It's always great to learn about an interesting new resource for teaching college students about environmental health, and this one is quite handy. Created as part of the Science Education Resource Center at Carleton College, the Environmental Health Risk Assessment site helps instructors and students "locate and use some of the numerous health-related tools and databases that can be found on the web." Here visitors can look over the Tutorial, which is designed to give interested parties a step-by-step example of how to perform an environmental health risk inventory. Also, the site includes an activity that can be used in the classroom, along with a list of vetted mapping tools available across the Web. The site is rounded out by four external links to related resources, including one that looks at the relationship between geology and human health.
