The mission of the environmental sciences graduate program is to cultivate students perspectives of environmental issues and provide students with refined knowledge of environmental issues at the local, regional and global scale. The program will increase the student's technical competence in addressing and analyzing these issues, their origins, ramifications and resolutions. The environmental sciences graduate program at SIUE is designed to enhance and promote professional education and career opportunities in a wide area of interests. Faculty from several departments in the College of Arts and Sciences provide mentoring, direction and instruction. Practicing professionals also lend their expertise to this program. A close relationship is maintained with industries and environmental agencies so that both students and faculty members can incorporate real-world issues in their studies and research. The program offers challenging environmental research opportunities, which may be related to the campus, home, municipality, business and industry, state or federal government, consulting firms, and various advocacy groups. The department has access to a variety of instrumentation, such as an atomic absorption spectrometer, an Inductively-Coupled Plasma-Mass Spectrometer, computer access to Geographical Information System, several gas and liquid chromatographs, a mass spectrometer, nanoparticle analyzer, carbon-nitrogen-sulfur analyzer, a variety of sampling equipment (automated water samplers, low and high volume air samplers, several soil and sediment coring devices) and a thermal cycler for real-time PCRs. In addition, the program has several field sites for long-term environmental monitoring studies, including recently developed experimental filter strips and restored Oak Savannah Prairie.
