STUDY FINDS HUMANS CAN TOLERATE MORE PERCHLORATE THAN EPA LIMIT A National Academy of Sciences (NAS) panel reported Monday (January 10) the results of a study that concluded that humans could tolerate exposure to perchlorate at levels higher than those proposed by the Environmental Protection Agency (EPA). EPA asked NAS to conduct the study in order to provide input for its efforts to prepare a drinking water standard for perchlorate. The study recommended an acceptable exposure limit equal to about 70 parts per billion, an amount that is 20 times greater than the three parts per billion reference dose EPA had drafted in its 2002 risk assessment. This amount should protect the health of even the most sensitive populations. Perchlorate, used in rocket fuel and munitions, has been found in milk and lettuce as well as in the drinking water supply in 35 states. Studies have shown it can impact thyroid functions.
