have completed their requirements, and the remaining are in the process of completing their work for M.S. degrees (RCEES 1991).

RCEES has several well-equipped laboratories, with instrumentation that includes a high-resolution X-ray fluorescence spectrometer with double crystals, a high-frequency plasma emission spectrograph, a Fourier transform infrared spectrograph, a combined gas chromatograph and mass spectrometer, an X-ray diffraction and fluorescence spectrograph, a laser spectrometer, a UV/visible light spectrophotometer, an ion chromatograph, an atomic absorption spectrophotometer, a gas chromatograph, a high-pressure liquid chromatograph, a polarograph, a thermal energy analyzer, a differential thermal analyzer, and a computer work station. In addition, RCEES has a VAX780 computer shared jointly with three other CAS institutes, direct computer connections with an institute in Germany, and about 20 PCs.

About one-third of RCEES's funding comes directly from CAS, the remainder from NEPA, NSFC, and contracts from local governments.

RCEES has a library with a collection of more than 110,000 volumes published in many different languages and a collection that comprises 349 Chinese and foreign scientific journals. In addition, a collection of about 15,000 documents from more than 100 institutions is kept in a regular information exchange link within the country. The Chinese unit of INFOTERRA (UNEP's international environmental database) is also based at RCEES. RCEES staff edit two important journals: Environmental Chemistry (Huangjing Huaxue, bimonthly, in Chinese) and Environmental Science (Huangjing Kexue, bimonthly, in Chinese). Additionally, Zhuang Yahui is the editor of Acta Scientiae Circumstantiae (Huangjing Kexue Xuebao [Journal of Environmental Sciences], quarterly, in Chinese), which is perhaps the top journal of environmental science being published in China.

Of the seven RCEES divisions, four are contributing to or have the potential to contribute to global change research. The Regional Eco-environmental Assessment and Planning Division has three ecology laboratories and a research group for agricultural and soil chemistry. The Eco-environmental Effects of Chemicals Division includes research groups for atmospheric chemistry, ecological chemistry, biogeochemistry, chemical ecology, organic chemistry, and ecotoxicology. The Environmental Analytical Chemistry Division has four laboratories. The Eco-environmental Information Studies Division has five
