For sites of former manufactured gas plants (MGP), the compounds that must be considered are BTEX (benzene, toluene, ethylbenzene, and xylenes), 8 of the 16 polycyclic aromatic hydrocarbons (PAHs) generally studied, and, to a lesser degree, phenol and hydrogen cyanide. Given the plausibility of VI and in accordance with current recommendations of the French Ministry of the Environment, measurements of indoor air quality (and outdoor air, for additional analyses) were conducted on two occasions during the winter and summer of 2010. These measurements simultaneously used multiple air sampling devices (Summa® canisters, Gore® modules, air pumps coupled to various matrices; such as XAD2, silica gel, etc.). Phenol and hydrogen cyanide have not previously been quantified (limit of quantification between 0.12 and 2.00 μg/m 3). BTEX and PAHs were found ubiquitously at concentrations on the order of 1 to 10 μg/m 3 for BTEX and naphthalene and one to ten ng/m 3 for PAHs other than naphthalene) at all 14 MGP and both control sites, regardless of where onsite the air was sampled (office, basement or crawl space, or outdoors). These levels (the maximum considered) do not allow us to conclude that the indoor air is degraded according to the official French guidelines for managing potentially contaminated sites and soils. Thus, no excess health risk is expected for residents of these sites because of exposure to possible VI, which cannot be ruled out in view of the ubiquity of some compounds.
