This study aims at understanding the relation between indoor air quality in schools, including both chemical and microbiological determinants, and cognition in children by gathering data across different parts of Europe
The LEARN project, funded by the European Commission, aims to gain an in-depth understanding about indoor air quality in schools and its impact on children's cognitive development. This involves evaluating school cohorts in three different countries (Belgium, Greece and Denmark). In participating schools, we measure and characterise indoor and outdoor air pollutants and evaluate the presence of exposure biomarkers and their effect on children's cognition. Measuring indoor air quality, exposure and creating remedial strategies are crucial steps to improve air quality in the school environment and ensure the well-being of children.

Filtration device will be placed in classrooms. Computational Fluid Dynamics simulations will be used to find optimal position and operation mode for air purification systems in classrooms.
Filtration will be turned off in the control part of the study and then will be turned on during the intervention.

RECRUITINGChange in Correct Detection of continuous Performance Test
Change in the number of times the child responded correctly to the target alphanumeric stimulus. Higher rates of correct detections indicate better attentional capacity.
Time frame: at the end of the intervention and at the end of the sham intervention
Change in the number of correct substitutions of Symbol Digit Modalities Test
Change in the the number of correct substitutions the child performed. Higher number of correct substitutions indicate better information processing ability.
Time frame: at the end of the intervention and at the end of the sham intervention
Change in the Memory Span Task score
Change in the number of longest list of items that a child can repeat back in correct order. Longer list of recalled items indicate better short term memory
Time frame: at the end of the intervention and at the end of the sham intervention
Change in the Signal Detection Test score
Change in the number of correct detection of signals. Higher rates of correct detection indicate better perception ability
Time frame: at the end of the intervention and at the end of the sham intervention
