Perchlorate in food

摘要

Food is the primary source of perchlorate for most Americans, and U.S. toddlers on average are being exposed to more than half of the U.S. EPA's safe dose from food alone, according to a new U.S. Food and Drug Administration (FDA) diet survey designed to provide perchlorate and iodine intake av-rnerages from food for the entire U.S. Even though the new study is silent on intake by highly exposed populations, several lawmakers and environmental advocates renew their calls for a national perchlorate drinking-water standard, but EPA is not divulging its plans.
