Ecological status assessment in waterbodies depends on standards application in the field and in the laboratory. They induce many uncertainties associated to natural or human variabilities. The aim is (1) to study the effect of some uncertainties on french indices based on macroinverterbrates and macrophytes, (2) to estimate them, and (3) to observe their propagation on final ecological status.Concerning macroinvertebrates, we are interest in the intrasubstrate variability and the surveyor effect in IBGN, IBG DCE and I2M2. Concerning the macrophytes, we focus on surveyor impact in IBMR. Indices variation appears and could lead to ecological status changes. Control quality approach could be proposed to reduce uncertainties effects.L’évaluati...
