Occurrence of Emergent Contaminants in Water: Sources and Remediation Strategies for a Clean and Sustainable Future

The increasing occurrence of emerging pollutants in water has become a significant global environmental concern. Their persistence and potential adverse effects on human health and ecosystem integrity necessitate innovative mitigation strategies, emphasizing the development of sustainable water treatment technologies and regulatory frameworks to safeguard water quality. Photocatalysis has gained a huge interest amongst the numerous methodologies for wastewater treatment in view of its eco-friendly approach, high performance and low cost, involving chemical reactions in the presence of a light source and a catalyst to produce new substances or transform existing molecules into harmless forms.
