Previously, the monitoring results were announced at 8:00 a.m., most areas had good air quality. However, as the afternoon and evening go, the amount of fine dust is generated, so some areas increase pollution at an average level.
Areas with good air quality do not affect health; areas with average, only affect sensitive groups. When traveling to areas with an AQI at an average level, people should wear standard masks to limit fine dust affecting their health.
