Laser printers pollute the air office, and they are no less harmful than cigarette smoking for smokers second hand. Such a conclusion was made by members of the Australian University of Technology, Cleveland.
Researchers do not even think that the printers can cause harm to people. First, their goal was to check the office ventilation. Nevertheless, the scientists were very surprised that no one can save space protection office air of dust.
The source of emissions of harmful substances in the office, as agreed at the university staff. Then they began their research. During the investigation, the experts found that on weekdays the level of pollution in the office increases 5 times more. Having all of the equipment was found that one third of the particles emitted from a laser printer toner. Most polluted printers did not yield to smokers who smoked 22-23 cigarettes daily in the workplace.
Toner particles are so small that they are able to penetrate into the body through the lungs and cause many diseases. He noticed that the printers have become more dangerous after the change cartridges. However, not all printing units are equally dangerous. Of all the printers, 60% were totally harmless, and 12% were admitted to be uncritically.
The study authors asked the Australian Government to tighten control over the manufacturers of office equipment. Such brands as Canon, HP Color LaserJet, Ricon and Toshiba participated in the research.
