TLDR
In this paper, a methodology for measuring the surface charge density on printed paper and the ion and charged particle emissions during operation of a high-emitting laser printer is described, and the emission rates of ultrafine particles, ions and charged particles may be quantified using a controlled experiment within a closed chamber.Abstract:
While the emission rate of ultrafine particles has been measured and quantified, there is very little information on the emission rates of ions and charged particles from laser printers. This paper describes a methodology that can be adopted for measuring the surface charge density on printed paper and the ion and charged particle emissions during operation of a high-emitting laser printer and shows how emission rates of ultrafine particles, ions and charged particles may be quantified using a controlled experiment within a closed chamber.read more

Nanoparticle exposures from nano-enabled toner-based printing equipment and human health: state of science and future research needs
TL;DR: A methodical risk assessment based on “real world” exposures rather than on the toner particles alone needs to be performed to provide the much-needed data to establish regulatory guidelines protective of individuals exposed to TPE emissions at both the occupational and consumer level.

Assessment of fine particles released during paper printing and shredding processes
TL;DR: It was found that the printing process caused substantial release of particles with sizes of less than 300 nm in the form of metal granules and graphite, which did not elicit cytotoxicity to simian virus-transformed bronchial epithelial cells (BEAS2B) and immortalized normal human bronchials cells (HBE1).

TL;DR: Fine particulate and sulfur oxide--related pollution were associated with all-cause, lung cancer, and cardiopulmonary mortality and long-term exposure to combustion-related fine particulate air pollution is an important environmental risk factor for cardiopULmonary and lung cancer mortality.

Respiratory effects are associated with the number of ultrafine particles.
TL;DR: The present study suggests that the size distribution of ambient particles helps to elucidate the properties of ambient aerosols responsible for health effects.

Deposition of charged particles in the human airways
TL;DR: In this paper, the electrostatic charge carried by aerosol particles greatly enhances their deposition in the airways, which is due to image forces between wall and particle, and is not detectable below a charge number n 3 which depends on particle size but not on the volunteer.

TL;DR: Experimental evidence is presented that indicates that intense bursts of particles are associated with temperature fluctuations and it is suggested that the difference between high and low emitters lies in the speed and sophistication of the temperature control.
