If you’re like the typical human, you likely spend about 90% of your time inside. Our homes, businesses, exercise facilities, cars, and gathering places are all examples of indoor environments where we’re constantly breathing the air. Therefore, it is crucial to understand the chemistry occurring in these spaces and what it means to our health and well-being.
Among the many sources of pollution in indoor environments are human beings themselves. Emissions via breath and skin represent mobile, potent, chemically diverse and highly variable sources of reactive chemicals in indoor spaces. The project ICHEAR aims to comprehensively characterize the chemical impact of human beings, the single common element in all living spaces.
We have chosen a set of experiments that focus on the two most common everyday activities to the air chemistry of indoor environments: cooking and cleaning. These activities are (1) realistic representations of activities performed in indoor environments and (2) likely to drive interesting chemical reactions that can be better understood through this study.
