The harm of selenium drum?
1, harmful toner component
Generally speaking, in addition to carbon black, iron oxide and polyester, the carbon powder used for toner cartridges in the market also contains many metal dusts harmful to human body, such as nickel, cobalt and mercury, and the content of different products is different.
2, carbon powder contains carcinogens
Carbon powder also contains well-known carcinogens, such as benzene, aldehyde, styrene and so on. Color printing toner is more toxic, such as tributyltin, which can endanger the secretion of human hormones by a few parts per million, which will seriously lead to the decline of male sperm count and female infertility. ?
3. Carbon powder particles are harmful to human body.
Toner particles are very small and easily suspended in the air and enter the human body through the respiratory tract. Moreover, toner cannot be melted in the human body, so it is extremely difficult to be excreted.
After the leaked toner particles are inhaled by the human body, it is difficult to excrete them through metabolism, and harmful substances can even go deep into the lungs and destroy lung tissue, which is more harmful than second-hand smoke.
Therefore, long-term inhalation or one-time inhalation is very easy to cause respiratory diseases, insomnia, headache, dizziness and other troubles. More seriously, it may cause serious diseases such as silicosis or incurable cancer.
4. The potential harm of filling carbon powder to human health.
Without strict environmental protection, the selenium drum is filled with powder, and there will be small particles (invisible to the naked eye) flying in the air. After repeated inhalation, the probability of cancer is higher than that of normal people 10%.
When polyethylene/polypropylene paraffin, a surface modifier, is inhaled into the body, its small molecular particles will be absorbed into the blood circulation system and eventually colonized in the kidney, which is extremely difficult to discharge (because carbon powder is insoluble in water), thus the probability of inducing diseases such as kidney calculi is three times higher than that of normal people. ?
5, printing machinery will also harm the environment.
When they work, due to the action of high-voltage electrostatic field, a large number of organic waste gases such as benzopyrene and dimethylnitrosamine are produced. These organic gases are pathogenic, teratogenic and carcinogenic.
A research report published by researchers from the British Allergy Foundation also pointed out that office equipment will also release ozone gas. Although ozone can reduce the harm of solar radiation, too high ozone concentration is a disaster.

Protective measures against the dangers of toner cartridges?
1, try to use regular companies or brands of environmentally friendly toner cartridges.
2. When you are not sure whether the filled toner is non-toxic, please keep the printer away from the human body and place it in a ventilated place, such as a copier. ?
3. Try not to fill the workplace with toner. If necessary, the filling process should be carried out under strict environmental protection in the factory, and qualified and standardized toner should be filled. ?
4. If it cannot be filled under environmental protection, try to fill it in a windy place in the wild and burn the waste powder and materials stained with carbon powder. ?
In the workplace, keep some green plants, because plants can absorb carbon dioxide, release oxygen, adsorb dust, sterilize and other functions, which can improve indoor air quality and be beneficial to physical and mental health.
