As with other controversial issues, activists on both sides of the gun issue have created many useful web sites. Because they offer overviews and links to news and source materials, such sites provide a good jumping-off place for research. Of course, as you explore the web, you will encounter many references to books and other printed materials that are not available online. It will then be time to use the library and its catalog and other bibliographical tools. This chapter describes some of the most important and useful research tools, both online and traditional.

This International Resources Guide to Hazardous Chemicals also includes resources for chemical, environmental and industrial safety and hygiene information chemical industry associations, international government environmental agencies, United States environmental agencies, State agencies, Poison Control Centers, and a guide to Hotlines, Databases, and Useful Web sites. 

Many resources were used to compile the information in this book. The hazardous chemicals listed here are taken from Sittig, 4th Edition. For a few chemicals in Sittig, their makers are not listed, perhaps because they are made in such limited quantities that they are sold through specialty middlemen and catalog houses. The primary resources for preparing the list of manufacturers in this book were (1) the Web sites of the companies, (2) membership in special sections of United States chemical societies, the European Chemical Industry Council (CEFIC) and societies in India, Japan, Asia, Italy and elsewhere, and (3) sites in which companies register themselves as producers of particular products, such as the Thomas Directories in the U.S. and Europe, the American Chemical Society ChemCyclopedia, and the British Chemical Industries Association Chemextra. Direct access to these sites are quickly available to any Internet user. They are listed in Section VII - Hotlines, Databases and Useful Web Sites. 

Their easy-to-use Web sites rank produce by levels of contamination, provide information about pesticides in your pet food and meat, and much more. 

It has recently been discovered that nitric oxide (NO, nitrogen II oxide to be precise) is present in the body. It performs many functions, even though it is only present in very small quantities and sometimes lasts only a fraction of a second. Sometimes it is stabilized by reacting with other substances. How could this compound have been made in the body Useful web sites to research on this topic are www.hhmi.org/ science/cellbio/stamler.htm and girch2.med.uth.tmc.edu/faculty/fmurad/index.cfm... 

Ga NMR studies have received increased impetus as a viable probing tool for some key areas. Ga NMR studies have been used to support and follow Ga antitumor agents and their mode of action and uptake into tumor cells. Ga NMR has thus been used to study how various ligands may form complexes with the cation. In another area, the use of - Ga NMR has been used to examine defects in semiconductors, which can have a crucial influence on the semiconductors electronic and optical properties. In addition, a number of very useful web sites detailing Ga NMR related studies are available. " ...
