The information in the toxics pages on the Eco-USA site is largely excerpted from the initial summary chapters of the much more detailed full-text toxicological profiles issued by the U.S. Agency for Toxics Substances and Disease Registry (ATSDR). Current toxicological profiles are available on their website.

In general, the excerpted material consists of text beginning with Section 1.1 of the ATSDR profiles and includes much of Chapter 1. Major omissions include the first few paragraphs, which differ little from profile to profile; references to other chapters of the larger document; and general information not specifically related to the compound(s) in question (for example, justifications of animal testing, or discussion of the differences between regulations and recommendations). Section titles have usually been shortened.

While every effort has been made to excerpt this material accurately and in a manner which preserves the original meaning, there is no substitute for the original document. Eco-USA categorically rejects any responsibility whatsoever for the use of the material in these excerpts.

Also, please keep in mind that some of these profiles are rather old, and that the information in them may have been superceded or contradicted by more recent research.

Printed copies of the full text toxicological profiles are available, for a substantial fee, through the National Technical Information Service.
