“…A strong focus on atmospheric air pollution has been developed worldwide which has led to a significant reduction of some contaminants in the atmospheric environment. The starting point of this approach is that the population, especially in urban areas, spends most of the time (up to 90 %) indoors (Carrer et al, 2000;Avino et al, 2003;Kelly & Fussell, 2019).…”

The air quality monitoring is based on the determination of some gaseous pollutants and PM10 and PM 2.5 . Recent studies have reported the importance of the determination aerosol fraction below 1 µm both for the dynamic of the airborne and for the public health issue. This paper would like to investigate the importance of this fraction in the air quality monitoring. Further, a particular focus will be devoted the role of the Ultrafine Particles, i.e. particles below 100 nm, in the aerosol formation and in the human exposure. Two case studies will be presented and discussed on how the submicron particles can be determined and interpreted their role. In the first case, the measurements will be performed in downtown Rieti, city located in central Italy, 100 km North from Rome, with the scope to draw the behavior in relationship to the emission flexes. In the second scenario, the personal exposure of pedestrians will be investigated in Venafro, a small city located 150 km South-East Rome, by means of measuring PMx, total submicron fraction, different aerosol dimensional sizes in the range 5-360 nm along with the total Volatile Compounds. The different sources and contributions affecting the aerosol levels in the two areas will be investigated and extensively discussed as well as the role of the such particles in the aerosols science.

“…In addition, many studies showed a higher toxicity for cigarette smoke compared with ambient PM sources such as dust and traffic. [64][65][66] To improve indoor air quality for people especially for vulnerable groups, 67 SHS is still an important pollutant from a public health perspective. 1,20 Peak analysis developed in this study allows us to quantify the contribution of PM 2.5 from SHS exposure from specific locations and time periods.…”

Characterizing peak exposure of secondhand smoke using a real‐time PM _2.5 monitor

Although short‐duration elevated exposures (peak exposures) to pollutants may trigger adverse acute effects, epidemiological studies to understand their influence on different health effects are hampered by lack of methods for objectively identifying peaks. Secondhand smoke from cigarettes (SHS) in the residential environment can lead to peak exposures. The aim of this study was to explore whether peaks in continuous PM2.5 data can indicate SHS exposure. A total of 41 children (21 with and 20 without SHS exposure based on self‐report) from 28 families in New York City (NY, USA) were recruited. Both personal and residential continuous PM2.5 monitoring were performed for five consecutive days using MicroPEM sensors (RTI International, USA). A threshold detection method based on cumulative distribution function was developed to identify peaks. When children were home, the mean accumulated peak area (APA) for peak exposures was 297 ± 325 hour*µg/m3 for children from smoking families and six times that of the APA from non‐smoking families (~50 ± 54 hour*µg/m3). Average PM2.5 mass concentrations for SHS exposed and unexposed children were 24 ± 15 µg/m3 and 15 ± 9 µg/m3, respectively. The average SHS exposure duration represents ~5% of total exposure time, but ~13% of children's total PM2.5 exposure dose, equivalent to an additional 2.6 µg/m3 per day. This study demonstrated the feasibility of peak analysis for quantifying SHS exposure. The developed method can be adopted more widely to support epidemiology studies on impacts of short‐term exposures.

“…As pollutants from exterior sources can affect the interior air quality [22][23], the residential spaces (RS) that were investigated from the point of view of indoor air quality were selected based on the area where they are located, being selected a building located relatively far from the traffic (RS1) and a building located next to a high traffic boulevard (RS2 and RS3). Interior spaces (with drawings in fig.3) were chosen on the assumption that in the kitchen areas there are many sources of emissions and the resting area (bedroom) is the most importance space, where emissions should be minimized.…”

“…Most of the times the effects of VOCs on human health are amplified by indoor conditions such as temperature and humidity [21]. VOCs could be at the base of various discomforts inside the buildings and lead to what is called sick building syndrome (SBS) in scientific literature [4,22]. Understanding the evolution of TVOCs concentration inside buildings is the basis for predicting this variation and a correct ventilation strategy for interior spaces.…”

Indoor air quality (IAQ) remains a very important issue because it can significantly affect people’s health, comfort and productivity. Volatile organic compounds (VOCs) comprise an important group of chemicals that are commonly present in indoor air. They are related to the sick building syndrome (SBS) and exposure to VOCs is of considerable concern due to their potential chronic and acute health outcomes which includes eye irritation, nose and throat discomfort, headache, allergic skin reaction, nausea, fatigue, or dizziness. Most of the times the effects of VOCs on human health are amplified by indoor conditions such as temperature and humidity. The paper presents the findings of the analysis of the relationship between total volatile organic compounds (TVOC) concentrations and their influencing factors like indoor comfort parameters (temperature and relative humidity) and the type of indoor spaces (offices, residential and educational). Keywords: TVOC concentrations, indoor comfort parameters, Pearson correlation coefficients
