摘要

Traces of perchlorate are found in rain and snow and can be created in lab experiments simulating tropospheric processes, according to research published in this issue of ES&T (pp 1569-1575). These observations suggest that there is a natural flux of atmospheric perchlorate to the earth and a natural perchlorate background level, says corresponding author Purnendu Dasgupta from Texas Tech University. Facilities that manufacture or use perchlo-rate-containing rocket fuel appear to be the source of most contamination plumes. For several years, controversy has swirled around estimates of the health risks posed by perchlorate in drinking water. The U.S. EPA and environmental groups contend that only very low concentrations are safe, while the U.S. Department of Defense and its contractors support higher levels. A National Academy of Sciences committee concluded in January that perchlorate is about 23 times less hazardous than EPA had estimated (Environ. Sci. Technol. 2005, 39, 96A-97A).
