“…For long-term exposure, Effects Screening Levels (calculated so that lower ambient levels are unlikely to be of concern for health and the environment) are set to 3.3 μg/m 3 from the Texas Air Monitoring Information System (USA -Texas Commission on Environmental Quality, https://www.tceq. texas.gov/ accessed 11 March 2020) (Santana et al 2017). However, formaldehyde concentrations in our study were above 0.8 μg/m 3 , the benchmark set by the US Environmental Protection Agency for a 1 in 100,000 lifetime cancer risk for inhaled exposures (https://cfpub.epa.gov/ accessed 12 March 2020).…”

“…The working principle of passive sampling is uptake of gaseous pollutants from the air by an adsorbing material at a constant uptake rate controlled by diffusion, followed by desorption and titration (Buczynska et al 2009;Yu et al 2008). As opposed to continuous monitors, passive samplers are cheap and easy to use since they do not require forced air movement through the device and thus a pump operated using electricity (Santana et al 2017). However, diffusion rates can vary largely according to environmental conditions thus affecting their performance (Mason et al 2011).…”

Chipboard production is a source of ambient air pollution. We assessed the spatial variability of outdoor pollutants and residential exposure of children living in proximity to the largest chipboard industry in Italy and evaluated the reliability of exposure estimates obtained from a number of available models. We obtained passive sampling data on NO2 and formaldehyde collected by the Environmental Protection Agency of Lombardy region at 25 sites in the municipality of Viadana during 10 weeks (2017–2018) and compared NO2 measurements with average weekly concentrations from continuous monitors. We compared interpolated NO2 and formaldehyde surfaces with previous maps for 2010. We assessed the relationship between residential proximity to the industry and pollutant exposures assigned using these maps, as well as other available countrywide/continental models based on routine data on NO2, PM10, and PM2.5. The correlation between NO2 concentrations from continuous and passive sampling was high (Pearson’s r = 0.89), although passive sampling underestimated NO2 especially during winter. For both 2010 and 2017–2018, we observed higher NO2 and formaldehyde concentrations in the south of Viadana, with hot-spots in proximity to the industry. PM10 and PM2.5 exposures were higher for children at < 1 km compared to the children living at > 3.5 km to the industry, whereas NO2 exposure was higher at 1–1.7 km to the industry. Road and population densities were also higher close to the industry. Findings from a variety of exposure models suggest that children living in proximity to the chipboard industry in Viadana are more exposed to air pollution and that exposure gradients are relatively stable over time.

“…There are no ambient air quality standards for aldehydes, and studies on the health effects of outdoor formaldehyde are still few (Dahlgren et al 2003;Marcon et al 2014;Morello-Frosch et al 2000). For long-term exposure, Effects Screening Levels (calculated so that lower ambient levels are unlikely to be of concern for health and the environment) are set to 3.3 µg/m 3 from the Texas Air Monitoring Information System (USA -Texas Commission on Environmental Quality, https://www.tceq.texas.gov/ accessed 11 March 2020) (Santana et al 2017).

Chipboard production is a source of ambient air pollution. We assessed the spatial variability of outdoor pollutants and residential exposure of children living in proximity to the largest industry for chipboard production in Italy, aiming at evaluating the reliability of exposure estimates obtained from passive sampling for an ongoing epidemiological study. We obtained data on NO2 and formaldehyde, collected by the environmental protection agency of Lombardia region, at 25 passive sampling sites in the municipality of Viadana during 10 weeks (2017-18), and compared NO2 measurements with average weekly concentrations from continuous monitors. We compared interpolated surfaces of NO2 and formaldehyde for 2017-18 with previous maps for 2010. We assessed the relationship between residential proximity to the industry and pollutant exposures, assigned both using our maps and available countrywide/continental models based on routine monitoring data on NO2, PM10, and PM2.5. The correlation between weekly NO2 concentrations from a continuous monitor and a co-located passive sampler was high (Pearson's r = 0.89), although passive sampling underestimated NO2 during the cold season. For both 2010 and 2017-18, we observed higher NO2 and formaldehyde concentrations in the southern part of Viadana, with hot-spots in proximity to the industry. PM10 and PM2.5 exposures were higher for children at <1km to the industry and NO2 exposure was higher at 1-1.7 km, compared to the children living at >3.5 km. The density of roads and population was also higher in proximity to the industry. Findings from a variety of exposure models suggest that children living in proximity to the chipboard industry in Viadana are more exposed to air pollution and that exposure gradients are relatively stable over time.

“…In particular, they can be formed as a product of incomplete wood combustion in fireplaces and woodstoves, pulp and paper factories, internal combustion engines and turbines, and vehicle exhaust fumes [6]. Formaldehyde (HCHO) and acetaldehyde (CH 3 CHO) are considered two of the most important aldehydes [7,8]. They are known as carcinogenic and probably carcinogenic agents, respectively [9,10].…”

Volatile organic compounds (VOCs) are among the most abundant air pollutants. Their high concentrations can adversely affect the human body, and therefore, early detection of VOCs is of outmost importance. Among the different VOCs, in this review paper we have focused our attention to the monitoring of acetaldehyde by chemiresistive gas sensors fabricated from nanostructured semiconducting metal oxides. These sensors can not only provide a high sensing signal for detection of acetaldehyde but also high thermal and mechanical stability along with a low price. This review paper is divided into three major sections. First, we will introduce acetaldehyde as an important VOC and the importance of its detection. Then, the fundamentals of chemiresistive gas sensors will be briefly presented, and in the last section, a survey of the literature on acetaldehyde gas sensors will be presented. The working mechanism of acetaldehyde sensors, their structures, and configurations are reviewed. Finally, the future development outlook and potential applications are discussed, giving a complete panoramic view for researchers working and interested in acetaldehyde detection for different purposes in many fundamental and applicative fields.
