Occurrence, Risk Assessment and Removal of Emerging Contaminants in Aquatic Environment

Overview & Synopsis

The pervasive presence of emerging contaminants (ECs) in aquatic environments poses a significant and escalating challenge to global public health and ecological stability. This Reprint, "Occurrence, Risk Assessment, and Removal of Emerging Contaminants in Aquatic Environments," presents a curated collection of cutting-edge research that addresses this multifaceted issue. The articles compiled herein explore the complex dynamics of ECs, from their detection and transport to their ultimate fate. The contributions delve into innovative treatment technologies, including the optimization of biological co-metabolism using waste streams for recalcitrant pollutant degradation, and the development of novel photocatalytic membranes that integrate separation with advanced oxidation to remove persistent antibiotics. The Reprint also provides critical field data on the occurrence and risk of specific classes of contaminants, such as organophosphate flame retardants and disinfection by-products, highlighting the limitations of conventional wastewater treatment infrastructure. Furthermore, it explores holistic management strategies, from the full-chain reprocessing of legacy landfilled sludge to the implementation of intelligent, AI-driven chemical dosing systems that enhance plant efficiency and sustainability. Complemented by comprehensive reviews on surfactant-enhanced remediation and the critical nexus of antibiotics and antimicrobial resistance in wastewater, this Reprint offers a vital, multifaceted perspective for researchers, engineers, and policymakers that are dedicated to safeguarding our water resources.
