Overview
Topic status: We're looking for students to study this topic.
The emission of ultrafine particles from laser printers has been at the forefront of scientific news recently. However, what is not realized is that, at the same time, some printers also emit large quantities of electrical charge into the atmosphere.
Hypothesis/Aims
Charged particles are more likely to be deposited in the human respiratory system during inhalation than uncharged particles and, therefore, may form a potential health risk.
Approaches
In this project, you will monitor air ions and charged particles emitted by a selection of laser printers under various conditions. The aim of this study is to quantify the rate of emission in terms of printer type, temperature, print speed, toner and paper type and to investigate the source and mechanism of emission of these ions.
