Conferences have a way of pulling you out of your own data and reminding you where your work fits in the bigger picture. I recently attended the 14th Scottish Environmental and Analytical Chemistry Symposium, hosted at the University of Aberdeen, where I presented a poster on my PhD research and spent a day immersed in discussions spanning environmental monitoring, analytical innovation, and applied chemistry.
My poster focused on the development of array-based fluorescent sensing strategies for detecting micropollutants and assessing potential ecotoxicity in treated sewage sludge. Sludge is increasingly viewed as a resource rather than a waste, yet the presence of trace contaminants such as pharmaceuticals and endocrine-disrupting compounds complicates its reuse. While established techniques like LC–MS remain indispensable, they are not always practical for rapid or large-scale screening. My work explores how cross-reactive host–dye sensor arrays, combined with multivariate analysis, can provide fast, chemically interpretable fingerprints of complex samples.
Presenting this work in a room full of environmental and analytical chemists was both grounding and motivating. Many conversations naturally gravitated toward how such sensing approaches could complement mass spectrometry, acting as a front-end screening tool rather than a replacement. Questions around robustness, matrix effects, and real-world applicability were especially valuable, reinforcing the importance of testing beyond idealised systems and pushing towards realistic sludge matrices.
One of the highlights of the symposium was seeing the diversity of approaches being applied to shared environmental challenges. From wastewater-based epidemiology and PFAS monitoring to microplastics, electrochemical sensors, and sustainable remediation materials, the programme highlighted how multifaceted environmental chemistry has become. The keynote lecture, which reflected on the enduring value of fundamental techniques alongside modern analytical tools, particularly resonated with me as an early-career researcher navigating between innovation and rigour.
Equally important were the informal discussions during the poster session and breaks. These conversations often moved beyond individual projects, touching on career paths, methodological trade-offs, and the realities of translating research into practical impact. As a PhD student, it was encouraging to engage with others at similar stages, as well as with researchers whose work spans academia, applied research, and industry-facing science.
Coming away from the symposium, I was reminded that progress in research is not only about refining experiments or improving figures, but also about learning how to communicate ideas clearly, listen critically, and situate your work within a broader scientific landscape. Events like this play an important role in shaping that perspective.
I’m grateful to the organisers and the Royal Society of Chemistry Analytical Division for creating a supportive platform for early-career researchers, and I’m looking forward to building on these discussions as my project moves toward more complex samples and real-world applications.
