(1) Biosorption of pollutants
More than 20 bioadorbents for toxic elements and organic pollutants were screened from fungi, algae and higher plants, which can be widely applied to wastewater treatment. The sorption behavior and mechanisms were also elucidated.

(2) Organic ligands from microbes, plants and animals in the environments
The metal complexation behavior of microbial extracellular polymeric substances was examined by fluorescence spectroscopy, FTIR and electrochemical methods. Our studies showed that some exudates from microorganisms are effective metal organic ligands, which may significantly affect the mobility and bioavailability of metals in environments.

(3) Toxic effects of pollutants on photosystem II of algae
Toxic effects of some metals, antibiotics and pesticides on electron transport, charge recombination and energy distribution in PSII were elucidated. Some new target sites of pollutants and action mode were found.
