To gain a comprehensive understanding of the effects of air pollution on human health, it is imperative to assess exposure at an individual level. This necessitates the use of personal monitoring equipment that can record exposure in real-time while simultaneously capturing relevant biometric data and the activities being undertaken by the individual. The dataset presented herein encompasses data from five distinct sources, collected in Ljubljana, Slovenia: (a) Questionnaire filled out by all participants for general information, i.e., age, height, weight. (b) Time Activity Diaries maintained by participants. (a) A personal particulate matter sensing unit that recorded data on PM1, PM2.5, PM10, ambient temperature, relative humidity, and geographical location coordinates. (b) A wrist-worn Smart Activity Tracker that captures heart rate and movement data. (c) An Indoor Air Quality sensing unit, specifically the uHoo device, which measures parameters such as Temperature, Relative Humidity, CO2, TVOC, PM2.5, CO, O3, NO2, and Air Pressure. Participants were equipped with these sensors for two separate 1-week durations in 2019, specifically during a heating season and a non-heating season, as part of the ICARUS H2020 project. Throughout these periods, data was recorded at a 1-minute resolution. Additionally, based on the collected data, an inhalation rate was determined, and an inhalation adjusted exposure (or intake dose) was computed. The richness and granularity of this dataset not only offer insights into the direct health implications of air pollution exposure but also provide a valuable resource for urban planners, environmental scientists, and policymakers aiming to design healthier living environments and implement effective air quality regulations.
