Chlorine is one of the most abundant elements on Earth’s surface. Traditionally, it was believed that all chlorinated organic compounds were man-made, that chlorine did not participate in biological processes, and that it existed in the environment solely as chloride (commonly known as salt, NaCl). Our research group has discovered that chlorine plays an active role in a complex biogeochemical cycle. Natural chlorination of organic material occurs extensively in various ecosystems, particularly in soils. Our lab and field studies have demonstrated that the chlorination of organic material prolongs the retention of chlorine in soil, challenging the view of chloride as a conservative tracer. Additionally, vegetation appears to play a crucial role in the accumulation and turnover of chlorine in ecosystems. This has significant implications for the turnover of organic material in soil, risk assessment, and the management of radioactive waste, as well as our perception of organochlorine compounds.
Quality in higher education
For several years, I have been involved in education, focusing on program development with student-centred and active learning approaches, particularly in environmental science. I am interested in integrating theory and practice in courses and programs, promoting problem-based learning (PBL), enhancing information literacy, developing skills and career competencies, creating portfolios, fostering interdisciplinary education, student empowerment and ensuring the quality of higher education.
