SEQUESTRATION AND TOXICOLOGICAL ASSESSMENT OF EMERGING PHARMACEUTICAL CONTAMINANTS USING FUNCTIONALIZED BIOPOLYMER-BASED ADSORBENTS
Keywords:
Emerging contaminants; Pharmaceutical pollutants; Toxicology; Adsorption; Biopolymers; Environmental safetyAbstract
The continuous release of pharmaceutical residues into aquatic environments has emerged as a global environmental and public health concern. Non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, antiepileptics, and β-blockers are frequently detected in surface water, groundwater, and treated wastewater, where they exert toxic effects on aquatic organisms and may pose long-term risks to human health. This study presents a comprehensive assessment of the sequestration of multiple pharmaceutical contaminants—ibuprofen, diclofenac, paracetamol, carbamazepine, and ciprofloxacin—using functionalized biopolymer-based adsorbents. Emphasis is placed on adsorption mechanisms, removal efficiency, and the reduction of toxicological impacts on biological systems. Toxicity evaluation before and after adsorption demonstrates a significant decrease in acute and chronic toxic effects, highlighting the potential of advanced biopolymer composites as sustainable materials for pharmaceutical wastewater treatment.
