1. About IGCAS

1.1 Brief introduction to IGCAS
The Institute of Geochemistry, Chinese Academy of Sciences (IGCAS) was founded in 1966, which was established in Guiyang through the merger of Geochemistry Group of the Institute of Geology, CAS, Guiyang Institute of Chemistry, CAS and Kunming Field Station of the Institute of Geology, CAS. Currently, IGCAS has set up the State Key Laboratory of Ore Deposit Geochemistry, the State Key Laboratory of Environmental Geochemistry, the Key Laboratory for High-temperature and High-pressure Study of the Earth's Interior of CAS, the Center for Lunar and Planetary Sciences, and the Guizhou Engineering Research Center of Integrated Utilization of Mineral Resources of CAS, all of which are equipped with advanced equipment and facilities, and the assets of the instrument and equipment are more than 200 million RMB.

IGCAS aims to study the revolution of the Earth and planetary as well as the geochemical process and resource environment effect of material circulation among various spheres of the Earth, improve and innovate the system of geochemical theories and applications, greatly enhance China's science and technology capacity in solving solid mineral resources development and ecological environmental problems, and become an important base and high-level talents cradle in the Earth and planetary evolution, solid mineral resources and ecological environment.

IGCAS has formulated the development plan for the next five years, and the three major breakthroughs to be achieved are: 1) the law of elements super-enrichment and the prediction for deep ore prospecting; 2) the process and treatment technology of rocky desertification and heavy metal pollution; 3) The Earth’s interior material and planetary science. The five cultivation directions are: 1) geochemical basic theory and method; 2) the mineralization law of the next generation strategic mineral resources; 3) efficient and clean utilization of mineral resources; 4) water resources and water environment of the plateau river and deep water lake reservoir; 5) geochemical records of environment and climate change.

1.2 Brief introduction to SKLEG
Since it was opened in 1991, built and approved by state in 1995, the State Key Laboratory of Environmental Geochemistry (SKLEG) has integrated the environmental science and the Earth science, combining current environmental phenomena with long-term evolution of the Earth’s history, and combining natural evolution of the Earth system with human impact. To reveal the share between natural and human factors which causes environmental quality variation, the laboratory has conducted systematic study in the evolution law of geochemical process between the interactions of the Earth’s spheres.

1.2.1 Laboratory goals
Targeting the environmental problems which restricts the regional and global economic and social development and influences human health, SKLEG carries out basic and applied research about the geochemical process on the Earth’s surface and regional response to the global changes, and constructs theories of environmental geochemistry of natural and anthropogenic processes. The research results provide a scientific basis for the government to make decisions about the development and utilization of the land resources, protection and control of the ecological environment, and services for improving human health. SKLEG aims to be a base for the national environmental protection research and talent training.

1.2.2 Main research areas and objectives
Based on the integrity and interdependence of the Earth’s environment, targeting the problems of the region environment(especially the Karst region in southwest China) and global change, and applying the geochemical theories and methods, SKLEG studies the transportation and circulation law about the chemical elements, isotopes and compounds which are released from natural and anthropogenic processes between all spheres of the Earth’s surface layers (rock / soil circle –hydrosphere - atmosphere - biosphere) and its impact on the eco - environmental system, develops and completes the environmental chemistry theory, assesses the share of natural and anthropogenic interactions that leads to the changes in environmental quality, and then provides better services for the environmental protection, human health and social sustainable development.

Main research fields and objectives:
Geochemical processes and environmental quality changes in the environment of the Earth’s surface: studying the biogeochemical processes and their ecological and environmental effects of the material cycling between different spheres of the Earth’s surface; revealing the relationship between the biogeochemical cycling and the change of the ecological environment; and providing scientific basis for environmental protection and government decisions.

Geochemical records of environmental and climate changes: studying various geochemical substitute indexes of environmental and climate changes; revealing climate and environmental changes in the Earth’s past (especially Holocene Epoch and last 2000 years) and its relationship with the development of human society; and providing the basic data for the establishment of the global and regional environment, climate change model and prediction theory.

Geochemical environment and human health: studying the transportation and transformation of the harmful substances and the corresponding control mechanisms; revealing the coupling relationship between the geochemical environment and human health; and providing scientific theoretical basis for the human health risk assessment and human health protection.

During the period of the 13th Five-Year Plan, the laboratory mainly focuses on the process of rocky desertification and heavy metal pollution and its treatment technology. The key cultivation directions are: 1) Basic theories and methods of geochemistry; 2) water resources and water environment of the plateau river and deep water lake reservoir; 3) Geochemical records of environmental and climate changes.
