What are the effects of inhaling metal dust on the human body? What should be done to prevent it?

It can cause heavy metal poisoning, and a dust mask should be worn.

Long-term inhalation of dust will cause harm to the lungs and cause pneumoconiosis (pneumoconiosis formed according to the different dust inhaled is habitually called silicosis, asbestosis, etc.). Although dust does not cause disease immediately, it can still cause problems over time, so it is important to pay attention to it.

The following points should be noted.

1.Living and working in a dusty environment, once the dust enters the body through the respiratory tract, it will cause a lot of bad harm to the body, such as lung diseases, then you need to pay attention, first of all, the external prevention method is to wear a mask, the mask can filter out a part of the dust, prevent the dust from entering the respiratory tract.

2.It is to eat more foods that clear the lungs, such as pig blood, fungus, etc., such foods can help remove some of the dust in the lungs, which is still very helpful to the body.

3.It is necessary to drink more water, which can take away a part of the dust, so that the dust that has not yet entered the lungs can be discharged from the body, reducing some of the damage.

The glaze of porcelain contains heavy metals such as lead, mercury and arsenic, and the glaze of the glaze is in direct contact with food and drinks, and the heavy metals in the glaze will gradually penetrate into food or drinks, and regular use will cause chronic poisoning of heavy metals.

Tin is similar to aluminum, excessive intake will affect the development and function of the nervous system, the nervous system of chronic poisoning patients will be seriously damaged, the probability of dementia will also be greatly increased, the tin pot is generally not a big problem to temporarily contain neutral liquid, but if the long-term storage of acidic or alkaline liquid, tin will be dissolved in large quantities, causing harm to the human body.

Heavy metals are metals with a specific gravity greater than 5 and a density greater than that, such as gold, silver, lead, mercury, cadmium, arsenic, chromium, etc.

Chromium can cause bronchial asthma, which can lead to cancers of the respiratory system.

Cadmium poisoning, the main symptoms are nausea, vomiting, diarrhea.

The effects of lead compounds on the human body are mainly on the nervous system, kidneys and blood system, and can also cause kidney failure and affect mental development.

Arsenic poisoning can cause hair loss, pigmentation, and possibly cancer. There is also acute arsenic poisoning, arsenic trioxide, that is, arsenic poisoning should be known.

Mercury is the most harmful to the human body and can cause nervous system disorders, liver failure, and more.

In addition, many metal ions can also cause the denaturation of human proteins, such as barium ions, divalent copper ions, and so on.

The harm of dust to the human body can cause different lesions according to its physical and chemical properties and the amount of dust entering the human body. Such as respiratory system diseases, local effects, toxic effects, etc.

There are four manifestations of occupational respiratory diseases:

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, and they are:

Silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestososis, talc pneumonosis, cement lung, mica pneumoni, potter's pneumoconiosis, aluminum pneumoconiosis, electric welding mixed pneumoconiosis, caster's pneumoconiosis.

2.Dustiness.

After inhalation of some metals (iron, barium, tin, etc.) dust, it can react with foreign bodies in lung tissues and continue to be slightly fibrotic, but it is less harmful to the human body, and the lesion can gradually subside after being removed from the dust operation.

3.Lung lesions caused by organic dust.

Different organic dusts have different biological effects, such as causing bronchial asthma, cotton dust, occupational hypersensitivity pneumonitis, mixed pneumoconiosis, etc.

4.Tumors of the respiratory system.

The local effect of dust refers to the action of dust on the mucosa of the respiratory tract to cause atrophic lesions; In addition, pharyngitis, laryngitis, tracheitis, etc. can also be formed; It can form acne, folliculitis, pyoderma, etc.; Metal and abrasive dusts can cause corneal damage, resulting in corneal dysesthesia and corneal opacity; Asphalt soot can cause photosensitive dermatitis when exposed to sunlight. The poisoning effect of dust refers to the poisoning phenomenon caused by inhalation of toxic dusts such as lead, arsenic, and manganese.

For the hazards of dust, the following technical measures can be used to prevent dust in the production process:

1.Innovation.

Reforming process equipment and process operation methods and adopting new technologies is a technical measure to completely eliminate dust pollution and do a good job in dust prevention. In the process reform, the first should be the root cause of the dust hazard in the production process, and then the measures to eliminate or reduce the harm of the dust through treatment.

2.Wet dust protection.

It's a simple, cost-effective and effective way to prevent dust. Dust is easy to absorb, coagulate, and increase weight after encountering water, which can greatly reduce the generation and diffusion of dust and improve the air quality of the working environment.

3.Seal the dust source.

The effective closure of the dust source is an effective technical measure to prevent dust from escaping, and it is often used in conjunction with ventilation and dust removal technical measures.

4.Ventilation and dust removal.

This is the most widely used and most effective technical measure in industrial production. Ventilation and dust removal is to effectively control the dust source by ventilation, and extract the dust-containing gas, which is purified by the dust collector and discharged into the atmosphere, so that the dust concentration of the air in the operation area meets the requirements of the health standard, and the exhaust gas meets the requirements of the emission standard.

5.Personal protection.

This is a complementary measure. Usually on the basis of other technical measures, various protective equipment (such as masks, dust masks, dust masks, dust helmets, etc.) are used to further prevent the inhalation of dust and reduce the harm of dust to the human body through various protective equipment (such as masks, dust masks, dust masks, dust helmets, etc.).
