5. Annual Meeting, June 15-16 2015, Istanbul, Turkey Difficulties encountered: Data < detection limits and varying detection limits Proposed solutions:  QF 6 and value of the detection limit P01 missing, eg. in sediment or PCB congenera  P01 request according to list of priority substances following the call requirements (EU Dir. 2013/39/EU) Difficulties in finding P01 from P02 MTSDMetal concentrations in sediment: deprecated term CDAFWC01Concentration of cadmium {Cd} per unit volume of the water body [dissolved plus reactive particulate (MTWDDissolved metal concentrations in the water column) CDUFWC02Concentration of cadmium {Cd} per unit volume of the water body [dissolved plus reactive particulate phase] (MTWTTotal metal concentrations in water bodies) Sometimes Preferred labels coincide (this can create confusion) MCRSP012Concentration of chromium {Cr} per unit dry weight of sediment Sed_CrConcentration of elemental chromium per unit mass of dry sediment
