Modelling consortium for chemistry of indoor environments (MOCCIE): integrating chemical processes from molecular to room scales

We report on the development of a modelling consortium for chemistry in indoor environments that connects models over a range of spatial and temporal scales, from molecular to room scales and from sub-nanosecond to days, respectively.

Residential water-soluble organic gases: chemical characterization of a substantial contributor to indoor exposures

Characterization of residential indoor air showed that organic acids make up a significant portion of water-soluble organic gases.

Distribution of five SVOCs in a model room: effect of vacuuming and air cleaning measures

We monitored the distribution of SVOCs in model rooms in dependence of temperature and cleaning measures over a period of six months.

Assessment of fine particles released during paper printing and shredding processes

In this study, we investigated the airborne particles released during paper printing and paper shredding processes in an attempt to characterize and differentiate these particles.

Human occupant contribution to secondary aerosol mass in the indoor environment

Occupancy in indoor spaces can contribute to indoor aerosol mass via reactions of oxidants such as ozone with skin constituents and subsequent partitioning of those oxidation product to existing aerosol.

Sources of isocyanic acid (HNCO) indoors: a focus on cigarette smoke

The sources and sinks of isocyanic acid (HNCO), a toxic gas, in indoor environments are largely uncharacterized.

Degradation of phthalate esters in floor dust at elevated relative humidity

Emerging investigator series: Phthalate losses in floor dust are due to abiotic chemical degradation as well as microbial degradation of phthalates under elevated relative humidity conditions.

Emerging investigator series: primary emissions, ozone reactivity, and byproduct emissions from building insulation materials

Insulation materials affect indoor air by (i) releasing primary volatile organic compounds (VOCs) from enclosure cavities to the interior space, (ii) mitigating exposure to outdoor pollutants through reactive deposition (of oxidants, e.g., ozone) or filtration in infiltration air, and (iii) generating secondary VOCs and gas-phase byproducts from chemical reactions.

About this collection

Guest Edited by ESPI Editorial Board member Delphine Farmer (Colorado State University, USA) and Nina Vance (University of Colorado at Boulder, USA), this Themed Issue showcases advances in the area of indoor air chemistry, highlighting its diverse impact in the field of environmental science. The issue covers a range of topics (e.g., surface chemistry, microbial activity, photochemistry, exposure science) from an array of approaches (e.g., instrument development, measurements, modeling, and consideration of policy and health impacts of indoor air quality). We hope you enjoy reading the papers in this collection.
