A survey on the indoor air quality of schools was conducted on a total of 10 schools in each location, such as industrial zones, roadside zones and clean zones of the Jeonbuk Province. Regardless of their location, 75% of the schools were not suitable to the environmental standard, and five schools were inadequate in both the first and the second half measurement results. Compared to the public facilities survey conducted by the Jeollabukdo Institute Health and Environment Research from 2008 to 2016, the concentration of CO2, total airborne bacteria (TAB), and PM10, with the exception of HCHO, was higher in school classrooms than in any other public facilities. The correlations between pollutants and test items demonstrated that total airborne bacteria (TAB) were significantly correlated with the degree of ventilation, and the PM10 was correlated with the cleaning status, respectively. Although the other test items of indoor air quality in the school were measured in the same way as the public facilities measurement methods, the PM10 is applied in accordance with the simplified method. In order to investigate the difference between the measurement methods, the results were compared at the same point at the same time. When comparing the concentrations of PM10, the gravimetric method, which is a public facilities measurement method, showed a significant difference from the light scattering method, which is a method of measuring PM10 in schools. By comparison, it was confirmed that the light scattering method was measured lower than the gravimetric method. The light scattering method is useful for confirming the change of the particulate matter, but it is considered difficult to judge the concentration of the particulate matter in the classroom by the instantaneous measurement because of the potential error caused by high humidity, etc. Secondary pollution ions were measured at 17.1% ~ 40.5% in the industrial zone schools, 7.4%~27.4% in the roadside zone schools and 8.1%~21.8% in the clean zone schools, The percentage of pollution ions were not clearly distinguished by location.
