The average concentration is 244 μg/ m3 and 171 μg/ m3, respectively, and the background concentration is 166 μg/ m3 and 110 μg/ m3, respectively. In the iron foundry plant, when the middle frequency furnace opened, the instantaneous PM10 and PM2.5 mass concentrations increased significantly to 10 mg/ m3 and 7 mg/ m3, respectively.
