A study was made on indoor air pollution in school rooms and their effect on students, who were living in limited areas, and were exposed to air pollutants in TOKYO. The actual concentrations of pollutants in school rooms were measured, and the p ersonal exposure were monitored. The results were as follows:<BR>1) The indoor and ourdoor concentrations of NO<SUB>2</SUB> had a high correlation. The level of outdoor NO<SUB>2</SUB> was very high, but had a similar pattern with that of indoor NO.<BR>2) Both NO<SUB>2</SUB> and HCHO concentrations at inside of school rooms and outside were measured by TEA (Triethanolamine) and the FILTER BADGE methods both at fixed locations and by mobile persons and it was established that both methods were very accurate.<BR>3) Students personal exposure levels were same in urban and rural areas.<BR>4) Even though the indoor, NO<SUB>2</SUB> levels were less than the Ambient Air Quality Standard, very high NO<SUB>2</SUB>exposure levels were recorded by some students. It is thought that the reason is the students were exposed to high NO<SUB>2</SUB> at homes and on their way to school.<BR>5) HCHO levels in schools were not so high as in residential areas, since schools have less sources of HCHO. Furthermore, the indoor HCHO levels were higher due to indoorsources of HCHO.
