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 health effects and risks, diet and cancer, food safety, drinking water, garden chemicals, and other topics. Also available at the site is the University of California at Davis's Environmental Toxicology Newsletter. The heart of the site, however, is the searchable database, which provides extensive profiles of pesticides, toxicology information briefs, toxicology issues of concern, and fact sheets. Although still under construction, the database of pesticide profiles includes trade name(s), regulatory status, chemical class, formulation, toxicological effects, ecological effects (on birds, aquatic organisms, etc.), environmental fate, physical properties, exposure guidelines, basic manufacturer, and references. For toxicology students, researchers, or the general public, this is a well-written and useful resource.
