check consistency with field sheets Annual Meeting, June , Istanbul, Turkey Data quality control in Q² database In Q² Input * Good * Doubtful * False Experts Almost instantly after data Input Extraction + Detected by defining simple control rules Data year N-2 Statistical tools (time series, statistical tests…)

Annual Meeting, June , Istanbul, Turkey Example of a statistical tool for expert qualification in Q² e.g : DLM graph for Cd in biota (RNO network). The big points are the data identified as « outliers » (potentially doubtful or false).

Annual Meeting, June , Istanbul, Turkey Difficulties encountered: 1.Non qualified data in Q² (=0) transformed in probably good data (=2) in SDN waiting expert qualification 2.Errors in 3 parameters codes : FRPCB28  IFRPCB28, HGDWCF14  D , MMUSHGXX  D Flag modifications concerning LQ or LD : Results = 0 in Q²  flag = 6 in SDN
