Food-cooking organic aerosols (COA) are one of the primary sources submicron particulate matter in urban environments. However, there still many questions surrounding source apportionment related to instrumentation as well semivolatile partitioning because COA evolve rapidly ambient air, making more complex. Online measurements emissions from cooking different types food were performed a laboratory characterize particles and gases. Aerosol mass spectrometer (AMS) showed that relative ionization efficiency for OA was higher (1.56–3.06) typical value 1.4, concluding AMS is over-estimating suggesting previous studies likely over-estimated concentrations. spectra generated using AMS, gas particle markers identified with filter inlets gases aerosols–chemical (CIMS) be used future cooking-source studies. considerable variability both markers, dilution plays an important role budget, showing importance these caution during receptor modeling. These findings can better understand chemical composition COA, they provides useful information source-apportionment

During the first outbreak of SARS-CoV-2 pandemic population, focusing primarily on risk infection, was generally inattentive to quality indoor air. Spain, and city Madrid in particular, were among world's coronavirus hotspots. The country's entire population subject a 24/7 lockdown for 45 days. This paper describes comparative longitudinal survey air four types housing before during lockdown. analysed temperatures variations CO2, 2.5 μm particulate matter (PM2.5) total volatile organic compound (TVOC) concentrations mean daily outdoor PM2.5 concentration declined from 11.04 µg/m3 7.10 Before NO2 values scored as 'very good' 46% time, compared 90.9% that period. Although city's improved, population's exposure pollutants more acute prolonged. Due concern over domestic energy savings, lack suitable ventilation intensive use cleaning products disinfectants covid-19 crisis, pollutant levels typically higher than compatible with healthy environments. Mean rose by approximately 12% TVOC 37% 559%. also puts forward series recommendations improve environments future pandemics spells out urgent action be taken around (IAQ) event or partial quarantining protect residents respiratory ailments concomitantly enhanced susceptibility SARS-CoV-2, identified international medical research.

Given the growing interest in community air quality monitoring using low-cost sensors, 30 PurpleAir II sensors (12 outdoor and 18 indoor) were deployed partnership with members living adjacent to a major interstate freeway from December 2017- June 2019. Established assurance/quality control techniques for data processing used sensor was evaluated by calculating completeness summarizing PM2.5 measurements. To evaluate performance, correlation coefficients (r) of divergence (CoD) assess temporal spatial variability between sensors. concentrations also compared traffic levels sensors' ability detect pollution. indoor indoor/outdoor (I/O) ratios during resident-reported activities calculated compared, linear mixed-effects regression model developed quantify impacts ambient quality, microclimatic factors, human on PM2.5. In general, performed more reliably than (completeness: 73% versus 54%). All highly temporally correlated (r > 0.98) spatially homogeneous (CoD<0.06). The observed I/O consistent existing literature, explains >85% variation levels, indicating that detected various sources. Overall, this study finds community-maintained can effectively monitor PM2.5, main concerns resulting incompleteness.

Building electrification is the movement to shift building operational energy use from fossil fuels toward electricity. It has been pursued mainly reduce greenhouse gas (GHG) emissions sector. We present here ten questions concerning electrification, and attempt answer them in context of existing literature. Our span dimensions policy, life cycle impacts on environment, technological advances challenges, indoor outdoor air quality, health, economics, social-behavioral factors. find that while much extant research predicts will provide benefits terms GHG emissions, pollutant exposures, economic impacts, it remains limited a narrow set geographic regions typically fails capture full extent environmental impacts. Additionally, despite logical inferences for likely health benefits, we were unable identify explicit studies electrification. also common theme that, be successful reducing costs, adverse grid should approached parallel with increased efficiency, renewable power, smart infrastructure. Finally, people hold strong opinions about fuel options their homes, relationship between preferences complicated. To people's beliefs around government-originating communications can highlight but one must still account heterogeneous household conditions. conclude by suggesting key areas needed approach effectively equitably.
