“…For C8-aromatics, while the mean respiratory AFs in many studies [29,46,49,50,[52][53][54] were lower than the 66.9% recorded in this study, other studies have reported much higher AFs [41,51]. Our results also indicated that the respiratory AFs of BTEX were much lower than 90%, which has been assumed to be the AF for toxic VOCs when assessing the human health risks of HAP exposure in many previous studies [6,[21][22][23][24]69].…”

“…Partly due to the difficulty in obtaining their respiratory AFs, toxic VOCs were still assumed to be totally absorbed in many studies on inhalation exposure health risk [60][61][62][63][64][65][66][67][68]. Alternatively, a number of studies have instead assumed AFs of 90% for toxic VOCs [6,[21][22][23][24][69][70][71], and very recently a few studies proposed 50% or 60% as the AFs of toxic VOCs [72,73]. Therefore, authentic respiratory AFs are important parameters to be determined for accurate assessment of human health risks by inhalation exposure of toxic VOCs.…”

“…Inhalation is a major pathway of human exposure to toxic VOCs due to their volatility [11], and respiratory exposure to toxic VOCs is associated with health risks including sensory irritation [12,13], asthma [14,15], chronic obstructive pulmonary disease (COPD) [16], cardiovascular diseases, leukemia, and other cancers [13,[17][18][19][20]. To exert an effect on internal organs, a toxicant must be absorbed; respiratory absorption factors (AFs), i.e., the percentages of inhaled toxics that are absorbed and retained inside the body, are therefore essential to estimate the chronic daily intake (CDI) and lifetime cancer risk (LCR) of the corresponding toxic VOCs [6,[21][22][23][24][25].…”

“…With regard to certain compounds such as benzene (0.04 mg/m 3 ), butyl acetate (0.09 mg/m 3 ) and ethyl benzene (0.080 mg/m 3 ), even low concentrations could produce strong odors which were easy to perceive. In traditional means, the hazardous effects were estimated only by judging their chemical concentrations [22]. However, compounds with low concentration could also be harmful, such as releasing irritate odor.…”

In studying indoor atmospheric pollution, the concentration of air pollutants is considered to be the primary factor in judging indoor pollution level, while sensory effects accessed by olfactory analysis has not been paid enough attention. In this paper, twenty living rooms in Beijing including newly decorated, 3 months and 6 months after decoration were sampled once a day for 10 d, and qualitative analysis, quantitative analysis and olfactory analysis of volatile organic compounds were carried out. The results showed the concentrations of the 6 main compounds surpassed the limitation values released by World Health Organization; the pollutants with highest chemical concentrations were not the most odor active odorants. Olfactory analysis which measured the odor characters such as odor detection threshold (ODT), odor active value (OAV) and odor quality was a helpful tool to identify possible chemicals which cause indoor smelling issues, and it was necessary to access indoor air quality in combination with their chemical concentrations to give a comprehensive judgment on indoor air quality.

“…Some studies indicate that many volatile organic compounds (VOCs) [6] [7], formaldehyde and ozone are emitted during the operation of photocopiers and laser printers, compromising the indoor air quality. The quality and quantity of substances emitted are determined by the technical process, the type of toner and paper used by the model and age of equipment, maintenance and environmental conditions [8].…”

In recent years proof of "indoor air quality", designed to protect and improve the health and safety of workers, was a central strategy in the prevention of many companies. The man creates with the environment in which he lives and works a continuous gas exchange through breathing; this makes the respiratory system main entrance of air pollutants. The indoor pollutants are numerous and originate from different sources. Their concentration may vary over time and depends on the nature of the source, on ventilation, habits and activities carried out by the occupants in the areas concerned. It is well known that photocopiers and laser printers are equipment that emit several chemicals (ozone, solvents, toner dust) both to release the materials used for their operation (toner, ink, paper) and then to the special printing technology used. During the printing and photocopying processes occurring chemical and physical processes complex, during which the components of toner and paper will react under the influence of light and high temperatures. More recently, there have been a growing number of articles as a result of indoor air pollution. They have become more and more significant; probably because of increasing of the concentrations of harmful substances in the confined environment. Particular attention has been given to the emission of harmful substances from electronic equipment and printing that are increasingly present in living and working place. This work was the main objective the emission of volatile organic compounds, formaldehyde and ozone from laser printing devices and consequently the estimation of elimination of same substances through a paper filters which operate through a mechanism of filtration surface with interstitial and penetration of particles into matrix filter on agglomeration, they also enclose type sandwich a layer of activated carbon.
