Antibiotics are bioactive substances, used as human and animal medicines for illness prevention, diseasetreatment and growth promotion. They are considered to be pseudo persistent given their continuous input inthe environment. Antibiotics enter agro ecosystems through several routes such as wastewater irrigation, soilapplication, animal manures or bio-solids which are mostly biologically active thus creating potential risks to theenvironment. They are present in different environmental matrices at low concentrations as residues. Antibioticresidues enter the environment primarily via urine, feces and manure from humans and animals after they havetaken the medication, as well as from manufacturing wastewater. These residues contaminate the soil, surfacewater, and groundwater by leaching or runoffand ultimately breed antibiotic-resistant bacteria (ARB) and genes(ARG). These triune threat viz antibiotics, ARB and ARG have not been effectively removed by various treatmentin wastewater treatment plants. Here, we put together existing knowledge and aim at providing in-depthknowledge to the extent to which a wide range of treatment processes determine the ultimate fate of antibiotic-bred threats (ARB and ARG) in conventional and advanced wastewater treatment. The use of antibiotics isinevitable, hence studies focusing on minimizing their discharge into the environment viz-a-viz support futureregulatory measures are of great importance
