With the arrival of autumn and winter, North China, Huanghuai and other places have recently suffered the most serious haze weather this year. According to the latest meteorological data, from the 28th to the 30th, under the influence of heavy fog, North China, Huanghuai and other places will have the strongest haze process since this autumn and winter. The air quality in many places is seriously polluted, which poses a serious threat to people's health and travel.
According to reports, during the main impact period of haze from the 28th to the 30th, light to moderate haze appeared in Beijing, Tianjin, most of Hebei, Henan, central and western Shandong, northern Anhui, northern Jiangsu, central Hubei, Guanzhong of Shaanxi, central and southern Shanxi, southern Sichuan Basin, central and western Liaoning, central Jilin, and southern Heilongjiang, among which Tianjin, central and southern Hebei, western Shandong, and northern Henan were all severely hazy.
The formation of this haze weather is mainly due to the interaction between specific climatic conditions and human activities. The economic and social activities of high-density populations inevitably emit large amounts of fine particulate matter (PM2.).5) Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate, and if it is affected by static and stable weather, it is very easy to have a wide range of haze.
In the face of hazy weather, we should take active protective measures. Try to minimize going out and reduce time spent outdoors, especially for the elderly and children, who should stay indoors as much as possible. If you need to go out, you should wear a mask to reduce the irritation of the respiratory tract by cold air. At the same time, keep indoor air circulation, open windows regularly for ventilation, and avoid the accumulation of indoor air pollutants.
In addition, we should start with ourselves to reduce pollutant emissions. Try to choose green modes of travel, such as walking, cycling or using public transport, and reduce the use of private cars. At the same time, pay attention to energy conservation and emission reduction, save electricity and water, and reduce energy consumption and pollutant emissions.
Let's take action together to protect the environment, reduce pollution, and create a better blue sky. Only when each of us actively participates in environmental protection actions can we jointly resist the harm of haze and make our lives healthier and better.
