Contaminants of Emerging Concern

Contaminants of emergent concern (CECs) in aquatic ecosystems entail a potential risk for the environment, due to their persistent behavior and adverse effect on living organisms during long-term exposition, even at residual concentrations. Conventional Wastewater Treatment Plants (WWTPs) are not designed eliminate CECs properly because treatment technologies enough remove these contaminants, which generates environmental technological challenges. In this review, sources CEC contaminants environments have been discussed detail. Understanding occurrences pathways CECs, effects removal techniques is valuable key proper maintenance global ecological health. This scenario was more explored through harmful impacts including toxic permissible limits. review gathers information about from perspective compiling ecotoxicological effects, conventional advanced methods towards mitigation. Advanced hybrid such as membrane bioreactor with ozonation, reverse osmosis, ultrafiltration shown be promising alternative removal. New oxidation processes assisted non-assisted UVC/H2O2 systems TiO2 photocatalysis were also demonstrated good approach implemented mitigation strategies.
