What are the hazards of dust? How harmful is dust to the human body?

1) Harm to the human body. Workers who have been exposed to production dust for a long time will gradually increase the accumulation of dust in the lungs due to long-term inhalation of dust, and pneumoconiosis can be caused when it reaches a certain amount. Pneumoconiosis is one of the most important hazards of productive dust to the human body, long-term inhalation of free silica dust can cause silicosis, long-term inhalation of metallic dust such as manganese dust, beryllium dust, etc., can cause manganese lung, beryllium disease and other metal lungs; Long-term inhalation of coal dust can cause coal lungs, etc.

Long-term exposure to productive dust can also cause respiratory diseases such as rhinitis, pharyngitis, bronchitis, as well as mucosal damage, rash, dermatitis, and ocular conjunctival damage. For example, inhalation of lime dust can cause nasal mucosal damage; Inhalation of fibrous dust such as wool and hemp can cause tracheitis and bronchitis; Exposure to asphalt fumes in sunlight can cause photosensitive dermatitis, ocular conjunctivitis, etc. Inhalation of harmful substances and dust can also cause acute or chronic poisoning, such as long-term inhalation of manganese dust in welding operations, which can cause manganese poisoning, and lead smelting workers are prone to lead poisoning.

2) Harm to production. The dust in the air in the workplace adheres to high-level, precision instruments and meters, which can reduce the accuracy of these equipment; Attached to the transmission and running parts of machinery and equipment, the wear is strong and the service life is shortened; Dust can reduce the quality of certain chemical products, mechanical products, and electronic products, such as paints, films, miniature bearings, motors, integrated circuits, capacitors, televisions, video recorders, and cameras; It affects people's vision in the production process and reduces work efficiency. (3) Harm to the environment.

Dust floating in the air can cause other harmful substances to adhere to it, forming serious air pollution. Inhalation of organisms can cause various diseases, and the surface of cultural relics, monuments, and buildings will be corroded and polluted. In addition, large amounts of dust are suspended in the air, which can reduce the visibility of the atmosphere, promote the formation of smog, and affect the thermal radiation of the sun.

‍1.Pneumoconiosis, pneumoconiosis refers to a disease mainly caused by fibrosis of lung tissue caused by inhalation of productive dust during the production process. Due to the difference in the quality and quantity of inhaled dust, there are different degrees of harm.

There are many types of pneumoconiosis, 12 of which are classified as occupational diseases, they are: silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestososis, talc, cement pneumoni, mica pneumoni, potter's pneumoconiosis, aluminum pneumoconiosis, electric welding mixed pneumoconiosis, caster pneumoconiosis. 2.

Dustosis, some metals (iron, barium, tin, etc.) dust inhalation, can be a foreign body reaction in the lung tissue, and continue to slight fibrosis, but the harm to the human body is less, after getting rid of the dust operation, the lesion can gradually subside. 3.Lung lesions caused by organic dust, different organic dusts have different biological effects, such as causing bronchial asthma, cotton dust, occupational hypersensitivity pneumonia, mixed pneumoconiosis, etc.

In modern society, although the standard of living is constantly improving, but with the continuous development of industrial products, the environment in which people live has also been seriously polluted, many projects, in the process of production, will produce a large amount of dust, these dust float in the air, and the body contact with these dust, will have a great impact on the body.

Leads to poisoning. Different types of dust cause different hazards to the body, if the body inhales some soluble dust, then the dust will enter the body through the blood system, which can cause poisoning, and may also endanger the life of the patient.

Damage to the cornea, in the process of contact with dust, if some hard dust once it comes into contact with the eye, it will damage people's cornea and conjunctiva, tissue, in this case, it will lead to the symptoms of corneal opacity, and may even cause conjunctivitis, so we must pay attention to it, and try to stay away from these dusts.

Pneumoconiosis is caused by the body after inhaling a large amount of dust, which is mainly caused by long-term living in a dusty environment, resulting in changes in the diffuse interstitial fibers of the lungs. Pneumoconiosis is a relatively common occupational disease, which will have a great impact on the health of the body, so everyone should wear a mask as much as possible when living and working.

