A systematic review of indoor air quality in schools settings: Focus on microbiome and their relation to particulate matter and chemical pollutants

Objectives: ), and microorganisms, such as bacteria and fungi, can affect school performance, increase absenteeism, and trigger respiratory problems. This systematic review aimed to analyze the potential correlation between the presence of microorganisms and PM and chemical pollutants in school indoor environments. Study design: A systematic literature review was conducted using the methodology PRISMA and 25 articles were selected. Methods: The current systematic review follow the steps: definition of research objectives; selection of the science databases; definition of keywords; establishment of the inclusion and exclusion criteria, evaluation process and evaluation and management of selected studies. Results: ) remain suspended in the air for longer periods, increasing exposure. Conclusions: Despite the methodological variations among the various studies, the results reinforce the need to create effective interventions to reduce pollutant concentrations to minimize health risks for occupants.
