Persons
Zhongqi He is a Research Chemist at the USDA-ARS, Southern Regional Research Center, in New Orleans, Louisiana. For the past 20+ years, Dr. He conducted research on the applied and environmental chemistry of agricultural products, byproducts, and plant nutrients. Dr. He has made outstanding contributions in quality and utilization of agricultural products and byproducts, the impacts of short- and long-term manure and agricultural byproducts application on soil nutrient status, and characterization of P and C bondings in agricultural products and plant nutrients by advanced spectroscopic techniques.
Fengchang Wu is a professor and Director of the State Key Laboratory of Environmental Criteria and Risk Assessment of Chinese Research Academy of Environmental Sciences, Ministry of Environmental Protection, China. For the past 20+ years, Dr. Wu has researched and taught the biogeochemistry and toxicology for lake pollution control and environmental quality. His current research focuses on freshwater eutrophication and pollution reduction at the interface of the environment, technology, and society. Dr. Wu has made significant contributions to the development and applications of lake environmental quality standards, risk management, environmental engineering, and policy.
