The Chemical Engineering department was honored to host Dr. Despo Fatta-Kassinos, a highly cited researcher in "Environment and Ecology," for a seminal lecture on May 23, 2023. The lecture, titled "Enhancing the Circular Economy in the Water Sector by Addressing the Contaminants of Emerging Concern in Wastewater," shed light on urgent challenges related to water reuse, particularly in agriculture. Dr. Fatta-Kassinos delved into the complexities of contaminants of emerging concern (CEC), including pharmaceutical compounds and disinfection by-products. She explored their transformative potential risks to human health and ecosystems. The lecture provided strategies adhering to the "One Health" approach for assessing wastewater quality and discussed the role of disinfection in the era of rising antimicrobial resistance. The event offered an invaluable opportunity for students and faculty to enrich their understanding of water resource management and sustainability.
