Passive sampling is an approved and accurate method for the assessment of organic compound exposure over long sampling time. This method could be very convenient for the short-time exposure assessment, but passive samplers have to be validated for this use. In this article, the behaviour of two commercial passive samplers (GABIE and Perkin Elmer) under fluctuant concentration conditions is studied. Artificial atmospheres were produced in the laboratory and passive samplers were exposed to different concentration profiles. Both theoretical and experimental results detailed in the paper underline the capability of these two samplers to assess pollutant exposure either when the concentration is unsteady or when the sampling time is short. Then, a suitable sampling strategy is proposed for the assessment of short-term exposure, based on the association of a direct reading photoionization device and passive sampler.
被动采样是一种经认可的、准确的方法，用于在较长采样时间内评估有机化合物暴露情况。该方法对于短期暴露评估可能非常方便，但被动采样器必须针对此用途进行验证。在本文中，研究了两种商用被动采样器（GABIE和珀金埃尔默）在浓度波动条件下的行为。在实验室中产生人工大气，并将被动采样器暴露于不同的浓度分布。本文详细阐述的理论和实验结果均强调了这两种采样器在浓度不稳定或采样时间较短时评估污染物暴露的能力。然后，基于直接读数光离子化装置和被动采样器的组合，提出了一种适用于短期暴露评估的采样策略。
