“…Water-solubility is important as some metal ions (e.g., Zn 2+ ) impart toxicity via ion leaching and may play a role in the initiation of oxidative DNA damage and reactive oxygen species (ROS) formation [29,30]. Our findings are in good agreement with the chamber study of Pirela et al, and others [31][32][33].…”

“…Therefore, it is believed that the unusual high indoor concentration was transported from indoors. This assumption is supported by the fact that the door was open on 04/06/2014 until 13:00, along with the absence of any hardcopy devices inside the office, which are strongly related to ultrafine particle emissions [17,18,23,53]. In addition, PM 10 mass concentration was affected by indoor and outdoor sources (Fig.…”

Printing speed, type of toner, number of printing pages, coverage of the paper [17,24,25] are factors strongly associated with emissions from printers. These characteristics make hardcopy devices a major pollutant for the indoor environment influencing further human exposure.…”

a b s t r a c tIndoor/Outdoor (I/O) particulate mass concentration (PM 10 ) and number concentrations were measured online in modern office environments with mechanical ventilation. The measurement took place during June 2014 in a building, which, belongs to the Norwegian Institute for Air Research, in Norway. Particle number size distribution was measured with an SMPS (0.014e0.7 mm) and an APS (0.5e18 mm) instruments, whereas, mass concentration was measured with a Dust-Trak II photometer. Two offices were selected to examine the outdoor contribution of particles and the influence of indoor sources. One office was fully occupied during working hours and the second one unoccupied at all times. The results suggested that human presence during the working hours affected considerably indoor particles in the occupied office both in terms of number and mass concentration compared to the non-working hours conditions. In the absence of any significant indoor source generating new particles (hardcopy devices), the indoor environment was influenced mainly from the presence of people with resuspension activities being the most important source for particle sizes larger than 1 mm. Moreover, indoor particle number and mass concentration was influenced substantially from outdoor sources. Generally, both indoor number and mass concentrations showed temporal fluctuations similar to those observed outdoors, suggesting that particle penetration was significant in both offices. However, low I/O ratio (90 th percentile < 0.3 for both offices) indicated the efficient removal of particles from the air filtration system.

“…Arising from surface charge, the electrostatic force leads to transport of radioactivity far from radioactive sources and accumulation of contamination on soil and plant surfaces [6]. Electrical household appliances are a significant source of ultrafine charged particles, which affect indoor air quality [7][8][9][10][11]. Electrostatic interactions may prevent the aggregation of charged aerosol particles and allow them to carry various air pollutants including microorganisms, dust, and sometimes radon progeny to long distances [6].…”

“…It was found that the electrostatic force arising from the surface potential of 198 Au contributes to the total adhesive force. In addition to radioactive particles, there are many examples in which the electrostatic force plays a critical role because aerosol particles can naturally or artificially acquire surface charge [6,7,12].…”
