Abstract Introduction Environmental pollutions are numerous and ubiquitous. Urban citizens are continuously exposed to several kind of pollutions. To assess these exposures and identify they sources, data collection at an individual level gives a more detailed picture of the multiple exposure and the microenvironments to which it is attributable [1,2,3,4]. Protocol The study combines individual measurements of exposures of 490 Brussels inhabitants, reporting on their localization and duration, and perception of health and quality of life. The protocol integrates 3 main tools: 1. Portable devices measure individual exposure during 24 hours of a normal weekday. a. Airbeam 2® measures PM1, PM2.5 and PM10 every 1sec. b. Smartphone measures noise levels every 1sec., registers GPS data and is equipped with the application Aircasting® to transfer data. c. EMDEX II® measures 50Hz electromagnetic fields every 3sec. 2. A diary reports the environments in which the participant is staying every 15min. 3. A questionnaire (standardized and based on the literature questions) focuses on socio-economic aspects, lifestyle, perception of health, and perception and knowledge of exposure. Preliminary Results Means of exposure of noise levels by microenvironments: kitchen= 51,31 (6,13) dB, living room = 46,04 (6,71) dB, dining room = 48,39 (8,00) dB, sleeping room = 28,95 (5,24) dB. Means of exposure to PM 2.5 by microenvironments: kitchen= 14,62 (49,47) µg/m3, living room= 14,68 (64,58) µg/m3, dining room = 19,51 (94,26) µg/m3. Conclusions With further analysis, the data collected will allow characterizing each type of environment reported (for ex.: living room, kitchen, park, car, biking in the city, ...) regarding their exposure to multiple pollutants combined(air, noise, low-frequency electromagnetic fields). Next to the study of the scientific literature, the results will enable target recommendations on exposure prevention, considering the potential synergies due to co-exposures. Key messages • A detailed knowledge of multiple exposures at an individual level and their sources is neccessary to tackle the issue. • Exposure to different type of pollutions impact similar systems of the human organisms and studies on their combined effects and potential synergies are relevant.
