Dissolved organic matter (DOM) especially anthropogenic compounds in sewage systems affects their ultimate fate in the environment which is challenging to ascertain the heterogenic nature of the compound and causes co-occurring effects in most aquatic samples. So, our study have focused on current approaches to the chemical and structural characterization of DOM with the detailed classification of individual compounds such as the molecular levels of volatile organic, inorganic materials, drugs and endocrine disrupting compounds. Analytical techniques for example high performance gas chromatography-mass spectrometry (GCMS) with high-resolution liquid chromatography (HR-LCMS), X-ray diffraction (XRD) and three-dimensional fluorescence excitation emission matrix (3D-EEM) has resulted in advancing the parametric studies. In addition, the toxicological assessment of an aquatic organism (zebrafish as a model) has ensued in enlightening the risk of contaminated sources. The result of the research highlighted the efficacy of high-throughput approaches to assess the environmental impact of sewage water.
