The Gila River Pima and Tohono O'odham Tribes in Arizona, USA have the highest rates of Type II diabetes in the world. They also don't live very far from one another. In light of all the recent studies indicating a link between DDT (DDE) exposure and the onset of type II diabetes, I decided to try and find out if there were any sources of DDT in the Traditional Territories of these two people. Apparently DDT has been found in the fish and water near these two peoples.
Here is a map and test data produced by the Arizona Department of Transportation (you can make it larger) showing where DDT and other chemicals have been found in the fish and waters near these two groups of people:
