[real-time] wearing masks are unable to prevent Beijing will welcome the first time this year, ozone heavy pollution

Abstract: The environmental protection department stated that ozone itself is an unstable substance and that ozone has exceeded the standard in the environment. This is mainly due to the fact that various pollutants in the air continuously react and generate ozone at high temperatures. Therefore, it is also very simple to protect the ozone. It is to minimize the outback during the high temperature period in the afternoon. “Whichever is cooler,” it will minimize the harm of ozone to the human body.

On May 18, the highest temperature in Beijing reached 36.4°C, becoming the first high temperature day this year. With the high temperature comes serious ozone pollution, the environmental protection department said that on the 18th day, Beijing's ozone concentration has reached moderate levels of pollution, the weekend may even develop into severe pollution.

According to the meteorological department, on the 18th, the maximum temperature of the southern suburb observatory reached 34.7°C. Although there was no window paper to break through the high temperature line, temperatures above 35°C appeared in Beijing Chaoyang, Changping, Shunyi, and Tongzhou. The highest Mentougou Zhaitang once reached 36.4°C. The meteorological department stated that Beijing is still in a high-temperature yellow warning. The maximum temperature in the next few days is still expected to rise and fall at 35°C. Until Sunday, Beijing will usher in a light rain to improve, so it is absolutely necessary to do a good job of cooling off the heat. ready.

With the high temperature comes severe ozone pollution. The Xinhua reporter learned from the Beijing Environmental Monitoring Center that although the Beijing residents have been dying of PM2.5 recently, the air quality in Beijing still showed moderate pollution on the 18th. The main thing is ozone. The environmental protection department said that the ozone pollution in Beijing over the weekend may be even worse than these days.

According to reports, high concentrations of ozone can irritate and damage human mucosal tissues, such as the eyes and respiratory system. What's worse is that the masks and other protective measures that are commonly used cannot protect the gaseous pollutant ozone. The environmental protection department stated that ozone itself is an unstable substance and that ozone has been exceeded in the environment. This is mainly due to the fact that various contaminants in the air continuously react and generate ozone at high temperatures. Therefore, it is also very simple to protect the ozone. It is to minimize the outback during the high temperature period in the afternoon. “Whichever is cooler,” it will minimize the harm of ozone to the human body.
