The passive sampling technique has been used for a long time in industrial hygiene as a parallel method to the active sampling for the determination of organic airborne compounds. The agreement between passive and active sampling has been widely discussed and validation protocols have been developed and standardized. Recently, the passive sampling technique has also been applied for indoor and outdoor air monitoring. The low concentrations found in ambient air require long periods of sampling, generally between two and four weeks. On the other hand, the ambient air passive samplers are exposed to atmospheric conditions of very low stability, quite different from the industrial hygiene environment. As a consequence, it is not possible to transfer the passive sampling validation from the industrial to the ambient environment. A new validation for ambient air passive samplers must therefore be carried out in order to establish this technique as an alternative method for detecting organic airborne compounds.
