TOXMAP, a Geographic Information System (GIS) from the National Library of Medicine's Division of Specialized Information Services, has added some spiffy new features:

The TOXMAP widget allows you to launch a TOXMAP search from your blog, wiki, or Web page. Enter a ZIP code into the widget to see a map of Toxic Release Inventory facilities and Superfund NPL sites, or click "More info" to go to the TOXMAP home page. 

The TOXMAP Toolbar lets you search TRI releases, Superfund National Priorities List (NPL) sites by contaminant, or TRI facilities and Superfund NPL sites by ZIP code -- all from your browser search box.

TOXMAP also has updated mortality data to "layer" onto your map.
