Previous issue date: 2015-08-25 / Objective: To describe the levels of pollution in public schools from the city of Porto Alegre. Methods: Thus, the aim of this work was to investigate the relationship between weather conditions an air quality of some public schools in Porto Alegre. Indoor and outdoor particulate matter concentrations were measured and analysed throughout the four seasons. Mobile devices were used to measure particulate matter concentrations in nive microenvironments near schools and in the routes used by students. Temperature, humidity and wind were also measured. Results: The particulate matter concentrations in the nine microenvironmets were similar and mostly higher than the tolerated level recommended by the World Health Organization (WHO). Conclusion: It was observed that only in the autumn season the particulate matter concentrations remained close to the exposure levels recommended by WHO for 24 hours. / Materiais e m?todos: Foram inclu?das nove escolas p?blicas de ensino fundamental da cidade de Porto Alegre-RS, que foram georreferenciadas e demarcadas tr?s rotas para realizar a coleta de material particulado em dois turnos em quatros esta??es do ano. Resultados: Foram avaliadas concentra??es de material particulado de 2.5 micrometros em movimento, em tr?s rotas de nove microambientes em quatro esta??es clim?ticas, e tamb?m dois pontos fixos no interior de salas de aula. As concentra??es de pico de material particulado foram realizadas em momento de criticidade de aumento de deslocamento em que as crian?as ficam expostas ao se deslocarem para escola. Os valores de pico no nove microambientes diferenciaramse entre si e mantiveram-se elevados em tr?s esta??es clim?ticas diferenciando-se no outono. Conclus?o: Os resultados do presente estudo demonstram achados similares nas concentra??es de pico de material particulado de 2.5 nos nove microambientes indoor e outdoor.
