Tox Town Fact Sheet
Tox Town is designed to give you information on everyday locations where you might find toxic chemicals; non-technical descriptions of chemicals; links to selected, authoritative chemical information on the Internet; how the environment can impact human health and Internet resources on environmental health topics.
Tox Town uses color, graphics, sounds and animation to add interest to learning about connections between chemicals, the environment, and the public's health. Tox Town's target audience is students above elementary-school level, educators, and the general public. It is a companion to the extensive information in the TOXNET collection of databases that are typically used by toxicologists and health professionals.
You can explore Tox Town by selecting Neighborhoods, Location links or Chemical links.
I went to this page, For Teachers - Classroom Activities and Discussion Questions [at the High School and College level], and browsed Haz-Map by Processes and Adverse Effects for Mining and found 65 results linking to articles ranging from Hydrogen Sulfide to Diesel Exhaust and Cyanides.
