Popis: The latest oil spills which have occurred in recent years have shown an increasing demand for detailed assessments of the chemical contamination induced in the water column. Even at low concentrations, hydrocarbons are known to generate impacts, and sanitary questions can be raised. Moreover, non-contaminated and contaminated areas must be distinguished; hence the necessity for developing tools sensitive enough to obtain reliable information on baseline levels. In this context, Cedre has developed different analytical methods which can be partially performed on-site, and which can provide results within a few days, even in the case of pollution far from the laboratory. On the one hand, the SBSE (Stir Bar Sorptive Extraction) technique, performed on-site and coupled with subsequent GC/MS analysis in the laboratory, can be used to quantify PAHs at low levels, around nanogram per liter (ng/L). This paper discusses the possibility of adapting this technique to develop a more operational tool. The lab...
