The indoor air pollution can pose risks to the human health much larger than the air outside because about 90 % of people’s time is spent indoors. This paper aims to study the concentrations of particulate matter (PM10 and MP2.5) within the Federal Institute for Education, Science and Technology of Ceará (Brazil), in Fortaleza campus, aiming to meet the levels at which students and employees are exposed daily to these pollutants. We used the particle counter Aerosol Mass MeOne 831 ® to obtain the data of concentration of particulate matter PM10 and MP2.5 in five environments IFCE : 2 reception rooms ( P1 and P2 ) ; 2 classrooms ( P3 and P5 ) and 1 lab ( P4 ) . Were analyzed daily and continuously (every minute) concentrations of particulate material. The daily concentrations of ambient attended the Brazilian ANVISA standard for PM10 of 80 µg/m³, and international WHO PM25, of 25µg/m³. In analysis in continuous some high concentrations were found, especially in the reception rooms (P1 and P2). Were observed very high concentrations in P4 (Lab) during cleaning (> 600 µg/m³).
