“…It was also shown that the VOC emissions from wood-based materials can be decreased by up to 90% through the application of marketed coatings [79]. The latex paint test results showed a maximum barrier effect for formaldehyde, whereas a minor barrier effect for acetaldehyde was recorded [80,81].…”

Volatile organic compounds (VOCs) are the main source influencing the overall air quality of an environment. It is a well-known fact that coated furniture units, in the form of paints and varnishes, emit VOCs, reducing the air quality and resulting in significant health problems. Exposure time to such compounds is also an important parameter regarding their possible health effects. Such issues also have a greater influence when the exposure period is extended. The main objective of this study was to review some of the important factors for the emission of VOCs from coated furniture, from the perspective of material characteristics, as well as health concerns. Some methods for controlling VOC emissions to improve indoor air quality, from the point of view recent regulations and suggestions, are also presented in this work.

“…We adopted the empirical value of B 1 and its uncertainty (1.6 ± 0.5 × 10 4 K) for China V standard light-duty gasoline car, which accounted for 87% 36 of the total number of vehicles in China in 2015. 32 For evaporative emissions from solvent use, we applied the experimental value of B 2 (4.9 ± 1.0 × 10 3 K) for formaldehyde, 37 whose emission from building materials had a temperature dependency similar to that of other common solvents. 38 A 3 (0.1 ± 0.01 kg m –2 s –1 K –1 ) and B 3 (26.6 ± 4.0 kg m –2 s –1 ) and their uncertainty ranges were fitted from Song et al 14 based on measurements in a Northern Chinese city in 2017.…”

The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence of evaporative AVOC fluxes in a regional air quality model and evaluated the impacts on surface ozone in the Beijing−Tianjin−Hebei (BTH) area of China during the summer of 2017. The temperature dependency of AVOC emissions drove an enhanced simulated ozone-temperature sensitivity of 1.0 to 1.8 μg m −3 K −1 , comparable to the simulated ozone-temperature sensitivity driven by the temperature dependency of biogenic VOC emissions (1.7 to 2.4 μg m −3 K −1 ). Ozone enhancements driven by temperature-induced AVOC increases were localized to their point of emission and were relatively more important in urban areas than in rural regions. The inclusion of the temperature-dependent AVOC emissions in our model improved the simulated ozone-temperature sensitivities on days of ozone exceedance. Our results demonstrated the importance of temperature-dependent AVOC emissions on surface ozone pollution and its heretofore unrepresented role in air pollution−meteorology interactions.
