In what quantitiessions from laser printersDo laser printers emit pathogenic toner particles into the air? Some people are convinced that they do. Thus of this issue is the subject of a public controversy. Researchers have now investigated what particles the printers really release into the air.
The results are surprising: Contrary to numerous reports, laser printers have almost no toner particles into the air. ‘But what some printers do emit are ultra – fine particles of volatile organic – chemical substances,’says WKI head of department Prof. Tunga Salthammer. ‘An important feature of these ultra-fine particles is their volatility, which means we are not looking at toner dust. Depending on So where do So where do these ultra-fine particles come from and how can explain their emergence the answer the answer, the scientists have a process to identify them and compare the quantity, size and chemical composition of the emitted particles allows developed.
