Recently, Beijing has been locked up by the haze. An aunt warned her with frosty yellow, and the news of the big square dancing in the square in front of the Yuanmingyuan Park attracted everyone's heated discussion.
On the afternoon of the 14th, the official upgraded the air pollution warning on the 14th. The city’s air quality has remained at a level of heavy pollution. The data show that the real-time concentration of PM2.5 in most parts of Beijing is above 200 μg/m3, and the real-time concentration of PM2.5 in some sites has exceeded 300 μg/m3.
Although anti-fog and haze masks have a defensive effect on smog, long-term exposure of humans to smog still poses risks. When we hope to exercise outdoors, we should try our best to choose the time when the air quality is better.
