New study on low perchlorate levels and thyroid changes

Below is a link to a study by Blount, et al., published in Environmental Health Perspectives on October 5. CWQ is attempting to confirm if indeed, as the study suggests, any changes in thyroid levels are within normal ranges and therefore there are no adverse affects associated with the statistical correlation shown in the data. Also unclear is the possible source of the perchlorate exposure.

Dr. Blount will be presenting these findings in more detail on October 12 at the East Valley Water District Conference in Ontario, California. Watch this site for more information. In the meantime, the following list of scientific experts may be useful sources of additional information.
