Health & Environmental Research Online (HERO)"Health and Environmental Information Online (HERO), a continuously updated database of "hundreds of thousands" of sources considered for and/or used in human and ecosystem risk assessments, is prepared by the EPA's National Center for Environmental Assessment (NCEA). The recent public release of this database provides a unique opportunity for users to discover sources deemed important by NCEA literature researchers, who welcome suggestions for additional items to consider for inclusion. Although most sources are peer-reviewed journal articles, the database includes other articles, books, book chapters, reports, patents, Web sites, computer programs, pamphlets, public laws, and personal communications. The attractive home page summarizes content, offers topic browsing, and shows links to recent risk assessments and related sources, FAQs, and the search page.
Although searching is straightforward, help with searching, viewing, refining, and exporting results to bibliographic software appears on every page via the How to Use HERO link. To view the full record of a source, users click within its row and scroll to the bottom of the page. Full records link to risk assessments, if any, that include the source; some also display links to publicly available content, institutionally subscribed material, or a publisher's Web site for purchasing source material. The scope is rather broad: in an attempt to force a negative search, this reviewer searched for "elephants" and found 19 journal articles, although a sampling of those records indicated that they were not used as sources in risk assessments." from Choice September 2010.
