Heavy pollution, its range is 0.4mg/m? —0.8mg/m? Compared with light pollution, the symptoms are more intense. Symptoms such as shortness of breath, sore throat and general fatigue usually appear within 24 hours to 48 hours, and plants will wither inexplicably in heavily polluted rooms, which can be used as a criterion for judgment.
