Personal Air Quality Monitors

I work on the development of a wearable Personal Air quality Monitor (PAM) that can be used to obtain accurate exposure measurements of individuals in daily life. The PAM is highly autonomous and incorporates multiple sensors for gaseous pollutants, particulate matter and other environmental stressors. High spatiotemporal resolution is achieved via an integrated GPS which allows to assess the air pollution levels of an individual in their direct environment. 


Air quality exposure studies in China

I am part of the AIRLESS1 project which aims to draw more reliable associations between personal exposure to air pollutants and adverse changes in cardiopulmonary responses and health outcomes during the heating and non-heating seasons in urban and rural settings in Beijing. Three main methodological novelties are employed in the project:

  • the detailed assessment of personal exposure to air pollution in diverse indoor and outdoor environments
  • the integration of time-activity profiles and activity-dependent inhalation rates to derive precise dose estimations
  • a comprehensive collection of medical biomarkers to understand the underlying mechanisms of health responses to air pollution exposure.

My role in the AIRLESS study is to quantify the air pollution dose of each participant with the highest accuracy possible, considering the spatiotemporal heterogeneity of air pollution and individual activity-patterns within the cohort.
