| Resumen |
The objective of this study was to evaluate the effects of ventilation and temperature changes in university computer rooms on symptoms among students. Two classrooms had higher air exchange; two others had lower air exchange. After one week, ventilation conditions were interchanged between the rooms. The students reported symptoms during the last hour, on a seven-step rating scale. Measurements included room temperature, relative humidity carbon dioxide (CO2), PM10 and ultra-fine particles, illumination, air velocity, formaldehyde, nitrogen and ozone. Data were subjected to multiple regression analyses. It was found that computer classrooms may have CO2 above 1,000 ppm and temperatures above 22°C, and that these conditions may affect mucosal membrane symptoms, headaches and tiredness. Other findings are discussed. |
