Annual Meeting, June , Istanbul, Turkey Difficulties encountered: Inclusion of Hazardous Substances invalidated previous CDI generation process based on national nutrient station systems (CDI numbers refered directly to data) Negative nutrient concentrations stored in national database had to be manually changed to <DL in ODV All Hazardous Substance station names have been revised/changed in may 2015 so CDI generation was put on hold until these where in place Some P01 terms specific to Danish data not defined Recalculation of organotin from ”Sn” to molecule µg/kg has to be implemented
