We are featuring one of the MERLOT Classics Award winners, "Tox Town." Tox Town is an interactive learning resource developed by the National Library of Medicine to provide information about the location of toxic substances in our environment. The learning resource is available in both English and Spanish. It includes a teachers guide designed for K-12 teachers. Tox Town consists of five neighborhoods (city, farm, town, border, and port) where environmental concerns abound.
