The only solution is 1: reduce outdoor activities and stay indoors.
Unlike the prevention of PM2.5, wearing a mask is ineffective in preventing ozone. The environmental protection department suggested that outdoor activities should be avoided at 2 or 3 pm when ozone pollution is the most serious. Especially children, the elderly and other frail people, who really need to go out, should be well protected. According to the detection of Environmental Protection Agency (EPA), indoor ozone concentration is generally 50% lower than outdoor ozone concentration. If the room is well sealed and air conditioning system is adopted, the ozone concentration will be lower.
In addition, some oxygen in the air will be converted into ozone by sparks generated during motor operation, xerography and TV work. Therefore, the electromechanical room, electrostatic copier room, computer room, etc. They are all places with high ozone incidence, but pay attention to ventilation. Use less photoelectric copiers and sprays (such as pesticides and hairspray instead of hairspray). ) at home.
