This is Not a Controlled Research Study

Because of the number of people tested, the study results cannot be used to draw statistical conclusions about chemical exposures for certain represented groups, or the Oregon population as a whole. The data presented in this report provide a snapshot of the levels of some chemicals in a small, diverse, cross-section of Oregonians. The only statistically-based compilation of measurements is the National Report on Human Exposure to Environmental Chemicals conducted by the U.S. Centers of Disease Control and Prevention. The National Report on Human Exposure to Environmental Chemicals does not test for all the chemicals assessed in our project.
