About ToxFAQs™
The ATSDR ToxFAQs™ is a series of summaries about hazardous substances. Information for this series is excerpted from the ATSDR Toxicological Profiles. Each fact sheet serves as a quick and easy to understand guide. Answers are provided to the most frequently asked questions (FAQs) about exposure to hazardous substances found around hazardous waste sites and the effects of exposure on human health.
Each ToxFAQs™ is available in both the standard HTML format below or in the PDF format which provides the familiar two page print version widely used at community meetings and distributed via our mailing list. This PDF format requires Adobe Acrobat Reader external icon, which can be downloaded free from the Adobe web site.
