A groundbreaking Imperial-led study is looking at indoor exposure to air pollution in more than 100 homes in West London. The WellHome study, led by Imperial College London’s world-leading Environmental Research Group, is a first-of-its-kind community-based study focusing on assessing air quality inside and outside of homes, as well as identifying various contaminants such as chemicals, biological agents, and microplastics that are present within the home environment.
