“…Large‐scale surveys of indoor materials that would influence stocks and flows of sorbed water have not been undertaken. Svennberg and Wadsö 48 reported the relative abundance of “surface materials exposed in dwellings” based on an inventory of 16 rooms in Swedish apartments. The resulting apportionment was 33% wallpaper, 21% painted surface, 18% textile furnishings, 15% wood, 8% synthetic flooring, and 4% textile carpets.…”

“…Two surveys of indoor surface materials important for moisture uptake and humidity buffering were mentioned in Section 2.4 33,48 . In addition to surface‐to‐volume ratios, Hodgson et al 23 and Manuja et al 25 cataloged the different materials that constituted the surfaces in their surveyed environments.…”

“…Two surveys of indoor surface materials important for moisture uptake and humidity buffering were mentioned in Section 2.4. 33,48 In addition to surface-to-volume ratios, Hodgson et al 23 surfaces (42 ± 14% of total surface area), chiefly walls, and ceilings, followed by stained wood (22 ± 12% of total surface area). Fabric/ fiber surfaces were abundant in bedrooms; plastic and metal surfaces were abundant in offices and kitchens.…”

Numerous acids and bases influence indoor air quality. The most abundant of these species are CO2 (acidic) and NH3 (basic), both emitted by building occupants. Other prominent inorganic acids are HNO3, HONO, SO2, H2SO4, HCl, and HOCl. Prominent organic acids include formic, acetic, and lactic; nicotine is a noteworthy organic base. Sources of N‐, S‐, and Cl‐containing acids can include ventilation from outdoors, indoor combustion, consumer product use, and chemical reactions. Organic acids are commonly more abundant indoors than outdoors, with indoor sources including occupants, wood, and cooking. Beyond NH3 and nicotine, other noteworthy bases include inorganic and organic amines. Acids and bases partition indoors among the gas‐phase, airborne particles, bulk water, and surfaces; relevant thermodynamic parameters governing the partitioning are the acid‐dissociation constant (Ka), Henry's law constant (KH), and the octanol‐air partition coefficient (Koa). Condensed‐phase water strongly influences the fate of indoor acids and bases and is also a medium for chemical interactions. Indoor surfaces can be large reservoirs of acids and bases. This extensive review of the state of knowledge establishes a foundation for future inquiry to better understand how acids and bases influence the suitability of indoor environments for occupants, cultural artifacts, and sensitive equipment.

Sodium dodecyl sulphate (SDS), a commonly used laundry surfactant, has been known to cause some damage to epithelial cells in skin. Further, independent experiments have shown that a single laundry wash with rinsing leaves a residue of around 10% of the chemicals used in a wash cycle. A realistic nonlinear system of partial differential equations is developed for coupled water and solute transport through a drying porous medium when the solute has a mobile state (monomers) as well as an immobile state (micelles). An accurate finite difference scheme is developed and tested against known exact solutions of the nonlinear porous medium equation for transport of water and against known conservation laws. It shows that at the end of atmosphere-controlled stage 1 of drying when little water remains, the concentration of SDS near the drying surface, where it may contact skin, is commonly an order of magnitude higher than its initial value. The problem is exacerbated by successive regular wash cycles and by higher evaporation rates in electronic dryers. The numerical solutions show the partitioning between the two phases of SDS.
