T1 - CCQM-K126: low polarity organic in water: carbamazepine in surface water N2 - This study aimed to assess the measurement capabilities of participating National Metrology Institutes/ Designated Institutes (NMIs/DIs) and expert laboratories in determining of low-polarity organics in surface water. This comparison was organized by Government Laboratory, Hong Kong (GLHK). At the CCQM Organic Analysis Working Group (OAWG) Meeting held in November 2012 in Hong Kong, GLHK initially proposed a CCQM key comparison and a parallel pilot study programme on pharmaceuticals in surface water. Further discussion at the CCQM Meeting held in April 2014 in Paris, the OAWG approved a CCQM Track C comparison (CCQM-K126) on low polarity pharmaceuticals in surface water. In the meeting, the programme was supported by more than six National Metrology Institutes/ Designated Institutes (NMIs/ DIs). CCQM-K126 officially commenced in July 2014 and had registration from nine NMIs/DIs. Participants were provided two bottles (40 mL each) of surface water and were requested to determine the mass fraction of spiked carbamazepinein in surface water. The coordinator received nine sets of results from eight NMIs/DIs in February 2015. Apart from one using an immunoassay technique, all participants applied isotope dilution liquid chromatography-tandem mass spectrometry (ID-LCMS/MS) technique as their determination technique.

ED - Cervera, Miguel T1 - Modelling of fluidised geomaterials: the case of the Aberfan and the Gypsum tailings impoundment flowslides N2 - The choice of a pure cohesive or a pure frictional viscoplastic model to represent the rheological behaviour of a flowslide is of paramount importance in order to obtain accurate results for real cases. The principal Goal of the present work is to clarify the influence of the type of viscous model—pure cohesive versus pure frictional—with the numerical reproduction of two different real flowslides that occurred in 1966: the Aberfan flowslide and the Gypsum tailings impoundment flowslide. In the present work, a depth-integrated model based on the v-pw Biot–Zienkiewicz formulation, enhanced with a diffusion-like equation to account for the pore pressure Evolution within the soil mass, is applied to both 1966 cases. For the Aberfan flowslide, a frictional viscous model based on Perzyna viscoplasticity is considered, while a pure cohesive viscous model (Bingham model) is considered for the case of the Gypsum flowslide. The numerical approach followed is the SPH method, which has been enriched by adding a 1D finite difference grid to each SPH node in order to improve the description of the pore water evolution in the propagating mixture. The results obtained by the performed simulations are in agreement with the documentation obtained through the UK National Archive (Aberfan flowslide) and the International Commission of large Dams (Gypsum flowslide).
