DATA SOURCES Biological or fate data provide the basis to the development of the quantitative structureactivity relationships QSARs described in this book. This introduction to data sources is not meant to be comprehensive but to provide information on some of the more easily accessible and useful data sources particularly in the environmental field. This includes the toxic effects of chemicals on aquatic and terrestrial organisms. A. Books There is a variety of books and monographs that provide listings of data of environmental relevance. For example several handbooks should be mentioned such as the Handbook on Physical Properties of Organic Chemicals Howard and Meylan 1997 which lists both experimental and estimated physicochemical properties for over 10 000 substances. The CRC Handbook of Chemistry and Physics known universally as the Rubber Handbook has a large section on organic chemicals with basic physicochemical information Lide 2001 . Other handbooks with toxicological information include the Handbooks of Ecotoxicological Data Devillers and Exbrayat 1992 Kaiser and Devillers 1994 . In the drug field the Merck Index Budavari et al. 1996 has been a standard compendium for researchers for decades. It continues to be available in hardcover but has recently also become available on the web to subscribers of the Dialog and .
