“…Investigating the simultaneous removal of multiple OMPs by using a photoanode will give information on the selectivity of the photoanode and the removal kinetics of each OMP present in the aqueous solution. The exposure of all three OMPs (ACT, BTA, PRO) even at lower concentrations of below 200 μg L − 1 can cause adverse effects on the reproductive system of aquatic organisms [45] and also intake of these OMPs by humans through drinking water can cause inflammation, tissue damage and serious problems in digestion by changing the gut microorganism population [46]. We believe that like other pharmaceuticals, ACT and PRO at a concentration below 150 μg L − 1 can act additively as a mixture of pharmaceuticals and can cause lethal or sub-lethal toxic effects to aquatic organisms, therefore, their complete removal from surface water should be of significant importance.…”
