Assessment of indoor air quality and risk of COVID-19 infection in Spanish secondary school and university classrooms

“…Moreover, the students' movement could lead to the re-suspension of settled particles and could affect indoor PM levels through personal clouds [ [108] , [109] , [110] , [111] ]. Furthermore, the use of ethanol-based disinfectant sprays generates inhalable coarse particles (PM 2.5-10 ) [ 112 ]. In the SS classrooms, a sanitizer spray was used by the teachers, especially in SS1, to disinfectant the furniture.…”

High time‐resolution measurements of ultrafine and fine woodsmoke aerosol number and surface area concentrations in biomass burning kitchens: A case study in Western Kenya

“…The range in indoor PN (10 3 to >10 6 /cm 3 ) and PSA (10 2 –10 5 μm 2 /cm 3 ) concentrations can inform the suitability of field sampling strategies for monitoring woodsmoke aerosol size distributions via electrical mobility and aerodynamic size classification techniques. PN and PSA size distributions can be coupled with deposition fractions for the human respiratory tract to estimate inhaled deposited dose rates 113–116 …”

“…Though the common ways of deciding original and improved stove tiers based on mass metrics, such as PM 1 , PM 2.5 , elemental carbon, and brown carbon, are highly systematic and widely effective for comparing cooking environments with the same stove types, 25 it is clear that cookstoves with improved combustion such as rocket, gasifier, and air injection have the potential to release a greater abundance of particles smaller than 30 nm relative to TSFs (exemplified in distributions can be coupled with deposition fractions for the human respiratory tract to estimate inhaled deposited dose rates. [113][114][115][116] The field measurements in the Nandi kitchens can guide the development and application of low-cost aerosol sensing technologies for deployment in biomass burning environments. There has been significant research on the design, assessment, and use of low-cost optical particle counters, however, such sensors cannot reliably detect sub-300 nm particles.…”

Surface-Modified Wrinkled Mesoporous Nanosilica as an Effective Adsorbent for Benzene, Toluene, Ethylbenzene, and Xylene in Indoor Air

“…In addition, PM 2.5 can induce climate changes, and the inhalation of PM 2.5 can cause various health problems in humans. Therefore, volatile organic compounds (VOCs), which are precursors of PM 2.5 that are toxic to humans, have been classified as the most serious air pollutants; furthermore, the development of technologies to capture these pollutants is in high demand. − …”
