Edible oil residues (EOR) and detergents/soaps (NBDS) are a considerable problem in the water systems. The layer due to presence of these residuals covers the water surface damaging the aquatic life by hampering the sun light to touch its bottom, diminishing algae quantity and, consequently, microorganisms and fishes, which depend on it to survive, changing the local biosphere. Knowing this potential effect, the objective was monitor edible oil residues and detergents/soaps presence in two sewage treatment station located in Brazil. To this, samples were collected from 3 different sewage treatment stages and evaluated by ultraviolet-visible spectroscopy. Chemometrics was applied to recover spectra profiles and relative concentration of residuals. The results indicate that the proposed methodology is feasible to monitoring these residues in sewage.
