Abstract
The effects of outdoor air pollution on the human body, including cardiovascular and respiratory complications, is well-documented. Recently, more attention has been brought to concerns about indoor air quality and our knowledge gaps in this field. Indoor air quality is important as humans in developed countries spend a majority of their time indoors, especially in colder climates such as the subarctic. During the Alaskan Layered Pollution and Chemical Analysis (ALPACA) field campaign in Fairbanks, Alaska conducted from January to February 2022, indoor air quality was investigated through detailed chemical characterization of indoor aerosols. Using an aerosol time-of-flight mass spectrometer (ATOFMS), the real-time size and chemical composition of individual aerosol particles were measured. Additionally, a scanning mobility particle sizer (SMPS) and an aerodynamic particle sizer (APS) measured aerosol size distributions. The chemical composition of indoor aerosols, including those resulting from indoor cooking, pellet stove, and incense burning experiments, were explored in this work. From this data, we will better be able to understand the sources and chemical composition of individual indoor aerosols.
