摘要

Perchlorate is not as hazardous as U.S. EPA scientists estimated, but it is more harmful than many perchlorate manufacturers have suggested, says a National Academy of Sciences (NAS) committee in a long-awaited report released on January 10. The safe dose recommended by the committee, 0.7 micrograms per kilogram of a person's body weight per day (μg/kg-day), is 23 times higher than EPA's draft reference dose but at least 7 times lower than perchlorate industry groups' recommendations. The report, however, is unlikely to dispel controversy about safe levels of perchlorate in drinking water because calculating such levels involves additional information about exposure sources as well as choices about whom to protect, according to Alan Roberson, who is regulatory affairs director at the American Water Works Association in Washington, D.C.
