Which season is the most serious ozone pollution?

Ozone pollution is the most serious in summer.

Ozone pollution generally starts from April every year and lasts until 10, with the highest concentration from June to August. Summer weather is more suitable for photochemical pollution, with high temperature and strong ultraviolet rays. The pollutants emitted by motor vehicles contain a lot of nitrogen oxides and volatile organic compounds. Under the irradiation of sunlight, they will have a series of reactions to generate ozone.

Ozone pollution is harmful to respiratory tract and eyes, and the impact on allergic people should not be underestimated. Different from PM2.5 pollution, ozone pollution days often look good, sunny, blue sky and white clouds, so the harm of ozone to people in summer is the most invisible. With the increase of sunshine, the ozone concentration increased continuously, reaching the peak at about 1 at noon, remaining high at 2~3 pm, and gradually decreasing with the weakening of solar radiation at around 5 pm.

How to reduce ozone pollution

Ozone in the atmosphere is difficult to control. The most effective way to reduce its harm to human body is to reduce going out in summer afternoon and try not to open the window.

Indoor, because of the lack of sunlight, ozone can not be produced continuously. On the other hand, indoor ozone can react with organic compounds containing unsaturated carbon-carbon bonds, such as rubber, styrene and unsaturated fatty acids, and soon disappear.

However, except where there is a laser printer in the office, because the laser printer contains ultraviolet light source, which can ionize strong light to produce ozone. It is recommended to put it in a ventilated place. For sensitive people who have to go out, such as asthma patients, wearing masks can filter ozone to some extent.
