The Center for Public Integrity has obtained a health study suppressed by the Center for Disease Control’s Agency for Toxic Substances and Disease Registry. The study, which was due to be released last July, documents enviornmental hazards in the Great Lakes region.

According to CPI, the study “warns that more than nine million people who live in the more than two dozen ‘areas of concern’—including such major metropolitan areas as Chicago, Cleveland, Detroit, and Milwaukee—may face elevated health risks from being exposed to dioxin, PCBs, pesticides, lead, mercury, or six other hazardous pollutants … In many of the geographic areas studied, researchers found low birth weights, elevated rates of infant mortality and premature births, and elevated death rates from breast cancer, colon cancer, and lung cancer.”

CPI has released excerpts of the study on its website.
