摘要：Indoor air quality in schools is one of the main concerns for the health of children. Inside a classroom there are high levels of different pollutants concentrations along with high levels of particulate matter (PM). Many studies showed that PM can severely affect the health of children, especially those with asthma problems. In this article an experimental campaign was conducted in two identical classrooms as size, orientation and number of persons with the purpose to evaluate the PM concentration. The only difference is one classroom is ventilated with fresh air while the other one is not. With two GRIMM measurement equipment we have measured for two days the indoor levels. In fact, the ventilation system was found efficient especially for larger particles (PM10) of dust while for smaller ones (PM1) the results were similar. We have calculated a reduction of PM concentration of 10%,...,12% on the mean values. It is concluded that ventilation of schools has multiple benefits on the indoor air quality.
