Predictive model of indoor PM_2.5 mass concentrations.

Abstract

<p>a. the levels of <i>distance to road</i>: 1- ≤ 193 m, 2–194–270 m, 3–271–425 m, 4- >425 m.</p><p>b. the levels of <i>frequency of furniture cleaning</i>: 1- everyday, 2- some times per week, 3- one time for several weeks.</p><p>c. the levels of <i>smoking</i>: 0- no smoking, 1- yes, 1time, 2- yes, multiple times.</p><p>d. the levels of <i>indoor plants</i>: 1- no plants, 2- a few, 3- many.</p><p>e. the levels of <i>frequency of floor cleaning</i>: 1- everyday, 2- some times per week.</p><p>f. the levels of <i>floor cleaning method</i>: 1- only mop, 2- with mop and broom/vacuum.</p><p>g. the levels of <i>traffic route</i>: 1-arterial road (ring roads and express ways), 2-urban highway, 3-quiet street.</p><p>Predictive model of indoor PM_2.5 mass concentrations.</p
