There are a lot of flying flakes on the streets in the spring in the north, what are the hazards of

Fly floc is the flying willow flocculent, some cities in the north because of the planting of more willows and poplars, so in the spring, catkins and poplar floc are often flying all over the sky, not only affect the sight of people when traveling, but also easy to fall on people, adhere to people's **, some ** people who are prone to allergies will appear peeling, itching and rash and other symptoms, without wearing a mask inhaled fly floc is also easy to cause tracheitis and other respiratory diseases.

In some cities in the north to spring, there will be a special phenomenon of urban flying, willow flying will be blown by the wind like snowflakes flying all over the sky, with the sunny spring has to be said to be a romantic and special scenery. But good-looking is only a superficial phenomenon, flying flocculent brings more harm, the first point is that it will fall everywhere is to affect the cleanliness and sanitation of the city, sanitation workers sweep the flying floc on the ground to spend a lot of effort, in addition to the flying floc to personal health and public safety also has a certain harm.

The catkins in cities that endanger personal health appear to be small and scattered, and can drift far away with the wind; Poplar catkins are easy to cling to and look a bit like cotton. When people walk outdoors or on the street, the flying flotsam in the air can easily enter people's nostrils, eyes or be inhaled into their mouths, causing discomfort and even inflammation. Some people who are prone to allergies will also have itchy and red rashes because the fly flotsam falls on the upper face; People who accidentally inhale fly floc into the trachea may also aggravate respiratory diseases such as bronchitis and asthma.

When the wind stops, the fly will pollute the city's sanitation when the wind stops, which will be hard for sanitation workers. In addition, flying flotsam will also block the view of pedestrians and drivers, increasing the probability of traffic accidents; In addition, the fly can also affect some high-precision instruments, block the heat sink on the car water tank, etc.; Fly floc is also a highly flammable substance, no matter if it falls on the **, it will increase the likelihood of fire.

The main harm is that it is an allergen, which can cause reactions such as runny nose, cough and even asthma when inhaled into the nose. Some people will also have ** itching, red conjunctiva symptoms, flying floc can also cause seasonal allergic rhinitis.

Flyings may cause respiratory infections that can make people who inhale them sick, such as coughing or runny nose, and in severe cases, affecting sleep.

Flying floc may make people allergic and cause itching, which is also a very serious harm.

Flying flotsam can also affect the environment, destroy the ecological environment of the city, and make the city look a little dirty.

The first point is that inhaling into the nose will cause poor breathing, it will cause suffocation, which is very harmful, and the second point is that when you open your mouth and talk and run into the stomach, it will form bacteria, which is very bad for the body.

The flying flocculent sky will affect people's travel, sight when driving, and it is easy to fall on people, sticking to people's **, and some **people who are prone to allergies will have symptoms such as peeling, itching and rashes.

Although spring is a season of spring flowers, everything recovers, and everyone likes to go out to enjoy the flowers. But it is also a very nasty season for allergy sufferers, as the pollen in the air and the flying poplar catkins are actually very nasty and can give people with allergies a red rash. In the spring, the north also ushered in the difficult flying season, when a gust of wind blows, the sky seems to be snowing, and there are white hairs everywhere.

Don't underestimate these flying catkins, the harm is very great, for example, in the past news, these catkins piled up under the car, and as a result, because of a little spark, the entire parking lot of the car burned. <>

Every year in spring, these white catkins will affect people's normal life, because many people are allergic to poplar catkins and catkins, so in the spring they will have rhinitis, which is very painful. Poplars and willows are some native trees in the north, these trees can reduce noise, can be made and can be cared for, have good landscape value and ecological value, but there will be 2 3 weeks of flying flocculation every year, which is really annoying. <>

The fly itself is non-toxic, but it is always floating in the air and being blown around by the wind, so it is very likely to spread some germs. Whenever the catkins in the air are fluttering, some dirty things and dust on the ground will also drift into the sky together, and the air quality will drop greatly at this time, which is very harmful to human health. Those who are allergic will have a small red rash on their body at this time, and they will also be red, swollen and itchy, and even molt to cause chronic bronchitis.

And when the weather is dry in spring, all these catkins will fly into the air, which is a flammable product, and it is very easy to burn if it encounters an open flame, and the speed of spreading is very fast, and it is easy to cause disasters. If people on the road litter cigarette butts, or if someone deliberately ignites them, the situation is not easy to control. These catkins are also very easy to enter the condenser of the car, as well as the water tank, which is easy to cause the vehicle to malfunction, which may cause the temperature of the engine to rise or the air conditioner will not refrigerate, and even lead to a sudden fire in the vehicle, so it is also easy to cause potential safety hazards, and we must remove it in time if we see it.

Catkins are very harmful because it is simply a torture for rhinitis patients, which can also affect a person's breathing condition and can also make some people have difficulty breathing. It also has certain disadvantages for the lungs of people.

It is easy to cause allergies in many people, and there are some rhinitis and allergy patients who are very painful at this time, there is no way, normal going out on the street, need to take drugs constantly, and it is easy to cause fire.

The harm caused by catkins is very great, it may carry some diseases, it will make people allergic, it may also pollute the ecology, and it is likely to carry germs.

Why do catkins drift away with the wind.

The seeds of the willow tree are wrapped in catkins and you can take a closer look. The willow tree spreads the seeds wrapped in catkins by the force of the wind.

Weeping willow fluttering is not very serious, dry willow is very serious, in fact, it is their seeds are falling, the seeds of the willow family have hairs on the bead stalk, which can be blown by the wind to facilitate the spread, their male flowers are soft wattle-shaped, that is, we usually see caterpillar-like flowers, but willows have nectar glands are insect-borne flowers, and poplars are wind-borne flowers.

Since the 60s of the last century, a large number of poplar trees have been planted in the urban and rural areas of Beijing. Poplars grow fast, but have a short lifespan, generally starting to age after 20 years, with dry canopies and early defoliation"Geriatrics", the more"Advanced age"poplars, the more fly flotsam is made. The poplar trees planted in Beijing are more than 30 years old.

In the spirit of"Multi-forest species, multi-tree species, multi-plant, multi-color, multi-level"The Beijing Forestry Department has been implementing the requirements since 2002"Over-mature forest renovation project"The old poplars that renew the spring floc will be phased out, and a large number of male poplars that do not fly flocculent, as well as tree species such as Pinus tabuliformis, Arborvitae orientalis, and locust trees, while paying attention to the collocation of tree species, spatial configuration and seasonal changes, highlighting the landscape effect. It is expected that after 3 to 5 years, the situation of flying flotsam flying in densely populated areas and large areas in Beijing will be gradually controlled.

Because there is a willow bar, there are many catkins.
