Dr Charlotte Braungardt
Associate Professor (Senior Lecturer) in Environmental Science
School of Geography, Earth and Environmental Sciences (Faculty of Science and Engineering)
I am Associate Professor (Senior Lecturer) in Environmental Science and my main roles in learning and teaching are in BSc (Hons) Environmental Science and MSc Environmental Consultancy.
I am a member of the Biogeochemistry Research Centre (BGC: http://www1.plymouth.ac.uk/research/bgc/Pages/default.aspx ), sub-group Biogeochemistry and Environmental Analytical Chemistry (BEACh: http://www.plymouth.ac.uk/research/beach ). My research activities centre around the geochemistry of mine waste and its impact on the environment, in particular rivers and coastal zones and agricultural systems.
In my previous career, I graduated as a Dipl.-Ing. Electrical Engineering/Communication Electronics in 1989 and worked as a project engineer in industrial process controll systems for the engineering consultancy Metallurgische Gesellschaft/LURGI in Germany until 1993.
I obtained a BSc Environmental Science at the University of Plymouth in 1996 and continued my scientific training with a Ph.D. in marine geochemistry (Metal biogeochemistry of a mine contaminated estuarine-coastal system in SW Spain) at the same University in 2000. Two EU-funded post-doctoral research fellowships followed between 2000 and 2003, on the projects MEMOSEA (UV digestion of metal complexing natural organic matter and humic substances) and IMTEC (In situ automated monitoring of trace metal speciation in estuaries and coastal zones).
Between 2001 and 2006, I took on various part-time lecturing roles in environmental science and marine science and obtained the LTHE (Learning and Teaching in Higher Education) qualification. My permanent position as lecturer at the University of Plymouth commenced in 2006.

My teaching activities centre around our BSc Environmental Science programme and the MSc Environmental Consultancy course. As a lecturer, my focus is on catchment science, geochemistry, water resources, scientific method and skills development; the latter including practical scientific investigations, providing opportunities for work experience, as well as introducing advanced IT skills, such as GIS, to the programme.
With the help of funds from the Centre of Excellence in Learning and Teaching (Experiential Learning CETL), I developed an interdisciplinary residential fieldcourse for Stage 2 students of our BSc Environmental Science course with partner universities in Hong Kong and PR China. The academic theme of this course is the environmental and social impact of rapid economic development and its links with post-industrial consumer societies. Students investigate air and water pollution, evaluate coastal conservation measures and use biomarkers to assess ecosystem health. The unique character of this field course, however, arises from the close collaboration of students from Sun Yat-sen University of Guangzhou, City University of Hong Kong and Plymouth University in the pre-field course preparation of research projects, which are then jointly carried out in the field and laboratories in China.
My research interests lie in the geochemistry and biogeochemistry of catchment systems, from headwaters to estuaries and into the coastal zone. Current research projects investigate point and diffuse sources of elements associated with metal mining activities and the impact of contamination on the aquatic environment, soils and the assessment of risk for humans from uptake of metals into agricultural products. For this work, collaboration with external partners include local organisations (e.g. Tamar Valley Service), as well as the Environment Agency, Camborne School of Mines, the British Geological Survey, the International Zinc Association and the European Copper Institute. The application of novel techniques to assess the impact of metal inputs into catchments have been the focus of recent activities. These integrate metal speciation measurements obtained with an in-situ voltammetric profiling system with speciation modelling and ecotoxicological studies on oyster embryo bioassays. The MARA bioassay (Microbial Assay for toxic Risk Assessment) is used to determine toxic effects of mixtures of metals and organic compounds.
