Now, laser printers, electrostatic copiers, etc. are indispensable in the office, and these printing machines will release all kinds of fine particles of carbon powder, polluting indoor air. Nowadays, such devices are widely seen in homes, companies, and organizations. It is these machines that release large amounts of fine particles, heavy metals, and harmful gases. This has caused various office syndromes to become popular in countries around the world. Typical symptoms are respiratory infections, headaches, and Blood changes.
In general, toner cartridges used on the market contain carbon black, iron oxide, and polyester in addition to carbon powder, such as nickel, cobalt, and mercury. These metal dusts are harmful to the human body. , Different product content varies. In addition, carbon powder also contains well-known carcinogens, such as benzene, aldehydes, styrene and so on. The color print toner is even more toxic, such as tributyltin, which can endanger the secretion of human hormones, which can lead to a decrease in the number of sperm in men and infertility in women. Such harmful substances cannot be ignored. In 2003, Germany prohibited the use of this substance in the shipbuilding industry.
In fact, more than ten years ago, a study published by the Spanish scientists in the "The Lancet" magazine warned that the dust released by an electrostatic photocopier can cause lung disease. Shortly thereafter, the US Environmental Research Agency EPA also came to a similar conclusion. As early as 2003, the Dortmund Medical and Medical Protection Agency in Germany carried out a test: inhaling carbon dust in test rats, and soon afterwards, tumors grew in the lungs of test rats. Similarly, the Labor Protection Institute of Bonn conducted similar experiments on mice and guinea pigs, but found no abnormalities. Both tests, however, found that after the animal inhaled the fine particles released by the device, it produced an "inflammatory reaction." Unfortunately, so far, people have not seen any hints about harmful substances contained in the carbon powder on the operating instructions of these devices.
Toner particles are harmful to the human body. Toner particles are so tiny that they are easily suspended in the air and enter the body through the respiratory tract. Furthermore, carbon powder cannot be melted in the human body and it is extremely difficult to excrete it. After the leaked toner particles are inhaled by the human body, they are difficult to excrete through the metabolism. The harmful substances can even penetrate deep into the lungs and destroy the lung tissue, which is more harmful than the secondhand smoke. Therefore, long-term inhalation or one-time inhalation is very prone to respiratory distress, insomnia, headaches, dizziness and other problems, and more serious is the possibility of causing severe diseases such as silicosis or incurable cancer.
On the other hand, printing machinery can also harm the environment. Due to the action of the high-voltage electrostatic field, they generate a large amount of organic waste gas such as benzopyrene and dimethylnitrosamine. These organic gases are pathogenic, teratogenic, and carcinogenic. A recent study by the British Allergy Foundation researchers also pointed out that office equipment also releases ozone gas. Although ozone can reduce the harm of solar radiation, the high ozone concentration is a scourge.
