The Association of Public Health Laboratories (APHL) developed a Biomonitoring Toolkit. The toolkit has a number of resources, including overarching guidance documents, laboratory methods, communication templates, and stories from the field. There are links that point to other relevant resources. This discussion board, which functions similar to a listserv, facilitates conversation among subscribers about biomonitoring. The site allows for multiple discussion threads to take place at once, as well as a robust search engine for finding old discussion threads. To access the Toolkit, you need to log into APHLs SharePoint site. If you have not used our SharePoint tool, you will need sign up for an account: Visit www.aphl.org and click on Create an Account (upper right). Email [email protected] to let them know which email address you used and it will be added to the Toolkit. If you have any questions with the Toolkit or Discussion Board, please see the Biomonitoring Toolkit User Guide or email [email protected] for assistance.
