Advances in atmospheric chemistry for applications in exposure, epidemiology, and indoor air research

摘要

Background: The application of the state-of-the-art technologies and methodologies in the Atmospheric Chemistry field can facilitate the advancement in exposure science, epidemiology, and indoor air research. Aim: The objectives of this presentation are to (1) showcase advanced technologies and methodologies from the Atmospheric Chemistry Community and their application in exposure science, epidemiology, and indoor air research, and (2) to facilitate multidiscipiinary dialogues. This presentation will introduce novel tools that can be applied across scales from personal to community levels or from regional to global levels. The technologies/methodologies introduced cover both observational approaches and modelling techniques. Recent developments of light-weight versatile sensors, instrumentation (e.g., the Aerosol Mass Spectrometer) allowing differentiating exposure of freshly emitted aerosols, and remote sensing observations and analyses will be explained. Moreover, the enhanced computer capability worldwide increases the potential of applying sophisticated atmospheric chemistry models with better transport and transformation mechanisms of pollutants than those currently used in health-related research. These models span from local to global scales capturing the finer spatial resolution of pollutant variability critical to exposure and epidemiological studies. These models which will be introduced can be used to estimate more accurate exposure levels in cross-sectional, retrospective, and prospective epidemiological studies. Challenging research questions in exposure science, epidemiology, and indoor air research can be targeted by applying these technologies or collaborating with atmospheric chemists to advance knowledge in human exposure, health impacts, indoor air quality researches.
