IAQ-related health problems in schools

IAQ can potentially affect the health of students /staff in the educational process

Children are more susceptible to poor IAQ

Students spend 4-8 hrs a day in school

Magnitude of schoolchildren population

IAQ pollutants are 2 to 5 times higher

Protocol for field work Training and consultation The same portable monitors and

passive samplers Blank samples Passive samples were collected by the

countries and analysed by one laboratory

Samples transportation were performed in compliance with the same protocol
