TRI TOXICS TRACKER has replaced TOXMAPS. This is a link 
to the interactive map and Toxics Release Inventory
 with historical data which has now been
 updated by the EPA to 2020.

Why should you care about the toxics you have been exposed to in your environment? The following links are  some of the worst and most common toxic substances released into the environment or leaking from Superfund sites. They describe both the geographic distribution of these chemicals and their association with chronic diseases including cancer. Only by knowing where and when these substances have polluted the air, water and soils can we hope to reduce exposures in the future.
