Monitoring of PM10 and PM2.5 particularly in school microenvironments is extremely important due to their impact on children’s health and the global burden of disease. PM10 and PM2.5 concentrations levels were monitored inside and outside 36 natural ventilated classrooms of 12 schools located in Gaza strip, Palestine. The measurements were carried out using hand held particulate matter instrument during fall, winter and spring seasons from October 2011 to May 2012. The average concentration of indoor PM10 was 349.49(±196.57)μg/m3 and for PM2.5 was 103.96(±84.96)μg/m3. Different spatial distribution pattern among and within the schools was observed and the average daily patterns of PM10 and PM2.5 show a clear seasonal variation. For most of the schools a coefficients of divergence (COD) values varied from spatial homogeneity to moderate spatial heterogeneity. However, strong spatial heterogeneity in air pollutant concentrations exists in two schools with higher particle emission. Furthermore, a spatial variation in PM10 and PM2.5 concentration showed in the same building. The concentrations of PM10 and PM2.5 were greater than 1.2 and 1.4 times the concentration in 1st and 2nd floor, respectively. Relatively high COD values at the schools during the three seasons substantiate the need for school-based monitoring program for sensitive populations like school-going children.
