1. Investigation, analysis, and remediation of heavy metals in contaminated riverine streams using a mercury stable isotope technique.
2. Developing a simple & user-friendly model for simulating heavy metal sources, biogeochemical cycling, and fate in natural terrestrial ecosystems.
3. Statistical methods of interpreting and evaluating a national-scale health-relevant data (ie, blood heavy metal & persistent organic pollutants concentrations, dietary pattern and consumption levels, life history characteristics).
