Anonymous users2024-02-13The 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, 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 pneumonitis, mixed pneumoconiosis, etc.
4.Respiratory tumors 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: 1Technological innovation Reform of process equipment and process operation methods, the adoption of new technology is a complete elimination of dust pollution, do a good job in dust prevention work of technical measures.
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 Prevention This is a simple, cost-effective and effective dust prevention measure.
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.

Anonymous users2024-02-12Hello! We'll be happy to answer for you. Toxic metal dust and non-metal dust (chromium, manganese, cadmium, lead, mercury, arsenic, etc.) can cause poisoning and death after entering the human body. Inhaling manganese dust can cause toxic pneumonia; Inhalation of cadmium dust can cause emphysema and osteomalacia.
Non-toxic dust is also very harmful to the human body. If a certain amount of dust is inhaled for a long time, the dust is gradually deposited in the lungs, which causes the lungs to produce progressive and diffuse fibrous tissue, and respiratory diseases appear, which are called pneumoconiosis. Inhaling a certain amount of silica dust will harden the lung tissue and cause silicosis.
I guess you slept on the mat with your bare back. In a word, it's a cold. You can use "safflower oil" to pinch the back and use the back of your palm directly to the affected area. Sleeping on your stomach Do not roll over when you sleep at night.
If flour is not harmful to the human body, it must be fake, if flour passes through our nose and into our lungs, then it will cause harm, if flour enters our stomach through our mouth, it will become our food. Some people work in the flour mill, there must be more dust in the flour mill, it can also be said that there is more flour, when we go to work, generally speaking, the company will require us to wear masks, but sometimes even if we bring in masks, it is inevitable that some particles will enter our lungs, which is easy to cause this respiratory infection. <> >>>More
First, it can prevent and alleviate hyperviscosity Scientists have used hemorheology and hemodynamics to study the relationship between blood and blood donation, and found that insisting on long-term appropriate blood donation, especially the single donation of red blood cells and platelets and other formed components, can significantly reduce blood viscosity, speed up blood flow, and improve cerebral blood flow, so as to alleviate or prevent hyperviscosity, so that people feel relaxed, clear-headed, and energetic. Second, it can prevent and reduce the occurrence of cardiovascular and cerebrovascular diseases An expert in Qingdao has conducted a controlled study on blood rheology on 127 multiple blood donors, 87 patients with hypertension, and 60 patients with mechanical and bloody stroke, and the results show that blood donors have a positive effect on reducing the occurrence of cardiovascular and cerebrovascular diseases; In a Finnish study of 278 men aged 42 to 60 years, those who had donated blood were 86 per cent less likely to develop coronary heart disease after five years than those who had not. In another group of studies, 1532 people who donated blood 1 or 2 times were followed up and observed, and the results showed that only one person had acute myocardial infarction, and the incidence rate was significantly higher than that of the blood donation group among 2306 people who donated blood during the same period. A study by a cardiovascular disease research group in the United States has shown that the risk of cardiovascular disease in blood donors (men) is only 1 2 in non-donors over a 3-year period. >>>More
Log furniture without any chemicals is best for the human body and does not do any harm.
Liquid mosquito coils are the same as the ones on point. It is still harmful to the body. It is still recommended to use a mosquito net. Or close the window and light it 1-2 hours before bedtime. Wait until half an hour before going to bed before opening the window. The first 3 months of pregnancy are the most important.
