Short-chain chlorinated paraffins (SCCPs) are a class of organic pollutants used in many industrial applications, and released into the environment , whose analytical determination is very challenging. Although at present there is no fully validated measurement procedure which might be applied in routine monitoring, the European Water Framework Directive (WFD) requires regular monitoring of this class of compounds at river basin scale starting from 2007. to assess the status quo in the analysis of SCCPs in relation to the requirements posed by the WFD, an interlaboratory comparison on the quantification of SCCPs in an extract of an industrial soil has been organised. Six laboratories participated in the present exercise using three different techniques, gas chromatography (GC) coupled to mass spectrometry (MS) in the electron capture negative ionization (ECNI) mode, GC with atomic emission detection (AED), and carbon skeleton GC-MS. the reported result ranged from 8.5 mg L-1 to 3200 mg L-1. This confirms that reliable quantification of SCCPs is still very difficult to achieve and that comparability of SCCP data reported to the European Commission is at least questionable.
