A variety of “magic scenes” have caused many citizens to worry about the air quality in Nanchong. Some people even wear masks to travel. At 4:48 p.m. yesterday, the Municipal Meteorological Observatory issued an early warning signal that it was expected that there would be moderate defects in some parts of the city within 24 hours. Please pay attention to the adverse effects of the weather.

Yesterday issued a yellow warning signal

At 8 o'clock in the morning yesterday, the reporter observed that at the Wenhua Road in Shunqing District, basically every one passing 10 passersby would wear one or two masks. According to Fan Xinming, a passerby who wears a mask, he is a college student in the city. Recently, his classmates bought a few masks on the Internet and they usually wear them. As for how much benefit he could have, he didn't know much about it. He just felt that a layer of protection was better. At 3 pm, the reporter looked from the side of the Jialing River to the other side. The visibility in the distance is still not high, and the high-rise buildings are still like clouds.

At 4:48 p.m. yesterday, the Municipal Meteorological Observatory issued an early warning signal in obituary yellow: It is estimated that moderate turbulence will appear in some places in the city within 24 hours and moderate air pollution will be easily formed. It is reported that this is the first warning signal issued by the city this winter.

According to the experts of the Municipal Meteorological Observatory, in the next few days, the city will still be dominated by fine weather. The situation of atmospheric pollution will not be easily improved. For now, the light rain on Sunday may not only fail to disperse the smog, but also because the rainfall is too small. , increase the haze, because the moist air to the suspended pollutants "put on" a layer of "water coat", more likely to cause the accumulation of pollutants, so that the concentration of haze increased.

Increased number of respiratory diseases

"This weather sometimes leaves the door uncomfortable," said Liu Zhendong, a citizen. He could easily cough when he arrived in the winter. When he got out, he felt uncomfortable throat and coughed even more. According to Jia Jun, deputy director of respiratory medicine at the Central Hospital, he admitted more than 70 outpatients yesterday. This has a certain correlation with the recent decline in air quality. The number of patients with respiratory diseases has increased significantly, and the patient’s condition has become relatively serious. . Some young people are still sick when doing extended exercises in such weather. Now the beds for respiratory medicine need to be booked in advance.

“Citizens who ride bicycles or motorcycles, or walk citizens, are best to wear masks when they go out.” Jia Jun said that wearing masks is a good preventive measure in case of hazy days, and it’s best to wear professional protection.霾 masks.

Fog days should not wear contact lenses

Many citizens know that it is necessary to pay attention to wearing masks, entering the house to wash their faces, etc., but they do not expect that while protecting the respiratory system, the eyes also need to be protected. “Smog and dry eyes can easily be aggravated.” According to Zeng Guanpeng, an ophthalmic lecturer at the North Sichuan Medical College, the mucous membranes of the eyes are sensitive to dust and chemical substances. The main components of the earthworms are dust, sulfuric acid, and nitric acid in the air. Substances, chemical granules, These substances are apt to cause irritation to the eye mucous membrane system and thus lead to non-infectious conjunctivitis. Many patients with eye diseases will also worsen in smog days.

"Contact lens wearers need special attention." Zeng Guanpeng said that as far as possible, do not wear contact lenses fog, because when wearing contact lenses, tear fluid deterioration, in the case of air pollution, dust and particles can not be washed away by tears, It easily accumulates in the conjunctiva, leading to ocular allergy or infection, and even causes eye diseases such as keratitis.

In addition, smog eyes can blink more. Because there are many harmful particles in the haze that are absorbed in the cornea, blinking can make the cornea wash away with tears, reducing eye damage. There is eye discomfort in hazy weather. Do not buy eye drops on your own, because the composition of smog is very complex. If you do not have the right medicine to prevent the disease, you can use the eye drops that relieve the eye under the guidance of a doctor. Discomfort, prevent eye diseases. (Reporter Wang Zhiqin)
