Toxicological Profile for Sulfur Trioxide and Sulfuric Acid

CAS#: Sulfur Trioxide 7446-11-9; Sulfuric Acid 7664-93-9

Toxicological Profile Information

The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The complete list of topics covered (chapter titles) is shown at the left and in more detail further down this page.

The focus of the profile is on health and toxicologic information. Therefore, each profile begins with a Public Health Statement that summarizes in nontechnical language, a substance's relevant properties.

A useful two page information sheet, the ToxFAQsTM, is also available.
