The analysis draws on the recent health effects review published in 2005 by the National Research Council (NRC). We focus on the potential level of risk borne by the NRC-identified most sensitive subpopulation (pregnant women and hence their fetuses). Other members of the population should be at a level of risk below that calculated here, and so protection of the sensitive subpopulation would protect the general public health. The analysis examines the intersubject distribution of risks to this sensitive subpopulation at various potential drinking water concentrations of perchlorate and also draws on estimates of the national occurrence of perchlorate in U.S. CWSs to estimate the variability of risks under defined regulatory scenarios. Results suggest that maximum contaminant levels (MCLs) of up to 24.5 \u03bcg\/L should pose little or no incremental risk to the large majority of individuals in the most sensitive subpopulations exposed in the United States at current levels of perchlorate in water. The protectiveness of an MCL of 24.5 \u03bcg\/L depends, however, on whether the study subjects in the health effects data used here may be assumed to have been exposed to background (non-drinking water) contributions of perchlorate.<\/jats:p>","DOI":"10.1289\/ehp.8459","type":"journal-article","created":{"date-parts":[[2006,3,16]],"date-time":"2006-03-16T17:41:24Z","timestamp":1142530884000},"page":"975-979","source":"Crossref","is-referenced-by-count":9,"title":["Intersubject Variability of Risk from Perchlorate in Community Water Supplies"],"prefix":"10.1021","volume":"114","author":[{"given":"Doug","family":"Crawford-Brown","sequence":"first","affiliation":[{"name":"Department of Environmental Sciences and Engineering and Carolina Environmental Program, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bob","family":"Raucher","sequence":"additional","affiliation":[{"name":"Stratus Consulting Inc., Boulder, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Harrod","sequence":"additional","affiliation":[{"name":"Stratus Consulting Inc., Boulder, Colorado, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2006,3,16]]},"reference":[{"key":"2026081311032301800_micit1","author":"Brandhuber"},{"key":"2026081311032301800_micit2","doi-asserted-by":"crossref","first-page":"1569","DOI":"10.1021\/es048612x","article-title":"The origin of naturally occurring perchlorate","volume":"39","author":"Dasgupta","year":"2005","journal-title":"Environ Sci Tech"},{"key":"2026081311032301800_micit3","doi-asserted-by":"crossref","first-page":"927","DOI":"10.1289\/ehp.02110927","article-title":"Health effects assessment for environmental perchlorate contamination: the\ndose-response for inhibition of thyroidal radioiodine uptake in humans","volume":"110","author":"Greer","year":"2002","journal-title":"Environ Health Perspect"},{"key":"2026081311032301800_micit4","first-page":"3401","article-title":"Iodine nutrition in the United States.
