Propagation and Diffusion of Fluorescent Substances with Footprints in Indoor Environments.

ABSTRACT: Some studies have shown that contaminants can be transferred between floors and the soles, and there are few studies on pollutant propagation caused by human walking in real-life situations. This study explored the propagation and diffusion law of ground pollutants from rubber soles to poly vinyl chloride (PVC) floor during indoor walking through employing a fluorescent solution as a simulant. The footprint decay (D) and transfer efficiency (τ) of the fluorescent solution transferred from the sole to the indoor floor during walking were analyzed based on the fluorescent footprint imaging. The effects of namely body weight (50-75 kg), walking frequency (80-120 steps/min), and solution viscosity (oil and water) were also investigated. It was found that the total fluorescence gr
