Human Ammonia Emission Rates under Various Indoor Environmental Conditions

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(9), P. 5419 - 5428

Published: April 1, 2020

Ammonia (NH3) is typically present at higher concentrations in indoor air (∼10-70 ppb) than outdoor (∼50 ppt to 5 ppb). It the dominant neutralizer of acidic species environments, strongly influencing partitioning gaseous and basic aerosols, surface films, bulk water. We have measured NH3 emissions from humans an environmentally controlled chamber. A series experiments, each with four volunteers, quantified as a function temperature (25.1-32.6 °C), clothing (long-sleeved shirts/pants or T-shirts/shorts), age (teenagers, adults, seniors), relative humidity (low high), ozone (<2 ppb ∼35 Higher more skin exposure (T-shirts/shorts) significantly increased emission rates. For adults seniors (long clothing), are estimated be 0.4 mg h-1 person-1 25 °C, 0.8 27 1.4 29 based on relationship observed this study. Human sufficient neutralize acidifying impacts human CO2 emissions. Results study can used accurately model inner-city associated chemistry.

Wearable Sensors and the Assessment of Frailty among Vulnerable Older Adults: An Observational Cohort Study

Sensors, Journal Year: 2018, Volume and Issue: 18(5), P. 1336 - 1336

Published: April 26, 2018

Background: The geriatric syndrome of frailty is one the greatest challenges facing U.S. aging population. Frailty in older adults associated with higher adverse outcomes, such as mortality and hospitalization. Identifying precise early indicators pre-frailty measures specific components are key importance to enable targeted interventions remediation. We hypothesize that sensor-derived parameters, measured by a pendant accelerometer device home setting, sensitive identifying pre-frailty. Methods: Using Fried phenotype criteria, 153 community-dwelling, ambulatory were classified pre-frail (51%), frail (22%), or non-frail (27%). A sensor was used monitor at physical activity, using chest acceleration over 48 h. An algorithm developed quantify activity pattern (PAP), behavior (PAB), sleep quality parameters. Statistically significant parameters selected discriminate from adults. Results: stepping walking PAB (sedentary moderate-to-vigorous activity), combined reached area under curve 0.87, 0.85, 0.88, respectively, for No discriminated rest Conclusions: This study demonstrates can identify via daily monitoring. These findings may open new opportunities order remotely measure track telehealth technologies.

Associations between indoor relative humidity and global COVID-19 outcomes

Journal of The Royal Society Interface, Journal Year: 2022, Volume and Issue: 19(196)

Published: Nov. 1, 2022

Globally, the spread and severity of COVID-19 have been distinctly non-uniform. Seasonality was suggested as a contributor to regional variability, but relationship between weather remains unclear focus attention has on outdoor conditions. Because humans spend most their time indoors because transmission occurs indoors, we here, instead, investigate hypothesis that indoor climate—particularly relative humidity (RH)—may be more relevant modulator outbreaks. To study this association, combined population-based statistics meteorological measurements from 121 countries. We rigorously processed epidemiological data reduce bias, then developed experimentally validated computational workflow estimate conditions based standard comfort Our comprehensive analysis shows robust systematic relationships outbreaks RH. In particular, found intermediate RH (40–60%) robustly associated with better outbreak outcomes (versus < 40% or >60%). Together, these results suggest conditions, particularly RH, modulate

Indoor environmental quality in offices and risk of health and productivity complaints at work: A literature review

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100314 - 100314

Published: May 1, 2023

Many service jobs are carried out in modern offices, with individual offices being increasingly replaced by open-plan settings. The high number of adult people working office buildings, most situations sharing the workplace many others during a considerable part their daily time, highlights importance providing adequate guidance to ensure quality environments. This paper aims summarize existing data on offices' indoor environmental (IEQ) conditions terms air pollution (volatile organic compounds (VOC), particulate matter and inorganic pollutants), thermal comfort, lighting acoustics respective associations health productivity-related outcomes workers. Evidence shows that although present acceptable IEQ, some settings can have levels pollutants, hygrothermal conditions/thermal comfort illuminance do not comply international standards recommendations. In addition, findings suggest existence significant between assessed IEQ indicators risk detrimental effects productivity particular, airborne particles, CO2, O3 were linked prevalence sick building syndrome symptoms.

Overall, evidence revised this work suggests promoting recommendations managers include actions that: i) all relevant periodically controlled recommended limit values; ii) declared sources avoided; iii) ventilation acclimatization strategies implemented; iv) there is possibility conduct personalized adjustments (following workers' preferences).
