•Fate of Chemicals in Wastewater
My mian research interests are focusing on the fate of chemicals in Chinese wastewater treatment plants (WWTPs):
1) Designing the novel passive sampler for organic chemicals in wastewater treatment system;
2) Investigating the occurrence of chemicals in Chinese WWTPs and their environmental fate;
3) Evaluating the effectiveness of processes and efficiency for daily use chemicals;
4) Studying the removal of priority substances through the sewage treatment process in China;
5) Modeling the fate and behaviors of chemicals in WWTPs;
6) Assessing the environmental/health risk of chemicals in wastewater and biosolids and assessing the risk/impact of agricultural use or other use.
•Environmental Geochemistry of Persistent Toxic Substances
Environmental geochemistry of persistent toxic substances (PTS), especially on persistent organic pollutants (POPs) and heavy metals, including:
1) Environmental fate and behavior of POPs and heavy metals in different matrixes;
2) Sorption, degradation, bioavailability of POPs and heavy metals;
3) Risk assessment of POPs and heavy metals;
4) Soil and groundwater remediation of POPs and heavy metals.
•Soil and Groundwater Contamination and Remediation
Soil and groundwater contamination is great challenge in China, which also interests me:
1) Designing the novel sampling method for soil and groundwater monitoring;
2) Source identify for groundwater contamination;
3) Combined effect on inorganic and organic contaminatants in soil and groundwater;
•Evidence of Climate Change
1) Case studies of climate change on region scale;
2) Environmental response in acid region on climate change;
3) Historical records on climate change (sediment, pollen, peatland, vegetation, and so on);
4) Isotopic evidence/ measurement of climate change.
