Description
Summary:Several studies found associations between exposure to airborne fungi and allergy, infection, or irritation. This study aimed to characterize airborne fungi populations present in public primary schools in Porto, Portugal, during winter through quantification and identification procedures. Fungal concentration levels and identification were obtained in a total of 73 classrooms. The AirIdeal portable air sampler was used in combination with chloramphenicol malt extract agar. Results showed a wide range of indoor fungi levels, with indoor concentrations higher than outdoors. The most prevalent fungi found indoors were Penicillium sp. (>70%) and Cladosporium sp. As evidence indicates that indoor fungal exposures plays a role in asthma clinical status, these results may contribute to (1) promoting and implementing public health prevention programs and (2) formulating recommendations aimed at providing healthier school environments.
