Euclid is going to reveal the exciting nature of our universe by observing Emission Line Galaxies (ELG) in the redshift region 1 < z < 2, with a high survey area of 15000 deg2. In this talk, I will describe the Systematic Effect of the Line-Misidentification, an important effect of Spectrophotometric observations on high contaminated galaxy samples from interlopers. Then, I will present its impact in measurements of local Primordial Non-Gaussianity (PNG) with Euclid as a baseline experiment.
