span style="font-size:10pt"><span style="text-autospace:none"><span style="line-height:115%"><span style="font-family:Cambria,"serif""><b><i><span style="line-height:115%"><span style="font-family:"Times New Roman","serif"">Results</span></span></i></b><span style="line-height:115%"><span style="font-family:"Times New Roman","serif"">: The results showed that the maximum and minimum concentrations of fungal aerosol in the landfill site were 256.18 ± 59.7 CFU/m<sup>3</sup> and 76.56 ± 23.2 CFU/m<sup>3</sup>, respectively. The most frequent fungi detected from municipal landfill site included <i>Penicillium</i> (43.67%), <i>Cladosporium</i> (33.54%),<i> Yeast</i> (7.60%), <i>Aspergillus </i>(5.91%), <i>Curvularia</i> (3.62%),<i> Chrysosporium</i> (1.57%), <i>Alternaria</i> (1.54%),<i> Scopulariopsis</i> (0.84%), <i>and Ulocladium </i>(0.60%) taxa. The maximum identified fungal aerosol concentration in the area around the solid waste landfill was 350 CFU/m<sup>3</sup>. Furthermore, the concentration of fungal aerosols in the environment was significantly related to relative humidity, wind direction, and temperature in spring and winter (P < 0.05).</span></span></span></span></span></span><br>
<b><i><span style="font-size:10.0pt"><span style="line-height:115%"><span style="font-family:"Times New Roman","serif"">Conclusion</span></span></span></i></b><span style="font-size:10.0pt"><span style="line-height:115%"><span style="font-family:"Times New Roman","serif"">: Municipal solid waste disposal site can be a potential source for fungal aerosol dispersion. Moreover, fungal aerosols concentration is correlated with wind direction and speed, relative humidity, and temperature.</span></span></span></div>
