During HOMEChem, which was a comprehensive indoor chemistry study occurring in a test house during June 2018, the real-time concentration of ammonia indoors was measured using cavity ring-down spectroscopy. Because of ammonia’s high reactivity, solubility in water, and tendency to sorb to a variety of surfaces, it is difficult to measure, and thus a comprehensive evaluation of indoor ammonia concentrations remains an understudied topic. Indoor ammonia is strongly emitted from cleaning products, tobacco smoke, building materials, and humans. Although ammonia (NH 3) is usually found at outdoor concentrations of 1–5 ppb, indoor ammonia concentrations can be much higher.
