Research Interests

1.    Environmental Fate and biological effect of pollutants

We focus on processes of sorption, mineralization, degradation, metabolism, bioaccumulation and transport of pollutants in environment, their transformation pathways and products, and structure of bound residues in environment. Special interests are the degradation and uptake of pollutants by soil fauna (e.g. earthworm) and plants and the microbial degradation in water saturated environments (e.g. paddy soil) and pure culture. Organic pollutants under current study include endocrine disruptors (nonylphenol, steroid estrogens), chlorophenols, perfluorinated octanoic acid (PFOA), PAHs and some PPCPs. Main techniques are stable (13C) and radioactive (14C) isotope tracer combined with instrumental analyses (NMR, GC-MS, LC-MS).

 

2.    Transformation of natural organic matter and global environmental change

We focus on stabilization and destabilization processes of soil organic matter, humification of biopolymers of plant and microbial origins, chemical structure of humified precursors of humic substances.  Special interests are mineralization and transformation of phenolic and nitrogen-containing compounds by soil-feeding animals and in anoxic environments, impacts of global change on soil carbon stability. Main techniques are stable (13C, 15N) and radioactive (14C) isotope tracer combined with instrumental analyses (NMR, GC-MS, LC-MS).

 

3.    Remediation of contaminated environment

We focused on techniques for decontamination and remediation of polluted soil and aquifers using microorganisms, plants, and animals, and surfactant-assistant in situ bioremediation techniques. Special interests are bioaugmentation of plant-associated fungi and soil macrofauna for bioremediation of PAHs- and chlorophenols- contaminated soil. 

 

4.    Synthesis and application of isotope-labeled organic compounds

We label organic compound by chemical synthesis and using microorganism and plant and provide labeling service. Special expertise is the preparation of 13C-, 14C-, and 15N-labeled natural organic biopolymers (protein, peptidoglycan, humic substances, etc), phenolic compounds (e.g. catechol, vanillin, p-hydroxybenzaldehyde, p-coumaric, caffeic, and ferulic acid), and xenobiotics (nonylphenols, chlorophenols, etc). So far, we have synthesized more than 30 radioactive and stable isotope labeled compounds, which have been applied to studies on humification process of natural and anthropogenic organic matter in soil and aquifer environments, environmental fate of pollutants, their degradation pathway, structures of metabolites and residues, and bioaccumulation.
