to assess water safety as of paramount importance. Water is polluted by a manifold of inorganic and organic pollutants and new strategies are required in aso-varigated scenario. Within the framework of the Equality ATN project the achieved results encompass. Development and application of a protocol of investigating the photochemical fate of contaminants of emerging concern and their degradation products as well as advanced oxidation processes a loose adhesion of the significance of photochemical reactions and their contribution to the aionic transformation of contaminants and water systems. Understanding the role of the major reactive species generated during the photo degradation process assessment of the toxicity of contaminants and their degradation products with the employment of integrated toxicity approach. Use of excitation emission matrices coupled with paraffack analysis as an indicator of dissolved organic matter contaminants abatement along with drinking water treatments. In this regard, tracking this group of substances through fluorescent excitation emission matrices and parallel factor analysis, paraffack, is gaining momentum.
