摘要

Emerging contaminants (ECs) or contaminants of emerging concern (CECs) in water bodies are a growing concern, as they are detrimental to aquatic and terrestrial organisms. CECs enter the water bodies through various sources including domestic, commercial and industrial discharges. This study aimed to detect the presence of CECs in the sewage treatment plants, a potential source of these pollutants in the environment. Treated outlet samples were taken from five major sewage treatment plants (STPs) in Kerala, India. Samples were preconcentrated using solid phase extraction followed by liquid chromatography with quadrupole time-of-flight mass spectroscopy (LC-Q-ToF-MS) analysis for identification of chemical components. The study detected the presence of 24 emerging contaminants including illicit drugs, β-blockers, UV filters, surfactants and chemicals used in the manufacture of pharmaceuticals and personal care products (PPCPs). The results of this study will serve as a critical foundation for future research and policy making aimed at addressing the growing concern of emerging contaminants in the environment.
