Environmental biotechnology 'US Environmental Protection Agency: http:llwww.epa.gov/ The site of the US Environmental Protection Agency provides information about its organization, laboratories, regulations and publications. The EPA programs and initiatives are also briefly detailed. Some topics are: air and radiation, hazardous waste, pesticide, pollution prevention, recycling, toxic and water treatments. Access to several databases, useful for understanding the environment, is available as well as environment-related software. 'The Center for Environmental Biotechnology! http:l/www.ra.utk.edulceb/home.htm The Center for Environmental Biotechnology (CEB), at the University of Tennessee, was founded in 1966 and is one of the oldest environmental biotechnology research centers in North America CEB investigates the practical application of biotechnology to environmental remediation. The web site gives descriptions of their ongoing research projects and provides links to other related sites. 'LLNL Environmental Technologies Program! http:/lwww-ep.es.llnI.gov/www-ep/aet.htmI The Lawrence Livermore National Laboratory (LLNL) Environmental Technologies Program (ETP) web site. LLNL is operated by the University of California under a contract with the US Department of Energy. The ETP conducts fundamental and applied research to develop, demonstrate, and commercialize innovative technologies for solving environmental problems. This sewer gives information about the ETP programs and access to other environmental technology sites. Bioremediation 'NABIR program.' http://www.lbl.gov/NABIR/ The Natural and Accelerated Bioremediation Research (NABIR) program is a project sponsored by the US Department of Energy's (DOE) Office of Health and Environmental Research (OHER). NABIR's mission over the next ten years is to provide the scientific understanding needed to use and accelerate natural processes for the bioremediation of contaminated soils, sediments, and groundwater at DOE facilities. Information on other bioremediation programs can also be accessed from this page. 'BiocatalysisIBiodegradation Database.' http://dragon.labmed.umn.edu/-lynda/aboutBBD.html The web site of the BiocatalysieJBiodegradation Database (BBD), at the University of Minnesota. The BBD contains information on microbial biocatalytic reactions and biodegradation pathways for primarily xenobiotic, chemical compounds. 'Utah Water Research Laboratory.' http:Ilpublish.uwrl.usu.edu/aqmayQ4.html The Utah Water Research Laboratory (UWRL) objective is to enhance and expand scientific understanding and engineering technology for environmental and water resource management. Its web site provides information about their ongoing multidisciplinary projects, such as environmental engineering, ground water, fluid mechanics and hydraulics, hydrology, natural systems engineering, water education, and water resources management. Access to Aquarius articles pertinent to bioremediation is also given. 'Nitrated polycyclic aromatic hydrocarbons.' http:Ilprfdec.natur.cuni.cz/-cvacka/npah_ahtm The web site of the UNESCO Laboratory of Environmental Electrochemistry provides information about their work related to nitrated polycyclic aromatic hydrocarbons (NPAH), especially on their determination by pojarography, voltammetly and liquid chromatography.
