Filename: 20251020_ClinicalIAQ_Willis.csv Short description: This dataset contains measurements of airborne particle concentrations and environmental conditions collected in clinical settings, including dental clinics and hospitals. Data were recorded using a GRIMM 1.109 (Grimm Technologies, Inc., Douglasville, GA, USA) aerosol spectrometer and TSI Q-Trak Indoor Air Quality (IAQ) Monitor (TSI Incorporated, Shoreview, MN, USA) (Appendix E) to assess indoor air quality and bioaerosol exposure. This dataset can be used to evaluate indoor air quality, particle exposure levels, and environmental conditions in healthcare environments. 2. Relationship between files: NA 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: GRIMM Aerosol Spectrometer: Operated during hour long samples to measure size-resolved airborne particle concentrations in real time. Q-Trak Indoor Air Quality Monitor: Used to continuously measure background environmental conditions, including carbon dioxide (CO₂), temperature, and relative humidity, throughout one-hour sampling runs to characterize indoor air quality in the clinical environments. 2. Methods for processing the data: GRIMM Aerosol Spectrometer: The instrument provided total particle counts and size-resolved particle distributions, which were exported from the GRIMM in tabular format. Q-Trak Indoor Air Quality Monitor: CO2, temperature, and relative humidity were continuously logged during sampling. Logged data were exported from the Q-Trak as a txt file and then copied in tabular format. 3. Instrument- or software-specific information needed to interpret the data: No specific software is required to interpret the submitted dataset. The data can be understood and analyzed without access to the original instrument software. Data has been reviewed and compiled so outside software is not needed. 4. Standards and calibration information, if appropriate: GRIMM Aerosol Spectrometer: Factory-calibrated by the manufacturer for particle sizing and counting. Q-Trak Indoor Air Quality Monitor: Calibrated by the manufacturer for CO, CO₂, temperature, and relative humidity measurements. 5. Environmental/experimental conditions: Data were collected in clinical environments, specifically dental clinics and hospital patient rooms. Conditions varied depending on occupancy, ventilation, and clinical activity at the time of sampling. University of Utah Dental School Student Dental Clinic: Aerosol sampling was conducted in a 6,484-square-foot open-plan dental clinic with 60 chairs, where many aerosol-generating procedures occur. University of Utah Hospital: Sampling was performed in patient rooms and hallways or nurses' stations within the acute pulmonary medicine unit and MICU. Samples were also taken in the waiting room of the Emergency Department. 6. Describe any quality-assurance procedures performed on the data: Data exported from the GRIMM and Q-Trak instruments were processed in Excel. All formulas and calculations were verified by performing them twice and double-checking for consistency to ensure correctness. 7.
