“…It seems likely that the irreversible component of uptake reflects either oxidation from S(IV) to S(VI), or the chemical binding of S(IV) to molecules in the surface materials. Supporting the importance of the oxidation pathway are these quotes: “Sulfur dioxide is sorbed by paper and slowly converted to sulphuric acid.” 170 “The sorbed SO 2 is undoubtedly converted to a large extent to sulphite and thence oxidised to sulphate.” 173 “The sorbed sulphur dioxide is oxidised to sulphur trioxide which reacts with water in the leather to produce sulphuric acid.” 174 “The conversion of S(IV)→S(VI) on both iron and zinc was found to have a half‐life of ~ 24 hours.” 177 …”

“…Although not the subject of many systematic recent investigations, studies of SO 2 interactions with indoor surface materials were widely undertaken in the 1960s and 1970s. [169][170][171][172][173][174][175][176][177][178] One exception to the historical pattern is the more recent work by Grøntoft and Raychaudhuri, 179 who assessed the humidity dependence of SO 2 uptake on a variety of indoor surface materials.…”

“…174 "The conversion of S(IV)→S(VI) on both iron and zinc was found to have a half-life of ~ 24 hours." 177 In assessing surface uptake of SO 2 , it is common to treat the process as first order, meaning that the uptake rate is proportional to the gas-phase SO 2 concentration. Evidence in some empirical studies supports that assumption explicitly.…”

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.

“…Recently the phenomenon of pitting corrosion has been studied by Hackerman ( l ) , Streicher (2), Carius (3), Rosenfeld (4), Kaesche (5), Franck (6), Engell and Stolica (7), Pourbaix et al (8), Vijh (91, Szklarska-Smialowska and Janik-Czachor ( l o ) , Vermilyea ( 1 l), Pessall and Liu (1 2), Uhlig and Leckie (13), Schwenk and Herbsleb (14) and other authors mentioned in this paper. Schwenk ( 1 5 ) has separated the pitting process in an initiation period and a growth period.…”

“…Der Auf-und Abbau des Oberflachenelektrolyten hangt vom Wassergehalt der Atmosphare und daher von den meteorologischen Kennwerten ab Aufgrund der derzeitigen Kenntnisse iiber den Mechanismus des atmospharischen Rostens. besonders des beschleunigenden Einflusses von Schwefeldioxid sind folgende Einflufjgrofjen fur die Kinetik der aktiven Rostungsperioden wichtig (6)(7)(8)(9)(10)(11)(12). a) Kleine Wassermengen von 1 O-' bis < 100 g .…”
