The "Anaerobic Biodegradation of Organic Chemicals in Groundwater" report and database are available at this site. The report (.pdf format), by Syracuse Research Corporation (SRC), reviews anaerobic groundwater biodegradation literature "for 44 common organic chemicals (including BTEX, chlorinated aliphatic compounds, phenolic compounds, common freons, ketones, organic acids, and polychlorinated...

Green Chemistry, as its name implies, is an environment friendly practice of using chemistry to prevent pollution. The US Environmental Protection Agency (EPA) created the Green Chemistry Expert System software that can be freely downloaded from this site. The program can be used to assess hazardous substances in chemical reactions, learn about green synthetic methods, design safer chemicals by...

A cooperative effort of University of California-Davis, Oregon State University, Michigan State University, Cornell University, and the University of Idaho, EXTOXNET (the Extension Toxicology Network) is an online resource providing "objective, science-based information about pesticides" and other toxic chemicals. First-time viewers will find useful information in the FAQ section, which covers...

This special feature page from the American Chemical Society (ACS) showcases the up-and-coming field of "green chemistry," that is, the development of chemical products and processes that eliminate or reduce the use and generation of hazardous substances. A list of principles behind green chemistry, a searchable bibliography of green chemistry references, green chemistry links (including...

With administrative offices in North America and Europe, the non profit Society of Environmental Toxicology and Chemistry (SETAC) was founded in 1979 to serve as a forum for individuals and institutions partaking in environmental issues, education, and research. At this Web site, professionals can discover employment opportunities that are committed to ethical professional conduct. Potential...

This week's In The News highlights the discovery of a new process that could separate problematic chemicals from ionic liquids. In industry, chemical reactions are performed in toxic organic solvents and some can form carbon dioxide and other greenhouse gases. Specifically, the vapor pressure of these organic solvents is hazardous because these "solvents evaporate easily into the air." The effects...

Tox Town, a Web-based project of the National Library of Medicine (NLM), is "an interactive guide to commonly encountered toxic substances." This highly visual Web site provides a wealth of information and related resources, such as an introduction to everyday locations where toxic chemicals might lurk, non-technical descriptions of toxins, the effect of toxins on human health, and more. Users...
