“…Passive sampling, whose theoretical fundamentals were described in detail and summarized by Crump,( 185 ) is enjoying increasing popularity in indoor air testing, since it can be employed without causing any nuisance to room users. Different types of formaldehyde passive samplers have been employed.…”

“…In the case of active sampling, air is passed through a sampling device using a pump and the air volume is accurately determined. A passive sampler is a device which is capable of taking air samples at a rate controlled by diffusion through a static layer or permeation through a membrane . The flow of pollutants into the passive sampler is proportional to the difference of concentrations in the ambient air ( C air ) and on the surface of the passive sampler ( C A ), as shown in eq .…”

“…Passive sampling, whose theoretical fundamentals were described in detail and summarized by Crump, is enjoying increasing popularity in indoor air testing, since it can be employed without causing any nuisance to room users. Different types of formaldehyde passive samplers have been employed. − However, it must be borne in mind that passive collectors are usually left in a room for days or even weeks at a time without continuous monitoring by the analyst, and this means that the possibility of tampering cannot be excluded.…”

“…Diffusive samplers are small and convenient tubes and badges that can be placed in a building by an investigator, or sent to the occupants of buildings under investigation [17]. The diffusive sampler provides a measure of the mean concentration over periods of days or weeks in the building under conditions of normal occupation.…”

There is an increasing concern about the indoor air quality (IAQ) in non-industrial buildings. The main exposure to air pollutants for most people occurs in indoor environments and this can have an important influence on their health and wellbeing and affect productivity at the workplace. Many environmental parameters need to be considered when assessing the quality of the air in an indoor environment. Any investigation of IAQ requires a clear definition of the objectives of measurement and a strategy for actions required to meet those objectives. This paper outlines the factors that determine IAQ and provides guidance on designing an appropriate sampling strategy, including the selection of methods, for one parameter, organic compounds in the vapour phase.

“…It allows the sampling of most VOCs but can also sample SVOCs and particles [ 17 , 18 ]. In some studies, passive sampling has been used for VVOCs but has shown an underestimation of their concentration [ 19 ]. Active sampling is preferable for sampling VVOCs [ 20 ].…”

There are several analytical procedures available for the monitoring of volatile organic compounds (VOCs) in the air, which differ mainly on sampling procedures. The Coriolis micro air sampler is a tool normally designed for biological air sampling. In this paper, the Coriolis micro bio collector is used to evaluate its ability to sample organic contaminants sampling and detecting them when combined GC-MS. We also compare the use of the Coriolis micro with a standardized sampling method, which is the use of a lung box with a Nalophan® bag. The results show that the Coriolis micro sampling method is suitable for the sampling of organic contaminants. Indeed, the Coriolis micro allows to sample and detect mainly semi-volatile molecules, while the lung box/Nalophan® bags allow to sample more volatile molecules (highly volatile and volatile). These results were confirmed in the controlled air lab with a slight difference with the field. The simultaneous use of the both techniques allow to sample and detect a larger number of molecules with specific physicochemical properties to each sampling technique. In conclusion, the Coriolis micro can sample and detect volatile organic compounds present in air. We have shown that the development of alternative sampling methods and the use of non-target analysis are essential for a more comprehensive risk assessment. Moreover, the use of the Coriolis micro allows the detection of emergent molecules around the Thau lagoon.