Affecting the health of the powder, after it has been in contact with the skin, it will have an adverse impact on the health of the skin, and may even clog the pores and may also cause the problem of dryness.

Dust will cause a lot of harm to the health of the body, we must have a correct understanding and understanding, in daily life to try to avoid these dust, if you have to work in this environment, then we must do a good job of relevant protective measures, as far as possible to wear eye masks and masks, so as to reduce the adverse effects of dust on the body.

The main hazards of dust to the human body include bronchitis, severe can cause pneumoconiosis, obstructive emphysema, respiratory failure, and cor pulmonale. Under normal circumstances, the nasal cavity, nasal mucosa, and bronchial cilia have a certain filtering effect on dust particles with large diameters in the gas, but for dust with a diameter of less than 5 microns, it can diffuse into the lower respiratory tract and be deposited in the bronchial mucosa, and will form pneumoconiosis nodules after being engulfed by macrophages for a long time, and form plaques with the development of the disease, affecting the function of lung diffusion and ventilation.

The hazards that may be caused by dust occupation are as follows: 1. Destruction of the normal defense system of the human body. 2. It can cause lung diseases.

4. Cause dust poisoning. 1) Silica dust (inorganic dust with a free silica content of more than 10%) may cause occupational diseases: silicosis.

2) Occupational diseases that may be caused by coal dust (coal silica dust): coal workers' pneumoconiosis. 3) Occupational diseases that may be caused by graphite dust:

Graphitus pneumoconiosis. 4) Occupational diseases that may be caused by carbon black dust: carbon black pneumoconiosis.

5) Occupational diseases that may be caused by asbestos dust: asbestosis. 6) Occupational diseases that may be caused by talc dust:

Talc pneumoconiosis. 7) Occupational diseases that may be caused by cement dust: cement pneumoconiosis.

8) Occupational diseases that may be caused by mica dust: mica pneumoconiosis. 9) Occupational diseases that may be caused by ceramic dust:

Ceramic dust. 10) Occupational diseases that may be caused by aluminum dust (aluminum, aluminum alloy, alumina dust): aluminum pneumoconiosis.

Dust refers to solid particles with a small diameter, which can be naturally generated in the natural environment, such as dust produced by volcanic eruptions, or can be generated by various activities in industrial production or daily life, such as a large number of dust particles produced by rock crushing in the mining process. Production dust refers to solid particles that are formed during the production process and can float in the air for a long time. After the formation of many production dusts, the surface can often adsorb other gaseous or liquid harmful substances, becoming the carrier of other harmful substances. Productive dust pollutes the working environment and affects the physical and mental health of workers.

1. Systemic damage: Long-term inhalation of higher concentrations of dust can provoke systemic diseases (pneumoconiosis) dominated by overflowing and progressive fibrosis in the lungs; If toxic dust is inhaled, it can be ablated on the bronchial wall and received, and carried from the blood to all parts of the body, causing systemic poisoning and severe damage to the central nervous system, respiratory system and digestive system. Similarly, there are also hazards in the paint mist produced by spray painting, so the spray paint mist treatment work also needs to be done well!

2. Part of the damage to contact or inhalation of dust, the initial effect on the occurrence of **, cornea, mucous membrane, etc., and a series of lesions. If the dust effect is on the respiratory tract, it can cause hyperfunction of the nasal mucosa and telangiectasia in the early stage, which will constitute hypertrophic rhinitis over time, and finally atrophic rhinitis due to the lack of mucosal nutrient supply. It can also constitute pharyngitis, laryngitis, trachea and bronchitis. The effect is **, can constitute acne, folliculitis, pyoderma, such as lead dust immersion**, will present some small red spots, called "lead rash" and so on.

3. Carcinogenesis induces dense exposure to dust such as nickel, chromium and chromate, which can cause lung cancer; Exposure to radioactive mineral dust can easily cause lung cancer; Asbestos dust can cause skin cancer.

