How to manage the development of new passive samplers to implement these tools in environmental monitoring programs

Abstract : Passive samplers are usually small tools, directly introduced in water, which will be analyzed after several days or onths immerged in the studied medium. Compared to grab sampling, advantages of passive sampling are mainly related to in-situ preconcentration, lower limit of detection, lower transport costs and storage, higher stability of sampled compounds and determination of time weighted concentration. However, there remain some gaps in the battery of available passive sampling devices, for very hydrophilic and/orionisable substances, for some priority substances with biota standards (e.g. PFOS), for substances with extremely low EQS water values (e.g. dichlorvos, dicofol and heptachlor). And these would need to be addressed before they could be implemented in the context of Water framework Directive (WFD) and routine monitoring. After a short presentation of advantages and drawbacks of various tools for organic contaminants in the context of WFD, we will focus our talk on an emerging tool (passive rod sampler) which has been recently introduced. The development of this new tool especially design to cover a wider range of hydrophobicity has been a challenging task in order to reduce the constraints for the utilization of passive samplers and enlarge their applicability range. This sampler will be used as a case study during the talk in order to have a more explicit viewpoint of the pros and the cons related to such tool. A second original tool, DGT for glyphosate, will be also described with the same approach. The presentation will be concluded by a list of tasks needed before the implementation of such new tools in environmental monitoring programs.
