摘要: A complete vapor intrusion (VI) model, describing entry of volatile organic chemicals (VOCs) into buildings located on contaminated sites, generally consists two main parts: one part transport in the soil and other its building. Modeling involves either analytically or numerically solving equations advection diffusion subsurface. Contaminant biodegradation must often also be included this simulation, can increase difficulty obtaining a solution, especially when explicitly considering coupled oxygen consumption. The models contaminant building pathway are to calculations indoor air concentration, both influenced by construction operational features. description consideration foundation characteristics, while calculation levels requires characteri...
