“…The values found are consistent with the ones recorded in literature (Liaud et al 2014;Slezakova et al 2009), for PAHs, showing values between 0.50 and 290.0 ng m −3 for PM 2.5 and between 0.80 and 300.0 ng m −3 for PM 10 . Specifically, the compound levels for PM 2.5 found in this study are comparable or smaller with levels found by similar studies ranging from 0.057 to 12.7 ng m −3 for pyrene, 0.032 to 1.36 ng m −3 for benzo(k)fluoranthene, and 0.072 to 8.38 ng m −3 for benzo(a)pyrene.…”

In order to estimate air quality at work environments from small and medium-sized enterprises (SMEs), we determined both the concentration of particulate matter (PM and PM) and the presence of polycyclic aromatic hydrocarbons (PAHs), as the heavy metals in the composition of the particulate matter. Three SMEs located in the city of La Plata, Argentina, were selected: an electromechanical repair and car painting center (ERCP), a sewing work room (SWR), and a chemical analysis laboratory (CAL). The results evidenced high levels of PM exceeding the limits allowed by the USEPA and the presence of benzo(k)fluoranthene in all the analyzed sites and benzo(a)pyrene in the most contaminated site (ERCP). Regarding metals, the presence of Cd, Ni, Cu, Pb, and Mn, mainly in the fraction of PM, in the same workplace was found. As far as risk assessment at all the workplaces surveyed is concerned, risk values for contracting cancer throughout life for exposed workers (LCR) did not comply with the parameters either of USEPA or of WHO (World Health Organization).

“…In a school classroom of a low-energy building, Liaud et al (2014) reported that the indoor collected particle masses, were very limited for big particles causing large uncertainties on PM2.5 and PM10 concentrations which were often found very close to the blank values [31]. Similar behavior is observed in our study confirming the great efficiency of the filtration system implemented in the low-energy school building studied here and more generally in low-energy school buildings where efficient programmable ventilation systems are usually installed.…”

“…In this context, the particles were collected for three to four days using two three-stage cascade impactors enabled to sample PM1, PM2.5, and PM10. PAHs were then quantified according an off-line analytical method developed in a previous study [30] and already used for field measurements [31]. Contrary to the studies reported in the literature, which report single PAH measurement performed in several buildings and only on a single particle fraction, i.e., PM2.5 or PM10, this study focused on a single building to monitor its concentrations according to the time and simultaneously on several fractions of particles by means of cascade impactors.…”

The emergence of new super-insulated buildings to reduce energy consumption can lead to a degradation of the indoor air quality. While some studies were carried out to assess the air quality in these super-insulated buildings, they were usually focused on the measurement of gas phase pollutants such as carbon dioxide and volatile organic compounds. This work reports the first measurements of Polycyclic Aromatic Hydrocarbons (PAHs) associated with particles as a function of time and particle size in a low-energy building. The airborne particles were collected indoors and outdoors over three to four days of sampling using two three-stage cascade impactors allowing to sample simultaneously particles with aerodynamic diameter Dae > 10 µm, 2.5 µm < Dae < 10 µm, 1 µm < Dae < 2.5 µm, and Dae < 1 µm. The 16 US-EPA priority PAHs were then extracted and quantified by high-performance liquid chromatography (HPLC) coupled to fluorescence detection. The resulting total particle concentrations were low, in the ranges 3.73 to 9.66 and 0.60 to 8.83 µg m-3 for indoors and outdoors, respectively. Thirteen PAHs were always detected in all the samples. The total PAH concentrations varied between 290 and 415 pg m−3 depending on the particle size, the environment (indoors or outdoors) and the sampling period considered. More interestingly, the temporal variations of individual PAHs highlighted that high molecular weight PAHs were mainly associated to the finest particles and some of them exhibited similar temporal behaviors, suggesting a common emission source. The indoor-to-outdoor concentration ratios of individual PAH were usually found close to or less than 1, except during the event combining rainy conditions and limited indoor ventilation rate.

“…For example, cascade impactors were used to simultaneously sample particles of >10µm, 10-2.5µm, 2.5-1µm and <1µm in 8 different indoor locations in France. 52 When measuring compliance, it is important to consider whether a device is suitable for the levels of PM being measured; some sensors cannot detect low levels of PM whilst others cannot detect high levels of PM. For example, photometers were used to measure Pmass in highly polluted, densely populated, low income housing in urban Dhaka, Bangladesh.…”

Many populations spend ~90% of their time indoors, with household particulate matter being linked to millions of premature deaths worldwide. Particulate matter is currently measured using particle mass, particle number and particle size distribution metrics, with other metrics, such as particle surface area, likely to be of increasing importance in the future. Particulate mass is measured using gravimetric methods, tapered element oscillating microbalances and beta attenuation instruments and is best suited to use in compliance monitoring, trend analysis and high spatial resolution measurements. Particle number concentration is measured by Condensation Particle Counters, Optical Particle Counters and Diffusion Chargers. Particle number measurements are best suited to source characterization, trend analysis and ultrafine particle investigations. Particle size distributions are measured by gravimetric impactors, Scanning Mobility Particle Sizers, Aerodynamic Particle Sizers and Fast Mobility Particle Sizers. Particle size distribution measurements are most useful in source characterization and particulate matter property investigations, but most measurement options remain expensive and intrusive. However, we are on the cusp of a revolution in indoor air quality monitoring and management. Low-cost sensors have potential to facilitate personalized information about indoor air quality (IAQ), allowing citizens to reduce exposures to PM indoors and to resolve potential dichotomies between promoting healthy IAQ and energy efficient buildings. Indeed, the low cost will put this simple technology in the hands of citizens who wish to monitor their own IAQ in the home or workplace, to inform lifestyle decisions. Low-cost sensor networks also look promising as the solution to measuring spatial distributions of PM indoors, however, there are important sensor/data quality, technological and ethical barriers to address with this technology. An improved understanding of epidemiology is essential to identify which metrics correlate most with health effects, allowing indoor specific PM standards to be developed and to inform the future of experimental applications.
