Toner cartridge used in addition to the composition of carbon black, iron oxide and polyester, but also contains a lot of metal dust, such as nickel, cobalt, mercury, these metal dust are harmful to the human body, different products vary in content. In addition, carbon powder also contains well-known carcinogens, such as benzene, aldehyde, styrene, etc. Color printing toner is five poison, such as tin, a few grams per million can endanger the human body hormone secretion, serious will lead to infertility. More than a decade ago, a study published in the lancet by Spanish scientists warned that dust from electrostatic photocopiers could cause lung disease. Soon afterwards, ERA, a us environmental research organisation, came to a similar conclusion. Back in 2003, Germany's Dortmund department of labor and medical protection conducted a trial in which rats were exposed to carbon dust. Similarly, the institute for Labour protection in Bonn conducted similar experiments on mice and guinea pigs, but found no abnormalities. Both experiments, however, found an inflammatory response when animals inhaled tiny particles released by the device. Unfortunately, until now, the instructions for these devices have not included any warning of harmful substances in the toner. In fact, carbon powder particles are harmful to the human body, because carbon powder particles are very small, it is easy to be suspended in the air, through the respiratory tract into the human body, and carbon powder in the human body can not be melted, excretion is very difficult. After being inhaled by the human body, it is difficult for the carbon powder particles to be excreted through metabolism. Harmful substances will even go deep into the lungs, damaging the lung tissue, which is more harmful than second-hand smoke. Because this is long-term inspiratory or one-time inspiratory a lot of, appear very easily respiratory tract disease, insomnia, have a headache, giddy wait for perplexity, more serious it is to may cause the serious disease such as silicosis or the cancer that does not have cure. On the other hand, printing machinery will also harm the environment. They work because of high voltage electrostatic field and produce a large number of benzopyrene, dimethyl nitrosamine and other organic waste gas, these organic gases are pathogenic, teratogenic, carcinogenic substances. A recent study by researchers at the British allergy foundation also found that office equipment also emits ozone, which, while reducing the risk of solar radiation, can be harmful at high concentrations. Keep your printer away from you when you print, and keep your office printer in a special room to create a healthy office environment. |
