Laboratory of Environmental BioGeochemistry

(EBG-Lab)

About US

Based at Hiroshima University, the Environmental BioGeochemistry Laboratory (EBG Lab) is a research group dedicated to understanding and solving complex environmental issues. We bridge the gap between fundamental science and practical applications to protect our planet's vital resources. Our research focuses on high-priority pollutants, such as Toxic Elements and Microplastics. Our research specifically targets the interfaces of Soil-Sediment and Water systems, where the most critical biogeochemical transformations occur. In our current projects, we investigate the biodegradation of plastics in Coastal Blue Carbon Ecosystems (BCEs), specifically in mangrove forests and coral reefs across Asia. We leverage advanced specialized techniques across geochemistry (ICP-MS/OES, XRD), microbiology (microbial isolation, DNA sequencing), and material science (SEM-EDS, FT-IR, XPS) to address these environmental challenges.
