Abstract

This paper challenges the traditional assumption of well-mixed indoor air constituents by integrating advanced model simulations and extensive measurements of bleach cleaning. It reveals that inorganic chlorinated products like hypochlorous acid and chloramines exhibit spatial and vertical concentration gradients, with short-lived OH radicals confined to sunlit areas. These spatial and temporal scales are modulated by chemical reactions, surface interactions, and ventilation, offering crucial insights for assessing human exposure to hazardous pollutants and the transport of indoor chemicals outdoors.