People who work in widespread, persistent dusty environments are physically hazardous. This is because dust is solid particles with a very small diameter that can be inhaled through the respiratory tract and deposited in the lungs. If you work in such an environment for a long time, the productive dust in the lungs will be inhaled more and more for a long time, and the deposition in the lung tissue will cause a wide range of lung inflammatory reactions, such as pneumoconiosis, silicosis, and diffuse fibrosis of the lungs for a long time.

Moreover, lung function will decline, causing dyspnea, and even respiratory failure in severe cases, which will affect the normal life and work of individuals.

First, it has the greatest impact on the first, although there is protection, but the dust is still easy to be absorbed by the first. For example, it is easy to absorb during sweating or after sweating, causing itching.

Second, if the protection is not enough to injure the trachea and lungs through the nasal cavity, the trachea will become inflamed at least and the lungs will be suffocated at worst.

Thirdly, if the protection is not well received through the oral cavity, it can lead to stomatitis and even gastrointestinal diseases.

The hazards of dust, there are, the harm to the human body, the harm to the production of the harm to the environment, etc., the harm to the human body, the long-term exposure to the production of dust workers due to long-term inhalation of dust, the accumulation of dust in the lungs gradually increases, two, the harm to production, the dust in the air in the workplace, attached, advanced, precision instruments, one, table, three, the harm to the environment, the dust floating in the air, can make other harmful substances, attached to it, and so on.

The harm of dust is very large, if inhaled into the body, it will bring us different degrees of damage and cause different degrees of lesions, especially the respiratory tract is more common.

1.First of all, there will be varying degrees of pneumoconiosis. Long-term inhalation of dust can cause fibrosis of lung organs and tissues. The severity of the disease is determined by the amount of dust inhaled.

2.There are also some problems with the milder impact of dust, dust-deposition. It will also cause slight fibrosis of the lungs, but the impact on the human body is relatively small, and it will cause lesions of the respiratory mucosa, such as tracheitis, pharyngitis, laryngitis and so on.

3.Dust sticking to ** will also form some troubles, such as causing **folliculitis, acne, etc., and even inhaling heavy metal dust will also lead to poisoning.

Therefore, we must stay away from dust in our lives, and we must also take protective measures.

The harm of dust to the human body, according to its physical and chemical properties and the size of the particles, the amount of the amount of entering the human body and the different parts of the action, can cause different lesions, mainly some lung lesions. Among the respiratory diseases affected, the first common is pneumoconiosis, which refers to the fibrosis of lung tissue caused by inhalation of productive dust in the production process, and the patients are mostly exposed to silica dust 10 15 years after the onset of the disease, the course of the disease is slow, and the respiratory function of patients in advanced severe cases is seriously impaired, often complicated by cor pulmonale and tuberculosis, and the best ** needs to be replaced**.

It can also lead to the occurrence of asbestosis, which refers to the long-term inhalation of asbestos dust caused by pulmonary fibrosis and pleural fibrosis as the main lesions, and the main clinical manifestations of patients are cough, sputum, shortness of breath and chest pain, etc., and the symptoms and signs of pulmonary dysfunction and chronic cor pulmonale will occur in the late stage.

If you must work in such an environment, you must take protective measures to avoid the occurrence of diseases.

Dust hazards:

1. Hazards to the human body can cause occupational diseases

Production dust can cause different diseases according to its physicochemical properties and action characteristics. The lungs are one of the most important hazards of productive dust to the human body.

2. Dust pollution to the environment

Dust stains buildings and corrodes valuable ancient buildings. Dust that falls on the leaves of plants can hinder photosynthesis and inhibit its growth.

3. Dust hazards:

Dust refers to the instantaneous and rapid combustion of dust (** is a very rapid chemical or physical change process of matter, in the process of change quickly release huge heat and generate a large amount of gas, at this time the gas still exists in a limited space instantly, so there is a great pressure, the object around the ** point has a strong pressure, when the high-pressure gas expands rapidly**.
