The Indoor Chemical Human Emissions and Reactivity Project (ICHEAR): Methods

Here we present the new project “Indoor Chemical Human Emissions and Reactivity” (ICHEAR), which is focused on examining the role of human emissions on indoor air chemistry. The specific goal of this project is to investigate the impact of exhaled and dermally emitted human bioeffluents on the chemical compounds present in indoor air, their chemical transformations and total OH reactivity (overall loss rate of OH radical) under different conditions comprising a variety of factors (temperature, relative humidity, ozone, clothing level, age of human participants). The measurements were conducted in stainless steel climate chambers at the Technical University of Denmark (DTU) using state-of-the-art instruments from the Max Planck Institute for Chemistry (MPIC), the Swedish Environmental Research Institute (IVL), and École Polytechnique Fédérale de Lausanne (EPFL). During April-May 2019, groups of four persons (two males and two females) occupied the chamber daily and their emissions were quantified. This poster describes the chambers, instrumentation and the overall experimental approach used in ICHEAR.
