  2. OBJECTIVES • Identify the exposure level in combination with building characteristics and occupant behaviour and activities • Analyse the passive samples • Compare the air quality data measured by the participating centres • Evaluation of the relationship between measured concentrations and possible emission sources • Draw the conclusions

  3. Whystudyindoor air in SCHOOLS ? • 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

  4. Sourcesof Indoor Air Pollution • Within the school building • Polluted outdoor air (traffic, industry)

  5. CHARACTERISTICINDOORSOURCESIN HUNGARIAN SCHOOLS HCHO BTEX 1 • panelling • fabric • plywood • floor carpet • furniture • board • plasticflooring • oilpaint • furniture 7 2 6 8 5 3 4

  8. SAMPLING SITES

  9. SAMPLING PLACES INDOOR  classroom, inthebreathingzone OUTDOOR ambient air, closesttothewindow of theclassroom

  10. SAMPLING PERIOD

  11. SAMPLING DURATION dependingtype of thepollutantsmeasured CO2, CO, PM10, T, RH  schooltime, oneday/classsroom NO2, BTEX, HCHO  3-5 daysdependingonthe Nr of classrooms

  12. INDOOR AIR QUALITY PARAMETERS • CHEMICAL CO2, CO, NO2, BTEX, HCHO, PM10 • PHYSICAL T, RH

  13. SAMPLING METHODS • REAL-TIME MONITORING • T, RH, CO2, CO • PM • INTEGRATED (PASSIVE) SAMPLING • NO2 • BTEX, H2CO

  14. QUALITY ASSURANCE • Protocolforfieldwork • Training and consultation • The sameportablemonitors and passivesamplers • Blanksamples • Passivesampleswerecollectedbythecountries and analysedbyonelaboratory • Samplestransportationwereperformedincompliancewiththesameprotocol
