**About the Editors**

## **Hucai Zhang**

Dr. Hucai Zhang is a Distinguished Professor at Yunnan University in Kunming, China and the Academician of the Russian Academy of Natural Sciences (RAEN). Professor Zhang has worked on Late Pleistocene paleolake evolution and environmental changes in arid western China and eastern Sahara Desert, the relationship between environmental changes and faunas (human) in the Middle-Late Pleistocene in Northeast China, limnology and its implications for changes in the Asian monsoon and regional ecosystems on the Qinghai-Tibet and Yunnan-Guizhou Plateaus, changes in the southern African monsoon regime and its relationship to human evolution, and heavy metal pollution and eutrophication in plateau lakes.

Professor Zhang participated in the DFG Africa Sahara Special Research Project SFB69 (1992–1993) and the International Ocean Discovery Project (IODP) Expedition 361—Southern African Climates. He has undertaken Key Programs, Key International Cooperation Projects, General Programs of the National Natural Science Foundation of China, the Leading Scientist Plan of Yunnan Province and Senior Talent Projects. He has published more than 300 research papers in internationally recognized journals including Cell, Nature Communication, Science, Radiocarbon, Palaeogeography Palaeoclimatology Palaeoecology, Quaternary Research, the Journal of Geophysical Research, Science China, Science Bulletin and Quaternary Sciences among others. His books include Superficial Elemental Geochemistry and Theoretical Principles (Lanzhou University Press, 1997).

#### **Jingan Chen**

Prof. Dr. Jingan Chen is a professor of the Institute of Geochemistry, Chinese Academy of Sciences. He has engaged in water environment and security, lake eutrophication, sediment pollution and control, biogeochemical cycles of nutrients and isotope geochemistry. In recent years, the main work has focused on lake eutrophication, sediment pollution and control, biogeochemical cycles of nutrients and construction of dynamic models of pollutants in deep and shallow waters, including lakes and reservoirs in order to establish a comprehensive understanding of the migration dynamics of pollutants in water bodies. He has published more than 200 scientific research articles.

## **G.D. Haffner**

Prof. Douglas G. Haffner is a professor of the University of Windsor, Canada Research Chair, founder of the Great Lakes Institute for Environmental Research (GLIER). He has engaged in water pollutant detection, chemical impact research. In recent years, the main work has focused on the construction of dynamic models of pollutants in deep and shallow waters in order to establish a comprehensive understanding of the migration dynamics of pollutants in water bodies. He has published more than 150 scientific research articles. He has worked with the scientific researchers from the United States, New Zealand, Indonesia, Caribbean island countries, and China for many years.
