“…11 In addition to sorption effect, subsequent desorption of nicotine from indoor surfaces to air has been shown to contribute to secondhand exposure. 12 Additional research is needed to investigate the effects of other indoor sorbents, such as fabrics, wallboard paper, and clothing on sorption and desorption of nicotine aerosol exhaled by e-cigarette users. Some variations could also be due to other factors such as cleaning, room volume, and ventilation.…”

“…This proximity can result in higher personal exposures than would be estimated from pollutant concentrations measured in well-mixed building air (McBride et al 1999). Besides, even low levels of ozone emitted by printers and copier machines can combine with other commonly present indoor VOCs, triggering the formation of harmful secondary pollutants and ultrafine aerosol particles (Destaillats et al, 2006a;Singer et al, 2006;Destaillats et al, 2006b). commercial office equipment or their use in connection with the material reported herein is not to be construed as actual or implied endorsement of such products.…”

There is concern that potentially harmful pollutants may be emitted from office equipment. Although office equipment has been a focal point for governmental efforts to promote energy efficiency through programs such as the US EPA's Energy Star, little is known about the relationship between office equipment use and indoor air quality, and information on pollutant emissions is sparse. In this review, we summarize available information on emission rates and/or ambient concentrations of various pollutants that are related to office equipment use. Experimental methods used in the characterization of emissions are briefly described. The office equipment evaluated in this review includes computers (desktops and notebooks), printers (laser, ink-jet and all-in-one machines) and photocopy machines. Reported emission rates of the following pollutant groups are summarized: volatile organic chemicals (VOCs), ozone, particulate matter and several semivolatile organic chemicals (SVOCs). The latter include phthalate esters, brominated flame retardants, organophosphate flame retardants and polycyclic aromatic hydrocarbons (PAHs). We also review studies reporting airborne concentrations in indoor environments where office equipment was present and thought to be a significant contributor to the total pollutant burden (offices, residences, schools, electronics recycling plants). For certain pollutants, such as organophosphate flame retardants, the link between emission by office equipment and indoor air concentrations is relatively well established. However, indoor VOCs, ozone, PAHs and phthalate esters can originate from a variety of sources, and their source apportionment is less straightforward. This literature review identifies substances of toxicological significance, with the purpose of serving as a guide to evaluate their potential importance with respect to human exposures. Submitted to Atmos. Environ. IntroductionThe last few decades have seen major changes in the work environment. , 2001). In addition, the use of notebook computers spanning both work and non-work environments is on the rise.There is concern that potentially harmful pollutants may be emitted from office equipment. As summarized below, office equipment has been found to be a source of ozone, particles, volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs). Among the chemicals emitted by office equipment are VOCs and SVOCs that have been associated with occupational symptoms such as eye, nose or throat irritation, headache and fatigue (Mendell et al. 2002;Wolkoff et al. 2006).The widespread and growing use of office equipment by a large fraction of the population in their workplaces, homes, and schools and the incomplete and fragmented evidence of this equipment as a source of health-relevant indoor air pollutants provide compelling arguments for a systematic evaluation of pollutant emissions. Since distributed desktop computers and associated displays are in close proximity to people, research on pollutant emissions from off...

“…Nicotine's reaction with ozone forms cotinine, formaldehyde, n-methyl-formamide, and nicotinaldehyde 65 . In a controlled setting that used a chamber to simulate a real environment, the presence of O 3 did not lead to the reemission of nicotine to the gaseous phase, but to products of nicotine's oxidation (N-methylformamide and miosmine).…”
