It’s best not to keep the laser printers in your company around. Laser printers are a "bigger" of environmental pollution, and the harm it brings to your body is comparable to that of cigarettes.
Professor Linda Morriswa of the Queensland University of Technology in Australia and others have found that the fine particles released by laser printers can effectively penetrate into the lungs when inhaled by the human body. Induce cardiovascular disease and even cancer.
The researchers tested 62 laser printers. The researchers placed the printers in a sealed test chamber and recorded the concentration of particles released during their work. It was found that 17 units emitted a large amount of particles, and the pollution rate was nearly 30%. In addition, although other electronic products in general offices also release dust and particles, they are not as high as printers.
The researchers also concluded that in a closed office space, the level of particles in the air is 5 times higher when the printer is working than when it is not working.
Researchers believe that it is the fine toner in printer cartridges that releases harmful particles, not inks and other substances. In addition, the degree of release of particles is related to the type of printer, the degree of newness, the type of ink cartridge, and the service life of the printer, and it cannot be generalized.
