Abstract

The escalating problem of environmental pollution can be attributed to the accelerated pace of global development, which often prioritizes human needs over planetary health. Despite huge global attempts endeavours to mitigate legacy pollutants, the uninterrupted introduction of novel substances such as the emerging organic micropollutants (EOMs) represents a significant menace to the natural environment and all forms of life on the earth. The widespread occurrence of EOMs in water and wastewater is a consequence of both their growing consumption as well as the limitations of the conventional wastewater treatment methods containing such pollutants resulting in deterioration of water quality and its supplies as well as this is a significant challenge for researchers and the scientific community alike. EOMs possibility to bioaccumulate, their toxic properties, resistance to degradation, and the limitations of conventional wastewater treatment methods for quantitative removal of EOMs at low concentrations give a significant environmental risk. These compounds are not commonly monitored, which exacerbates further the problem. Therefore the wide knowledge concerning EOMs properties, their occurrence as well as awareness about their migration in the environment and harmful effects is also extremely important. Therefore the EOMs characterization of various types, their classification and sources, concentrations in the aquatic systems and wastewaters, existing regulatory guidelines and their impacts on the environment and human health are thoroughly vetted in this review. Although the full extent of EOMs' effects on aquatic ecosystems and human health is still in the process of investigations, there are evident indications of their potential acute and chronic impacts, which warrant urgent attention. In practical terms the results of the research presented in this paper will help to fill the knowledge gaps concerning EOMs as a serious problem and to raise public awareness of actions to move to sustainable pollution management practices to protect our planet for future generations are vital.
