Abstract:

Emerging contaminants, such as pharmaceuticals, hormones, UV filters, and pesticides, are increasingly detected in aquatic environments, including wastewater, seawater, and groundwater. Their persistence, bioaccumulation, and potential effects on ecosystems and organism health make them a significant environmental concern. Beyond their scientific relevance, these pollutants provide an authentic context for engaging students with real-world analytical challenges.

This work presents an educational innovation in which undergraduate students in chemistry, environmental science, or pharmacy carry out the determination of emerging contaminants in water samples. Using a simple and accessible extraction method followed by chromatographic analysis, students validate methodologies, analyse real samples, interpret and discuss the results, and explore the practical application of analytical chemistry techniques to environmental issues while assessing the implications of their findings for water quality evaluation and environmental management.

Implemented within a project-based learning framework, students not only analyse real environmental data but also reflect on their role in promoting environmental awareness, and develop critical thinking, and problem-solving skills, creating a tangible connection between classroom learning and global sustainability objectives. In this sense, the proposed educational framework supports Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being), SDG 6 (Clean Water and Sanitation), and SDG 14 (Life Below Water).

Preliminary laboratory applications indicate that integrating real environmental data into experimental activities effectively promotes students’ understanding of how chemistry informs environmental monitoring and management, while also providing a meaningful, hands-on experience that bridges theory and practice. Overall, this approach demonstrates how linking research and teaching enhances learning outcomes and increases students’ appreciation of chemistry’s societal relevance in addressing global environmental challenges.
