Because humans spend about one-third of their time asleep in bedrooms and are themselves emission sources volatile organic compounds (VOCs), it is important to specifically characterize the composition bedroom air that they experience during sleep. This work uses real-time indoor outdoor measurements (VOCs) examine concentration enhancements sleep calculate VOC rates associated with sleeping occupants. Gaseous VOCs were measured proton-transfer reaction time-of-flight mass spectrometry a...
In the United States, PM2.5 and NOx pollution disproportionately burden communities of color lower income. However, such information is lacking when it comes to hazardous air pollutants (HAPs) like toxic volatile organic compounds, for which city-wide measurements are more challenging thus not available in routine observations.In this study, we use highest spatially resolved (~2 km) airborne emissions concentrations ever reported HAPs while covering a whole megacity, combine these...
In Los Angeles, air pollution disproportionately impacts communities of color and low-income residents. Routine city-wide measurements hazardous pollutants (HAPs), concern for health contributing to urban pollution, are notably lacking. this study, we use the highest spatially resolved (∼2 km) emissions concentrations ever reported HAPs while covering a whole megacity combine observations with US Census information. We observe higher 17 measured HAPs, such as benzene, naphthalene,...
The chemical composition of incense-generated organic aerosol in residential indoor air has received limited attention Western literature. In this study, we conducted incense burning experiments a single-family California residence during vacancy. We report the fine particulate matter (PM
