The profile includes a Minimal Risk Level for oral exposures with a chronic reference dose (RfD) of 0.0007 mg/kg/day for the chronic oral MRL for the perchlorate anion. This value is based on a 2005 National Academy of Sciences report and is the value that EPA has also adopted. The results from newer studies did not change ATSDRs bottom-line recommendation.
