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 15-16 2015, 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  D2930515, MMUSHGXX  D2930561
3. Flag modifications concerning LQ or LD :
Results = 0 in Q²  flag = 6 in SDN
