Laser Printer and its impact on Health

In the issue of American Chemical Society’s Environmental Science & Technology Journal, some of the Laser printers release tiny particles of toner-like material (tonner can be said as a printers powdered ink) into the air and can pose a long term health hazard to people, when these are inhaled.
The report, which was based on the research conducted at the Queensland University of Technology in Brisbane, who studied the printers used in home and office found that some of these released particles of printers from the toner-an ultra thinner powder used instead of ink (as in ink jet printer)
This study investigated particle number and PM2.5 emissions from printers. The monitoring of particle characteristics in a large open office showed that particles generated by printers can significantly (p = 0.01) affect the sub micrometer particle number concentration levels in the office; these released particles were comparable to emissions released from smoking a cigarette.
This could mean that we (non-smokers) could end up with the same lung as a passive smoker does.

  1. This is the precise weblog for anybody who needs to seek out out about this topic. You notice so much its almost arduous to argue with you. You positively put a brand new spin on a subject that's been written about for years. Nice stuff, simply nice!
