What should be paid attention to in the dusty weather, and the harm of the dusty weather to people

First, pay attention to the weather forecast, when there is strong dusty weather, friends with respiratory diseases are better not to go out.

When the wind and sand rise, close the doors and windows in time. If you must be outside, it is best to use a dust-proof and filter mask to reduce the amount of sand and dust you inhale.

Second, in the event of a strong sandstorm, drivers on the road should not rush, but should park in a low-lying place and wait until the strong wind has passed before driving.

Third, when people return home, they can rinse their mouths with water, clean their nasal passages, reduce the chance of infection, and take medicine and rest in time if they feel cough, phlegm, or fever. If these symptoms do not resolve within a period of time, you should go to the hospital.

Fourth, in this dusty season, the weather is dry, and the moisture on the surface is very easy to lose, resulting in roughness. Dust is prone to clogging after entering the pores, and if it is not removed in time, it may cause acne; People with allergies are also prone to various allergic dermatitis and rashes. Therefore, it is necessary to wash the face in time and apply moisturizing skin care products.

In addition, drinking more water can replenish the lost water in time and accelerate the discharge of various metabolic wastes in the body, which is very beneficial to health care and general health.

Floating dust weather is the lowest intensity of sandstorms, which is a weather phenomenon formed by the remote generation and transmission of sandstorms or local sand blowing weather, when the intensity is weakened and the coarse particles in the sand and dust are gravity settled, and the fine particles are continued to be transported and floated in the air. When the wind speed continues to decrease, the suspended dust particles will settle to the ground, so it is commonly known as "falling yellow sand".

In dusty weather, distant objects are earthy yellow, and the sun is pale or yellowish; The wind speed is not very high, level 4 or lower; Visibility is less than 10 km and more than 1 km. Floating dust and blowing sand deteriorate the surrounding environment and have an important impact on human health, especially the respiratory system.

Long-term exposure to floating dust weather, including our eyes, nose, throat, etc., will be harmed to a certain extent. Don't think that PM10 is safe, because too much inhalable particulate matter can cause our ear, throat, nose and throat to be invaded by particulate matter, and when the particulate matter reaches a certain amount, it will cause health problems.

Floating dust is a weather phenomenon in which a large amount of fine sand and dust floats in the air, turning the sky into an earthy yellow color. These floating sand and dust are mostly caused by sandstorms and blowing sand.

This weather condition is very harmful to the human lungs. According to the meteorological department, the difference between a sandstorm and floating dust or blowing sand is visibility, and only when the visibility is less than 1 km can it be considered a sandstorm.

According to the meteorological department, the difference between a sandstorm and floating dust or blowing sand is the visibility of the burn, and only when the visibility is less than 1 km can it be considered a sandstorm.

In meteorology, the floating dust, the weakest is called the floating dust weather, the floating dust is due to the distant or local sandstorm or sand, dust and other fine particles floating in the air and formed, commonly known as "falling yellow sand", when the distant object is yellow, the sun is pale or pale yellow, the visibility is less than 10 kilometers, more than one kilometer, basically there is no obvious wind.

Causes of formation:

Dust in the weather refers to the suspended particulates in the air with a diameter of less than 10 microns and can float in the air for a long time, it is the most common sail pollutant in the air, usually we call it particulate pollution.

Most of these particulate pollutants are caused by human activities, such as black smoke, white smoke, red smoke, yellow smoke, etc. floating in the sky over industrial cities, and a large amount of particulate matter suspended in the air is released by the combustion of coal and fossil fuels, which seriously pollutes the atmosphere.

About 500 million tonnes of particulate matter are emitted into the air worldwide each year, mainly from fuel combustion and industrial exhaust gases. It is estimated that for every 1 ton of cement produced, 6 5 kg of floating dust will be discharged.
